Novel Coke Shift Matrix Technique to Enhance the Activity of the Secondary Reaction Zone in MIP-CGP Process

摘要

In response to the world trend of environment protection,the gasoline quality in China is also improved,which requires the content of olefines in gasoline pool less than 18.%.Since the gasoline blending components of China are composed mostly of FCC naphtha with only a low share of reformate,alkylate and etc.Gasoline pool has an excessively high olefin contents (40－65.% in China).In addition,the need of propylene is continuously increasing.Therefore,much effort is focusing on improving FCC process to produce clean gasoline and more propylene simultaneously.
