FCC catalyst deactivation studies to mimic refinery conditions for high-propylene applications

The fluid catalytic cracking unit (FCCU) is a conversion unit located at the heart of many refineries. Its main purpose is to crack crude oil-derived feedstocks into valuable liquid products, primarily LPGs (propylene and butylenes), and gasoline and light-cycle oil (LCO) precursors. The process uses a fluidizable catalyst, comprising an alumina-silica framework and tailored for each refinery to meet its specific needs. Often, the changing of a catalyst includes catalyst testing evaluations, employed by about 50% of the FCCUs in the world. The testing process is cumbersome, in which multiple methods are available to refineries.

New catalyst increases FCC olefin yields

The new catalyst helped enable the refinery to maximize propylene and isobutylene yields, expand total LPG production, maintain LCN yield, improve bottoms upgrading and expand the FCCU operating window.
