摘要：

An investigation of the catalytic cracking of crude oils on modified zeolite aluminosilicate catalysts was presented. The kinetics of cracking of the crude oil cut on this catalyst, the coke deposition, and subsequent regeneration in air current were also investigated and compared to the kinetic equations of these processes. After blowing the rector through with nitrogen and reducing the temperature to the given level, cracking was conducted for 30 min. It was found that the AMCS grafted to the surface of the catalyst increases its activity and stability during cracking, as well as the rate of burning coke from the surface of the coked catalyst.
