Abstract: This article consists of two parts.In the first part,factors affecting the saturation carrying capacity of particles and the average bed density are discussed.Based on test data from several commercial FCC units,a new correlation of the saturation carrying capacity is recommended and a new equation of average bed density is suggested.In the second part,various factors affecting the catalytic conversion of feed stocks are reviewed.Based on extensive experimental data,a new correlation has been proposed by which the change of performance of a FCC plant from existing operating conditions and feedstock composition to different conditions and/or feedstock composition can be predicted.
