Abstract

The work is aimed at establishing the thermodynamic, kinetic and hydrodynamic regularities of the vacuum gas oil catalytic cracking and the zeolite-containing catalysts regeneration, which served as a catalytic cracking reactor mathematical model development basis. The prediction calculations ensured the catalyst circulation ratio optimization depending on the catalyst flow temperature after regeneration. To maintain the gasoline fraction maximum yield (58.47 and 58.38 wt%) it is necessary to keep the catalyst circulation ratio at the level of 6 and 9.5 tonscat/tonsfeed if the catalyst flow temperature after regeneration are 700 and 650 °C, respectively.
