2020 CATALYST HANDBOOK INDUSTRY CATEGORIES PROCESS CATEGORIES COMPANY INDEX REFINING FCC Application: The ZMX-B-HP additive cracks low-octane, mid-to-heavy-range gasoline and light LCO hydrocarbons to LPG with high selectivity to C4 olefins. Description: ZMX-B-HP is a zeolite-based additive suitable for refiners requiring C4-rich LPG olefins stream for alkylation or etherification (ETBE) downstream of the FCC. Increasing the proportion of C4 vs. C3 olefins in alkylate feed improves its octane. Advantages: ZMX-BHP provides flexibility to increase light olefins yields for alkylation and etherification to improve gasoline octane, with high selectivity to C4 olefins (Fig. 1).
