2020 CATALYST HANDBOOK INDUSTRY CATEGORIES PROCESS CATEGORIES COMPANY INDEX REFINING FCC SCT Series TABLE 1. Comparison of SCT Series catalyst and base catalyst parameters Feed type Base catalyst SCT Series catalyst DSVGO DSVGO Application: FCC catalyst for gas oil, featuring high gasoline and LCO selectivity with superior coke selectivity. Total feed rate Maximum Maximum Air rate to regenerator Maximum Maximum Description: * For use in the FCC unit * Based on a combination of high-performance USY zeolite and JGC Catalysts and Chemicals Ltd. proprietary matrix technology, CMT * Optimized with CMT-70 for high bottom cracking * Applicable in a catalyst circulation-limited and/or wet gas capacity-limited FCC unit. ROT Base Maximum Catalyst-to-oil ratio Base +0.7 Catalyst addition rate Base Maximum LPG + gasoline Base +0.9 vol% LCO Base +0.1 vol% CLO Base -0.6 vol% Total liquid volume Base +0.4 vol% Advantages: The SCT Series achieves high bottoms conversion and high gasoline and LCO yields (Table 1). It also enhances light olefins (C3= and C4=) selectivity due to high matrix activity (Fig. 1). Other advantages are listed in the table. Economics: In the use of the SCT Series, the slurry viscosity can be reduced due to more cracked side-chains of heavy hydrocarbons.
