Research about modification of CaO catalyst to produce biodiesel has done. This research aims to know the effectiveness of CaO-ZnCl2 belong to ASTM D6751 to get a yield biodiesel.  Modification of the CaO with ZnCl2 was conducted by impregnation method using methanol and n-hexane. For synthesis biodiesel, methanol is used as solvent and Waste Cooking Oil (WCO) as raw material. Ratio molar of WCO and methanol is 12:1 with 3% CaO-ZnCl2 added.  This reaction is carried out at a temperature of 65oC. the biodiesel is characterized by Fourier Transform Infrared (FT-IR) to determine the presence of ester groups formed. The yield percentage of biodiesel produced is 77.94%. The characterization of biodiesel properties consist of acid number is 73.38 mg KOH/g, density is 0.9038 and water content is 0.0053%.

In this study, the catalyst ZnAl layered double hydroxides (LDH) were successfully being synthesised with molar ratios 4:1 and 3:1 via free-alkali method by using ammonia solution instead of sodium hydroxide. The catalyst has been characterised before and after calcination by using XRD, TGA, SEM, BET and FT-IR. Based on the XRD result, the crystalline peak was successfully obtained and collapsed into mixed oxides of zinc oxide after the calcination. The carbonate decomposition was analysed by TGA to confirm the decomposition temperature of carbonate anions which is 250 °C. The surface area performed by BET showing an increasing from 213 m2/g to 224 m2/g on ZnAl LDH. Carbonate anions were confirmed by FT-IR result which are at 1390 cm-1 and 856 cm-1. 1 wt% of calcined ZnAl LDH catalyst has been used in the transesterification reaction using waste cooking oil (WCO). The compositions of biodiesel that has been detected using GC-FID are laurate, myristate, palmitate, linoleate, and stearate.

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.

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.
