FORMATION AND CONTROL OF DRY GAS IN CATALYTIC CRACKING REACTION

摘要

For many refiners, fluid catalytic cracking unit is the key to profitability in that the successful operation of the unit detennines whether or not the refiner can remain competitive in today's market. To improve the utilization rate of hydrogen resource containing feedstock, the ultimate objective of catalytic cracking reaction is to transfer hydrogen from feedstock to desired products as much as possible.
