METHOD AND APPARATUS FOR PRODUCING SYNTHESIS GAS

摘要

A method of producing synthesis gas includes directing a first flow of hot synthesis gas through a first conduit, and directing a second flow of feed gas through at least one second conduit. The second conduit contains a reforming catalyst. The feed gas includes a mixture of steam and a hydrocarbon gas. The second conduit has an outer surface in contact with the hot synthesis gas. Heat from the hot synthesis gas is transferred across the second conduit to the feed gas thereby heating the feed gas and cooling the hot synthesis gas. The heated feed gas contacts the reforming catalyst and undergoes a reforming reaction that produces a third flow of synthesis gas.
