Abstract: With REF-SIM kinetics reaction model of continuous catalytic reforming (CCR) and Petro-SIM process simulation software, a new index, R (A/(N+P)), of feed properties associated with unit energy consumption was proposed based on the analysis of reforming reaction process and mathematical regression method. It shows a good correlation between the new feed index R and unit energy consumption, better than that of the conventional feed index, potential aromatic content or aromatization index. Under the same octane requirement of product, the new feed index R can be used as a basic evaluation parameter when benchmarking energy consumption of different CCR units.
