Catalytic reforming process description

D. M. Litde, Catalytic Reforming, Perm Well Books, Tulsa, OHa., 1985. Refs. 38, 41, 42, and 56 contain excellent descriptions of benzene manufacturing processes. 

Description The catalytic-steam hydrocarbon reforming process produces raw synthesis gas by steam reforming in a heat exchange-based system under pressure based on the Kellogg Brown Root Reforming Exchange System (KRES). 

Catalytic reforming models developed by Kmak and Ramage et al. give a fairly detailed description of the process. In Powell s hydrocracking modeP, the chemical composition parameters are continuous functions of carbon numbers. Quann and Krambeck developed a kinetic model for olefin oligomerization over the ZSM-5 catalyst. 

Description Gas feedstock is compressed (if required), desulfurized (1) and sent to the optional saturator (2) where some process steam is generated. The saturator is used where maximum water recovery is important. Further process steam is added, and the mixture is preheated and sent to the pre-reformer (3), using the Catalytic-Rich-Gas process. Steam raised in the methanol converter is added, along with available C02, and the partially reformed mixture is preheated and sent to the reformer (4). High-grade heat in the reformed gas is recovered as high-pressure steam (5), boiler feedwater preheat, and for reboil heat in the distillation system (6). The high-pressure steam is used to drive the main compressors in the plant.
