Abstract

A process for fluid catalytic cracking of a feedstock composition is disclosed. The process comprises contacting the feedstock composition with a fluid catalytic cracking catalyst composition under fluid catalytic cracking conditions. The feedstock composition comprises one or more oxygen-containing organic compounds, wherein oxygen is present in the feedstock composition in an amount of greater than 0.2 wt.% to 50 wt.% or less based on a weight of the feedstock composition. The fluid catalytic cracking catalyst composition comprises a first particle comprising fluid catalytic cracking catalyst in an amount of from 50 wt.% or more to 99.5 wt.% or less based on a weight of the fluid catalytic cracking catalyst composition and a second particle comprising a deoxygenation additive comprising a Lewis Acid-containing component in an amount of from 0.5 wt.% or more to 50 wt.% or less based on the weight of the fluid catalytic cracking catalyst composition.
