Catalytic cracking process of a lipid-containing feedstock

Abstract

A process for catalytic cracking of a lipid-containing feedstock is provided. The lipid-containing feedstock contains lipids derived from a diatomic microalgae species. The lipid-containing feedstock is contacted with at least one cracking catalyst at a temperature of at least 450° C., to obtain a product stream; and separating at least one hydrocarbon fraction from the product stream.
