Concentration of biopetrol synthesized from oleic acid through heterogeneous catalytic cracking using zeolite as catalyst

One of the main fatty acids in vegetable oil is oleic acid and it has the potential to replace petroleum fuels in the future.In this research,zeolite catalysts are used over the conversion of oleic acid into isooctane as the future biopetrol in a heating mantle at atmospheric pressure. The main purposed of studies is to improve the concentration of isooctane using heterogeneous catalytic cracking method with using 20g of zeolite catalysts.The effect of various rotation speed of sample at 600 rpm,780 rpm,960 rpm and 1140 rpm and dilution factor of isooctane to hexane at 10% are studied over the yield of biopetrol at 98oC. Gas chromatography is used for the qualitative and quantitative analysis of the samples.Backward calculation is applied to calculate the actual concentration of isooctane in the distilled oleic acid.The maximum yield of desired isooctane obtained at 1140 rpm with 20g of catalyst and dilution of 10% isooctane to hexane is recorded at 11.67 %.Experimental works has successful show that heterogeneous catalytic cracking is greater in conversion than catalytic cracking (static catalyst)and thermal cracking
