Abstract

A method of repurposing a fluid catalytic cracking (FCC) system originally designed for cracking vacuum gas oil (VGO) may include generating a first mixture of a renewable lipid feedstock and a particulate catalyst. The first mixture may be flowed through a riser for a sufficient time for the particulate catalyst to promote partial reaction of the renewable lipid feedstock to generate a second mixture including (i) catalyst particles to which acidic reaction intermediates are sorbed and (ii) a vapor-phase intermediate composition which is essentially acid free. The second mixture may be flowed into a reactor/stripper which is partially filled with more particulate catalyst. Within the reactor/stripper, the second mixture may be contacted with particulate catalyst for a sufficient residence time for the acidic reaction intermediates to substantially completely react to generate additional vapor-phase intermediate composition. The vapor-phase intermediate composition may be disengaged from the particulate catalyst and collected.
