Biodiesel is a renewable fuel with similar chemical and physical properties to diesel. The study used waste cooking oil to make biodiesel because reusing waste cooking oil harms human health by raising FFA levels above the norm. Transesterification was performed at 60 °C using a 1:5 methanol to waste cooking oil volume ratio, 30 min reaction time, 600 rpm stirring speed and 1% wt. KOH was employed as a homogenous base catalyst. Biodiesel samples of B0, B2, B5, B20, B40 and B100 were processed at 25 ºC in combination with petrodiesel. Samples were tested for density, kinetic viscosity, flash point, acid value and pH. The fuel economy and flue gas analysis were performed using three-wheeler diesel. The amount of waste cooking oil biodiesel increases the density, kinematic viscosity, flash point, acid value and pH of the sample. In blended diesel, the amount of biodiesel also lowered CO2, CO, NO, NOx, hydrocarbon (HC) and SO2 emissions.

At the present moment worldwide waning fossil fuel resources as well as the tendency for developing new renewable biofuels have shifted the interest of the society towards finding novel alternative fuel sources. Biofuels have been put forward as one of a range of alternatives with lower emissions and a higher degree of fuel security and gives potential opportunities for rural and regional communities. Biodiesel has a great potential as an alternative diesel fuel. In this work, biodiesel was prepared from waste cooking oil it was converted into biodiesel through single step transesterification. Methanol with Potassium hydroxide as a catalyst was used for the transesterification process. The biodiesel was characterized by its fuel properties including acid value, cloud and pour points, water content, sediments, oxidation stability, carbon residue, flash point, kinematic viscosity, density according to IS: 15607-05 standards. The viscosity of the waste cooking oil biodiesel was found to be 4.05 mm2/sec at 400C. Flash point was found to be 1280C, water and sediment was 236mg/kg, 0 % respectively, carbon residue was 0.017%, total acid value was 0.2 mgKOH/g, cloud point was 40C and pour point was 120C. The results showed that one step transesterification was better and resulted in higher yield and better fuel properties. The research demonstrated that biodiesel obtained under optimum conditions from waste cooking oil was of good quality and could be used as a diesel fuel.

Biodiesel is biodegradable, clean-burning, non-toxic, renewable, high-quality, and cheap diesel fuel made primarily from waste vegetable oil which can be used without any alterations in engine design. The paper is concerned with the extraction and quality evaluation of the biodiesel fuels synthesized from waste soya bean cooking oil. Waste soya bean cooking oil had high amount of free fatty acid. Thus, single step transesterification process with the aid of homogeneous catalyst as 1% potassium hydroxide were implemented in this experiment. Methanol was chosen as alcohol solvent. In the transesterification process, the triglycerides in waste cooking oil was reacted with a methanol to form esters and glycerol as by product.The biodiesel were extracted for different oil to methanol ratio as 1:2, 1:3 and 1:4. The highest biodiesel yield of 76% was obtained at 1:3 volumetric ratio for 60 ºC reaction temperature and 1250 rpm stirring speed. Results show that the optimal methyl ester yield of 90% occurred at methanol: oil volume ratio of 3:1. The product met the ASTM fuel standards for relative density, acid value, relative density, calorific value, flash point and kinematic viscosity.

Biodiesel, as an alternative auto fuel for conventional fossil fuel, has drawn wide attention in recent years. In this research, a two-step process for biodiesel production using waste cooking oil as feedstock was studied in a pilot plant with a treatment capacity of 3 ton/d. The results show that: the process exihibited a good conversion ratio and the biodiesel displayed suitable physical-chemical properties in comparison with diesel fuel, such as flash point of 137°C, viscosity of 4.49 mm2/s, acid value of 0.44 mg KOH/g etc. The quality of biodiesel meets the agreement with the European specification defined by EN 14214. Afterwards, the mixture of biodiesel and diesel were test in the engine with a ratio of 50/50(v/v), 20/80(v/v), and 0/100(v/v). It indicates the mixed fuel has a reasonable fuel consumption rates without diesel engine modification, when the biodiesel blended with 0# diesel as fuel. The present results demonstrated that the industrial scale plant would achieve promising objective with waste cooking oils and animal fats as raw material. Also, this biodiesel-based diesel fuel could be applied in Tianjin local public transportation system that improves its sustainable development.

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.

Studying biodiesel as an alternative fuel is important for finding the most suitable fuel for the future. Biodiesel from waste cooking oil is one of the alternative fuels to replace fossil oil. Waste cooking oil is the used oil from cooking and is taken from hotels or restaurants. The emulsion of waste cooking oil and water is produced by adding water to the oil, as well as some additives to bind the water and the oil. In this study, the fuel properties of 100% biodiesel waste cooking oil  are compared to several blends by volume: 5% of biodiesel waste cooking oil blended with 95% diesel oil (BD5), 10% of biodiesel waste cooking oil blended with 90% of diesel oil (BD10), 5% of biodiesel waste cooking oil blended with 10% of water and 18.7% of additives (BDW18.7), and 5% of biodiesel waste cooking oil blended with 10% of water and 24.7% of additives (BDW24.7). The objectives of this study are to establish the properties and characteristics of the FTIR (Fourier-transform infrared spectroscopy) of biodiesel-water emulsions from waste cooking oil and to compare them to other fuels. The chemical properties of the fuels are analyzed by using the ASTM D Method and FTIR  to determine the FAME (fatty acid methyl ester) composition of biodiesel in diesel oil. The results showed that the addition of additives in the water-biodiesel oil increases the viscosity, density, and flash point. However, it decreased the caloric value due to the oxygen content in the fuel.

This work has investigated the reusability of silica-titania in various temperatures (50 – 70°C) of biodiesel production from waste cooking oil. The reused silica-titania catalyst collected from silica-titania catalyst waste produced from the process of separating the catalyst from biodiesel products from palm oil and used cooking oil at various temperatures. The 1st and 2nd reused SiO2-TiO2 were characterized by DR UV-Vis and the spectra were deconvoluted for calculate the fraction of titanium in tetrahedral coordination. In addition the biodiesel products were characterized using FTIR, and several properties of biodiesel such as density, flow rate and acid value were analyzed in order to get the information about catalytic activity reused SiO2-TiO2. The results show the titanium tetrahedral fraction in reused catalyst (1st) and (2nd) are found to be 24,98% and 24.65%, respectively. The FTIR characterization of biodiesel products and waste cooking oil are almost similar. The analysis of waste cooking oil converted to biodiesel shows an optimum temperature of 50oC that at this temperature the lowest density or highest flow rate gave highest conversion of 47.82% using BCR1 and 39.13% using BCR2.
