Cooking Oil

In recent decade, the demand for fuel as a source of energy has been dramatic. In fact, many oil and gas reservoirs are declining around the world. The use of fossil fuels such as oil, coal, and natural gas is contributing to the phenomenon of global warming. This is because it emits high quantities of carbon dioxide and other greenhouse gases to the atmosphere. Thus, many researchers and energy companies are investigating the production of an environmental friendly fuel that reduces the emission of greenhouse gases. Thus, bio fuel is one of the most obvious alternative sustainable fuels that can be produced from used vegetable oil and animal fats as well. Indeed, it has several advantages. For example, a biodegradable and a renewable energy reduces global warming phenomenon. Thus, this work is an attempt to produce a biodiesel fuel from chicken fat and waste cooking oil. Also, it was found that it is possible to produce biodiesel from chicken fat and waste cooking oils using transesterification reaction method. Furthermore, the process optimization was also adopted; for example, methanol to oil ratio. It has been found that the yield percentages of the produced biodiesel is increased by increasing the amount of methanol. In addition, the maximum conversion to ester could be achieved at methanol: oil ratio about 7:1. at 60 °C.

Cooking Oils

Biodiesel is a renewable energy resource consisting of the alkyl monoesters of fatty acids obtained from vegetable oils, waste cooking oils, or animal fats. Biodiesel has been noticed recently as an alternative to fossil fuels. Previous studies have shown that biodiesel produces less pollutants compared to diesel fuel. Biodiesel fuel increases the emission of NOx exceptionally. Recently, it has been found that antioxidant addition to biodiesel is a solution to solve the problem. The purpose of this research is to study the effect of antioxidants addition on the emissions of CO, HC, and NOx from biodiesel fuel. Exhaust emissions of an agriculture diesel engine were studied using biodiesel blend with a 500 ppm propyl gallate (PrG) (propyl-3,4,5-trihydroxybenzoate) and butylated hydroxy anisole (BhA) (2-tert-butyl-4-methoxyphenol) as two major antioxidants. Biodiesel used in this research was prepared through NaOH catalyzed transesterification of a waste cooking oil that originally was taken from sunflower oil, with the assistance of ultrasonic homogenizer. After biodiesel production, five blends including neat diesel, B10, B20, B20 + 500 ppm PrG, and B20+ 500 ppm BhA were used as fuel and the emitted gases were analyzed. The results of this work demonstrated that the addition of antioxidants has no significant effect on lowering CO emission, as well as lowering HC; but the addition of antioxidants results in more efficient reduction of NOx emission from diesel exhaust. In general, BhA showed better results compared to PrG.

The Impact

The use of fossil fuels as energy sources has grown to significantly be likely to have a major environmental impact. Reduction of world oil reserves and increasing environmental concerns have prompted alternative is found and renewable source of energy called biodiesel. Biodiesel fuel from vegetable oil is considered as the best candidates for diesel fuel replacement in diesel engines because of its closer. Fuel prices are going up day by day in the world. Thus, the means and methods have been trying for years to get fuel alternative outcomes. This study investigated the effects of different storage periods used in quality biodiesel blends (B5, B10, B15) of waste cooking oil and diesel fuel under low temperature and the temperature of the environment. Biodiesel samples were stored in glass containers under indoor conditions, and outdoor conditions for 10 weeks in total. These samples were monitored on a weekly basis through the test properties. The experimental density, viscosity, acid value, water content and flash point discussed in detail. Biodiesel storage at low temperatures is suitable and more advantageous because the impact on the physical properties is minimal and beneficial to slow down the degradation of biodiesel and storage.

Cooking Oil

Lack of awareness and knowledge of environmental protection, many people discard cooking oil waste. According to several studies, cooking oil waste can be processed into more valuable products through certain processes that require energy and material. Biodiesel is an example. Beside biodiesel, the production process also produces non-product output. Thus, efforts to utilize cooking oil waste into more valuable products also have a negative impact on the environment. This study aims to measure the environmental impact of biodiesel production from waste cooking oil and compare it if it is discharged to landfill without the recycling process. Measurement of environmental impacts is carried out using a Life Cycle Assessment. Measurement of the environmental impact of biodiesel processing from cooking oil waste is based on a process carried out at a research institute. The measurement results state that the disposal of cooking oil waste has an adverse effect on the ecotoxicity category. Whereas the processing of cooking oil waste into biodiesel has advantages in the categories of climate change, the formation of photochemical oxidants, fine dust, oil and gas depletion, and water pressure indicators. the level of eco efficiency from processing waste cooking oil to biodiesel produces a value close to one which means that the production process is affordable but not yet sustainable.

The depletion of fossil fuels as well as the rises of greenhouse gases had caused most government worldwide to follow the international energy policies for the use of biodiesel. One of the economical sources for biodiesel production is waste cooking oil. The use of waste cooking oil is more sustainable if they can perform similarly to conventional diesel fuel. This paper deals with the experimental study carried out to evaluate the engine performance and exhaust emission of diesel engine operated by biodiesel from waste cooking oil at various engine speed. The biodiesel used are known as B5, which contains of 5% of waste cooking oil and 95% of diesel fuel. The other one is B20, which contains of 20% of waste cooking oil plus 80% of diesel. Diesel was used as a comparison purposes. The results show that power and torque for B5 give the closest trend to diesel. In terms of heat release, diesel still dominates the highest value compared to B5 and B20. For exhaust emission, B5 and B20 showed improvement in the reduction of NOx and PM.

The Cost

The increasing awareness of the depletion of fossil fuel resources and the environmental benefits of biodiesel fuel has made it more attractive in recent times. Its primary advantages deal with it being one of the most renewable fuels currently available and it is also non-toxic and biodegradable. It can also be used directly in most diesel engines without requiring extensive engine modifications. However, the cost of biodiesel is the major hurdle to its commercialization in comparison to petroleum-based diesel fuel. Biodiesel is proved to be a potential candidate for partial substitute of mineral diesel oil. The environmental issues associated with the use of fossil-based energy sources have informed the search for more sustainable energy alternatives. This work investigated the potential of producing biodiesel from waste cooking oil (WCO). The work gives ample evidence that oil from eateries in WCO could be used in producing high quality biodiesel in an easy, one-step transesterification reaction without the need for acid esterification which increases the overall cost of the production process.

The depletion of fossil fuels and the concerned toward environmental sustainability have created a considerable to alternate development of sources of energy as substitute for traditional fossil fuels. The biodiesel production has been reported to be an ideal solution as alternative diesel fuel due to its environmental benefits. Thus, the transesterification of waste cooking oil with methanol in the presence of Mg-Al layered double hydroxide (LDHs) as a heterogeneous catalyst was studied to produce the biodiesel. In this work, Mg-Al-LDH was fabricated via alkali free co-precipitation method with final Mg/Al ratio of 4:1, 3:1 and 2:1. The product of co-precipitation was undergone aging process for 24 h. Then it was placed in oven at 100 ⁰C overnight and finally was calcined at 450 ⁰C for 5 h. The correlation of crystallinity, morphology and particle size of Mg-Al-LDH before and after calcined were examined and compared. X-ray diffraction analyse (XRD) was used to study the textural and structural characteristics of the samples. Particle size, morphology and particle properties were characterize by Brunauer, Emmett and Teller (BET) and Scanning electron spectroscopy (SEM). The bonding and structural of Mg-Al-LDH was studied by Fourier transform infrared spectroscopy (FTIR). Energy dispersive X-ray spectroscopy (EDX) was used for the elemental analysis of the samples. The catalytic activity was evaluated by the transesterification reaction under the following reaction condition: temperature (60 ⁰C-65 ⁰C), time (24 h) and methanol to oil ratio (15:1) .The greatest yield was 85.2% and obtained with combination of 4:1 Mg/Al ratio followed by 3:1 and 2:1 ratio.

Environmental Consequences

The global demand for energy in recent decade has been dramatic. Indeed, several oil and gas reservoirs around the world are depleted every day. Moreover, the fossil fuels for example, petroleum emitted huge quantities of toxic gases to the environment. Therefore, the passive environmental consequences of fossil fuels and the bother about fossil fuel supplies have encouraged the investigation for renewable biofuels. Thus, this work is objective to produce a biodiesel fuel from residual cow tallow that produced every day at Koya city slaughterhouse. The Koya slaughterhouse cow tallow may consider low cost renewable feed stock to produce biodiesel. Furthermore, the study has examined various process parameters for example, catalyst amount and alcohol amount as well on fuel production yield. The produced biodiesel is also subjected into several tests for instance, density and cetane number.

Depletion of fossil fuels, concerns on environment, and fuel price fluctuation have become the major drives in searching for sustainable alternative fuel. In that regard, a study was conducted to evaluate the combustion performance of Waste Cooking Oil (WCO) converted into biodiesel and blended with Conventional Diesel Fuel (CDF) as a mean of sustainable replacement for diesel fuel. In this study, the production of biodiesel fuel from waste cooking oil was done via transesterification process, using the single step approach. The properties of the WCO biodiesel was characterized. The combustion performance of the produced fuels has been studied for B10 and B30 biodiesel from WCO and CDF (as baseline) based on their wall temperature profiles and gaseous emissions generated such as nitrogen oxides (NOx), carbon monoxide (CO) and sulphur dioxide (SO2). It was found that the B30 WCO biodiesel emits lower emission compared to CDF but at the same time generates a lower temperature profile.

In this research work, biodiesel production by trans-esterification of three raw materials including virgin and used edible oil and non edible oil has been presented. A two step method following acidic and alkali catalyst was used for non edible oil due to the unsuitability of using the straight alkaline-catalyzed trans-esterification of high FFA present in rice bran oil. The acid value after processing for rice bran, cottonseed and waste cooking oil was found to be 0.95, 0.12 and 0.87 respectively. The influence of three variables on percentage yield i.e., methanol to oil molar ratio, reaction temperature and reaction time were studied at this stage. Cottonseed oil, waste cooking oil and rice bran oil showed a maximum yield of 91.7%, 84.1% and 87.1% under optimum conditions. Fuel properties of the three biodiesel satisfied standard biodiesel fuel results.
