Abstract: Embodiments of methods for converting gas condensate into a product stream comprising propylene comprise feeding gas condensate at a top region of a downflow high severity fluidized catalytic cracking reactor (HSFCC), where the gas condensate comprises: at least 50% by weight paraffins, and less than 0.1% by weight olefins. The method further comprises feeding catalyst to the top region of the downflow HSFCC reactor in an amount characterized by a catalyst to gas condensate weight ratio of about 5:1 to about 40:1, where the catalyst comprises nano-ZSM-5 zeolite catalyst having an average particle diameter from 0.01 to 0.2 ?m, a Si/Al molar ratio from 20 to 40, and a surface area of at least 20 cm2/g. The method further comprises cracking the gas condensate in the presence of the catalyst at a reaction temperature of about 500° C. to about 700° C. to produce the product stream comprising propylene.
