CHARACTERISTICS OF CRACKING OF KEROSENE-GASOIL CUT AND ATMOSPHERIC RESID BLENDS

摘要

Catalytic refining of heavy cuts is an important direction in increasing takeoff of light cuts with an increase in the total volume of heavy crude produced.The most highly productive of these processes is catalytic cracking in the continuous-flow or microsecond mode.Atmospheric resid or blends of atmospheric resid and kerosene-gasoil cut or vacuum gasoil in a given ratio can be used as feedstock for such processes.Not only the process conditions but also the type and chemical composition of the catalyst must be selected for optimizing catalytic cracking of this feedstock.
