ABSTRACT:
This invention is to a method and system for operating a hydrocarbon conversion process. A two stage reactor system is used in which the gas superficial velocity of the second reaction stage is greater than that in the first reaction stage. The first reaction stage operates at more continuous stirred tank reactor (CSTR) like characteristics, and the second reaction stage operates at more plug flow reactor (PFR) like characteristics.
