摘要: A method of forming a biodiesel product and heterogeneous catalyst system used to form said that has high tolerance for the presence water free fatty acids (FFA) in oil feedstock is disclosed. This may simultaneously catalyze both esterification FAA transesterification triglycerides present feedstock. The according one aspect disclosure represents class zinc lanthanum oxide catalysts include different ratios oxides (Zn:La ratio) ranging from about 10:0 0:10. Zn:La ratio believed have an effect on number reactivity Lewis acid base sites, as well glycehdes, acids, hydrolysis glycehdes biodiesel.
