The optimum location of the zeolite component in a silica-alumina matrix is calculated for various levels of catalyst deactivation such that gasoline selectivity from gas-oil is maximized at each deactivation level. Results when the composite cracking catalyst is uniformly deactivated are compared with those when deactivation is nonuniform. In both cases, the maximum selectivity first increases with increasing deactivation level, and then decreases. The maximum selectivity is not qualitatively altered in moving from uniform to nonuniform deactivation. However, the optimum location of the zeolite required to achieve this maximum selectivity is different in the two cases. |
