Recently the value of LPG in chemical operations downstream of the FCC unit has increased. Such downstream operations utilize propylene not only in alkylate, but also in rapid growth petrochemical applications such as for a raw material in the manufacture of polypropylene and propylene oxide. Isobutane and the butenes (particularly butene-2 in sulfuric acid catalyzed alkylation units) are prized for alkylate feed. The profit potential and incentives to use other LPG components such as isobutene to make MTBE is now increased because of legislative actions and increased octane performance demand; and because of the greater isobutene content in the LPG from the new FCC octane catalysts. A low non-framework alumina (NFA) zeolite studied made a more olefinic LPG with higher iso-to normal C4 ratio than the other zeolites. Pilot plant data has also shown the new low NFA zeolite gave not only outstanding motor octane (MON) performance, but produced an LPG with better propylene to propane ratio, more isobutene, more n-butenes and more C4 branching than other RE promoted zeolite catalysts. Commercial results have verified the improved performance and profitability for the new low-NFA type zeolite catalysts. Three commercial examples are described.
