Description:
Fluid Cracking Catalysts (FCC) have been modified by Advanced Catalyst Technology (ACT) treatment systems to increase conversion to high value transportation fuels, reduce production of coke, hydrogen, dry gas, and heavy cycle oil, and increase catalysts’ resistance to hydrothermal deactivation. ACT has been successfully applied to a wide variety of equilibrium and fresh catalysts. Micro-Activity (MAT) results at constant conditions show typical increase of gasoline selectivities over lo%, and typical decreases of coke factors over 50%, hydrogen factors over 50%, and gas factors over 50%. MAT results are further supported by detailed surface area and pore volume analyses which show that ACT treated catalysts have improved surface area and micropore volume retention providing improved accessibility to and from active acid sites, thus reducing hard (- catalytic) coke, and soft (- strippable) coke. ACT systems can improve FCCU and RFCCU economics for units which are limited by coke make, delta coke, regenerator temperature, dry gas production, or conversion, and by increasing gasoline selectivity, reducing bottoms production and fresh catalyst consumption. Payouts for all systems evaluated have been less than one year. Conversion can be significantly increased while maintaining the same coke make, or feed rate increased to the same coke limit. ACT systems have shown significant improvements for all catalysts tested. Benefits are shown for a wide range of catalysts from gas oil and resid units with figures showing ACT systems better than existing systems due to increased LPG+Gasoline+LCO versus conversion, dry gas, and coke.
