Title:

MANUFACTURE OF GAS FLOW CONTAINING HYDROGEN AND CARBON OXIDES AND APPARATUS THEREFOR

Document Type and Number:

Japanese Patent JPS61222903

Kind Code:

A

Abstract:

Hydrocarbon steam reforming process and apparatus wherein blind ended, ie double pass, externally heated reformer tubes (52) are employed. The inner, ie return, tubes (80) are insulated so that there is only a small temperature drop between the reacted gas leaving the catalyst zone (90) and entering the return tubes (80) and the gas leaving the return tubes (80). The outer, blind-end, tubes (52) preferably have fins (54) and are surrounded by sheaths (56) through which the heating medium passes. The heating medium is preferably hot gas obtained by subjecting the primary reformed gas to secondary reforming.
