The catalyst decay theory of Wojciechowski (1) is applied to a simplified theoretical mechanism of catalytic gas oil cracking. The resulting patterns of selectivity are presented and general conclusions drawn. It is shown that selectivity in gas oil cracking is bounded by optimum and minimum performance envelopes which confine the range of possible product distributions.
