Partial oxidation reformer-reforming exchanger arrangement

摘要

Disclosed are a process for preparing syngas, an apparatus for producing syngas and syngas prepared by the said process. The process comprises partially oxidizing a first hydrocarbon portion with oxygen in a partial oxidation reactor to produce a first reactor effluent; cooling the first reactor effluent to a temperature between 650°C and 1000°C; supplying the first reactor effluent to a reforming exchanger; passing a second hydrocarbon portion with steam through a catalyst zone in the reforming exchanger to form a second reactor effluent; discharging the second reactor effluent from the catalyst zone to form an admixture with the first reactor effluent; passing the admixture across the catalyst zone in indirect heat exchange therewith to cool the admixture and heat the catalyst zone; collecting the cooled admixture from the reforming exchanger.
