THEORETICAL INNOVATION AND PRACTICE APPLICATION OF HYDROCRACKING TECHNOLOGY

Abstract

Abstract: SINOPEC (Dalian) Petrochemical Research Institute Co., Ltd. (FRIPP) found that the induced dipole moment of hydrocarbon molecule and the stability of the reaction intermediate carbocation were key factors that affected the adsorption and reaction of hydrocarbon molecule. On this basis, the gradual reaction theory was proposed to guide the development and upgrading of hydrocracking processes and catalytic materials. The application of the gradual reaction theory avoided the occurrence of low-efficient and disorderly reactions and made the hydrocracking process reasonally and orderly, thus, the product selectivity and quality of the hydrocracking process were improved under the reaction environment of low energy consumption and low hydrogen consumption. The gradual reaction theory will effectively promote the refinery configuration adjustment in China, to achieve a reasonal and orderly "oil to chemicals" and "oil to special oil products" transformation and development.

Key words: hydrocracking, gradual reaction, adsorption, catalytic reaction, upgrade
