Acid Catalysis of Waste Cooking Oils for Biodiesel Production

Biodiesel is receiving increased attention as an alternative, non-toxic, biodegradable and renewable diesel fuel and contributes a minimum amount of net greenhouse gases, such as CO2, SO2 and NO emissions to the atmosphere. Exploring new energy resources, such as biofuel is of growing importance in recent years. The possibility of obtaining oil from plant resources has created a great importance in several countries. Vegetable oil after esterification being used as bio diesel, Considering the cost and demand of the edible oil is bearable, so it may be preferred for the preparation of bio diesel in India. The transesterification of waste cooking oils with methanol as well as the main uses of the fatty acid methyl esters are reviewed. The general aspects of this process and the applicability of different types of catalysts (acids, alkaline metal hydroxides, alkoxides and carbonates, enzymes and non-ionic bases, such as amines, amides, and guanidine and triamino (imino) phosphoranes) are described. Transesterification is carried in a reaction cavity, once the reaction is complete, glycerine and biodiesel are gravity separated.

Nowadays, preservation of natural resources on earth is one of the most important concerns of humanity. In this regard, increasing the consumption of energy is one of the most critical challenges that humans are facing. Because, on the one hand, the untapped use of different sources of energy from fossil fuels can destroy this natural resource and, on the other hand, pollution from the use of these resources is a serious threat to the environment. Recent research suggests that affordable, sustainable and environmentally friendly fuels, which can be a good alternative to fossil fuels, have become more important. Therefore, biodiesel has made it possible to release less greenhouse gas emission and low toxicity emissions, which can partly meet fuel requirements and is the best alternative for petroleum diesel. In addition, the waste cooking oils are a major source of biodiesel for their essential compounds, such as glycerol. The use of waste cooking oils can reduce biodiesel production cost by 60 to 90 percent. Therefore, the main objective of this review is to study the production of biodiesel using transesterification reaction of waste cooking oil as an alternative fuel to petroleum diesel that can be used easily in diesel engines.

The problem of fossil fuel increases by time around the world, Biodiesel is an environmentally friend renewable diesel fuel alternative. The present work aims to determine the possibility for biofuel production from non-edible plant (Water hyacinth) and waste cooking oils in addition to potential uses as source for glycerol, pigments and antioxidant compound sources. this study aimed to investigate the feasibility of biodiesel production from water hyacinth using two solvent systems (chloroform: methanol, 2:1v/v and Hexane), Moreover, WCO applying one steps alkaline transesterification process using methanol, NaOH (0.25) and KOH (0.25, 0.5 and 1g) as a catalyst and hot distilled water for purification. both produced biodiesel (from Eichhornia and WCO) was characterized using FTIR and some chemical constant such as IV, SV and AV. The highest biodiesel produced from Eichhornia recorded with chloroform: methanol system when compared with Hexane. However, the highest biodiesel produced from WCO was recorded when using KOH (0.25g). Also, the obtained results reported the possibility for use glycerol produced from the both biofuel sources in body butter (makhmaria) production, Authors concluded that, the produced biodiesel from both sources was within the recommended standards of biodiesel fuel. Also, water hyacinth became useful in antioxidant compounds production, the contained pigments may be used as natural coloring substances in different fields.

Haphazard mining and consumption of fossil fuels have reduced petroleum reserves causing fossil fuel depletion and environmental degradation; thus, reflecting the need of the cheaper, renewable and eco-friendly alternative source of petroleum to meet the fuel demand. Million liters of edible oil used for cooking foods and date expired oils from oil manufacturers are discarded into sewage. This study primarily intends to study the feasibility of biodiesel production using such waste oils. In this work, biodiesel was prepared from waste cooking oils by a process called transesterification with NaOH as a catalyst. Our results showed that methyl ester (biodiesel) (92.67±0.90%), soap materials (1.33±0.224%) and glycerol (6±0.68%) were obtained after the transesterification of waste cooking oil. The physicochemical properties of biodiesel such as density, viscosity, volatility, surface tension and flashpoint were analyzed, which were found to be 0.862±0.006 g/cm3, 2.23±0.021 cP, 0.327×10-3±4.5×10-6 g/s, 32.03±0.138 dyne/cm, 169.67±0.810°C, respectively. These properties were compared with that of commercial diesel as well as with the values specified by the American Society for Testing and Materials (ASTM) D6751. The density and the surface tension of the biodiesel were found similar to that of petrodiesel but its volatility was 3 times lower. Fourier-transform infrared spectroscopy (FTIR) spectra of the biodiesel showed methyl ester functional group at 1436 cm-1. Based on the cost of the materials used for production, the cost of biodiesel was estimated to be about 81 Nepalese rupees (0.67 USD) per liter. The properties of biodiesel also met the standard values of ASTM D6751. These findings indicate that waste oil is one of the feasible biodiesel sources and it can be used as a suitable alternative to petrodiesel.
