HOW CAN WE INCREASE THE LCO YIELD AND QUALITY IN THE FCC:CRACKING PATHWAYS ANALYSIS

摘要

The catalytic cracking mechanism has been largely studied and the main reactions accompanying have been well identified through the cracking of small model molecules.Nevertheless,the simulation of the reactivity of complex mixtures,like a typical vacuum gasoil FCC feed,coupled with the particular heat balanced operation of FCCU is not easy.Such detailed models are now of great interest as they are able to bring information not only on main product yields but also on products quality [1-3].
