Heterogeneous Catalytic Modified Process in the Production of Biodiesel from Sunflower Oil, Waste Cooking Oil and Olive Oil by Transesterification Method

Using transesterifiction of sunflower oil, olive oil and waste cooking oil with methanol and heterogeneous catalyst made by clinoptilolite, biodiesel was obtained. With molar ratio of alcohol to oil 1:7 and mentioned catalyst (3 wt%), yield of biodiesel from sunflower oil, cooking waste oil and olive oil were: 97%, 95% & 92% respectively. SEM images showed the average particle sizeof 342.44 nm. FTIR spectrum showedno impurity in produced biodiesel. The products were compared to the consuming Petro-dieselin Tehran according ASTM standard cloud point, pour point, freezing point, cetane number, iodine value, saponification number, heating value, acid value, viscosity, density andflash point.
