摘要：

The results of a simple model of vacuum gasoil cracking are presented: the radial profiles of superficial gas velocity, solid concentrations and axial profiles of conversion and yields are predicted by a plug flow model with a gas velocity profile and a radial dispersion coefficient. The catalyst to gas slip coefficient is fitted to industrial results. The core annulus structure of the bed results in a substantial reduction of gasoline yield.
