Abstract It is well known that biodiesel from pure coconut oil is suited best for diesel engine operation. However, the commercialization of coconut oil biodiesel is unfeasible due to its higher cost and demand as a food material. In this study, biodiesels were produced from coconut testa oil and coconut waste cooking oil, two waste feedstock derivatives of coconut. Fatty acid composition and properties such as density, calorific value, kinematic viscosity, cloud and pour points, flash and fire points, Conradson carbon residue, and copper strip corrosion of these two biodiesels were determined and compared with those of fresh coconut oil biodiesel and the standard diesel. It was found that the properties and fatty acid profiles of all three biodiesels were similar. Furthermore, from the engine testing using B20 (diesel-biodiesel blend with 20% biodiesel) blends of prepared biodiesels, it was found that the engine performance, emission, and combustion characteristics were comparable for coconut testa oil and coconut waste cooking oil biodiesels with fresh coconut oil biodiesel. Thus the coconut testa oil and coconut waste cooking oil can be used as low-cost feedstocks for biodiesel production with all advantages of fresh coconut oil.

Biodiesel Quality

Waste cooking oil is used oil that has been used for domestic purposes and has undergone changes, both physically and chemically. One effort that can be done to reduce the adverse effects of used cooking oil is changed the material used cooking oil into biodiesel. In this study of biodiesel production from waste cooking oil is done by using biodiesel transesterification reaction as generally through a pretreatment in order to reduce the number of Free Fatty Acid in cooking oil. The high number of Free Fatty Acid will complicate the separation of glycerol from biodiesel so that production of biodiesel will be slight. Test parameters of biodiesel quality produced by  transesterification process refers to the Indonesian biodiesel quality standard ISO 7182: 2015. The production of biodiesel from used cooking oil in this experiment using variations methanol and sodium hydroxide solution ratio to the used cooking oil is 1: 2; 1: 4 and 1: 8. Test results showed that the quality of biodiesel is in compliance with ISO 7182: 2015 on the parameters of viscosity, density and flame test. While the Free Fatty Acids remained above the quality standard ISO 7182: 2015.Keywords :    Waste cooking oil, Transesterification, Biodiesel

Cooking Oil

Cost of biodiesel produced from virgin vegetable oil through transesterification is higher than that of fossil fuel, because of high raw material cost. To minimize the biofuel cost, in recent days waste cooking oil was used as feedstock. Catalysts used in this process are usually acids, base, and lipase. Since lipase catalysts are much expensive, the usage of lipase in biodiesel production is limited. In most cases, NaOH is used as alkaline catalyst, because of its low cost and higher reaction rate. In the case of waste cooking oil containing high percentage of free fatty acid, alkaline catalyst reacts with free fatty acid and forms soap by saponification reaction. Also, it reduces the biodiesel conversions. In order to reduce the level of fatty acid content, waste cooking oil is pretreated with acid catalyst to undergo esterification reaction, which also requires high operating conditions. In this review paper, various parameters influencing the process of biofuel production such as reaction rate, catalyst concentration, temperature, stirrer speed, catalyst type, alcohol used, alcohol to oil ratio, free fatty acid content, and water content have been summarized.

Increase in the demand for the alternative fuel for diesel engine as led to quest for feasible fuel with competitive cost and environmental friendly compared to petrolium fuel. This article deals on waste energy recovery. The aim of this experimental work is to find an attractive alternative fuel for the diesel engine by harnessing fuel from waste disposed oils. Waste Cooking Oil (WCO) and Waste Lubrication Oil (WLO) energy sources are used for fuel production. Collected WCO stored in a container, mixed and cleansed by removing solidified fats and other food leftovers before the transesterification. The acid followed by base catalyst transesterification processes carried out for biodiesel production. The WLO oil cannot be used directly in diesel engine and hence it is processed to be used like DLF using pyrolitic vacuum distillation method. The characteristics test such as flash point, fire point, density; viscosity and calorific value of the produced biodiesel, DLF, B10, B20, B30 and B40 were determined & compared with standards. Performance and Emission characteristics conducted in a single cylinder, free aspirated, water- cooled computerized diesel engine setup and results discussed. Results outcome shows that B30 exhibits the similar performance as pure diesel. The results show an improvement in brake specific fuel consumption, thermal efficiency. The unburned hydrocarbons, carbon monoxide emissions less but increase in the NOx.

Background: Waste biomass derived reusable heterogeneous acid based catalysts are more suitable to overcome the problems associated with homogeneous catalysts. The use of agricultural biomass as catalyst for transesterification process is more economical and it reduces the overall production cost of biodiesel. The identification of an appropriate suitable catalyst for effective transesterification will be a landmark in biofuel sector Objective: In the present investigation, waste wood biomass was used to prepare a low cost sulfonated solid acid catalyst for the production of biodiesel using waste cooking oil. Methods: The pretreated wood biomass was first calcined then sulfonated with H2SO4. The catalyst was characterized by various analyses such as, Fourier-transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS) and X-ray diffraction (XRD). The central composite design (CCD) based response surface methodology (RSM) was applied to study the influence of individual process variables such as temperature, catalyst load, methanol to oil molar ration and reaction time on biodiesel yield. Results: The obtained optimized conditions are as follows: temperature (165 ˚C), catalyst loading (1.625 wt%), methanol to oil molar ratio (15:1) and reaction time (143 min) with a maximum biodiesel yield of 95 %. The Gas chromatographymass spectrometry (GC-MS) analysis of biodiesel produced from waste cooking oil was showed that it has a mixture of both monounsaturated and saturated methyl esters. Conclusion: Thus the waste wood biomass derived heterogeneous catalyst for the transesterification process of waste cooking oil can be applied for sustainable biodiesel production by adding an additional value for the waste materials and also eliminating the disposable problem of waste oils.
