PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS

摘要

Process for the production of synthesis gas with an increased H2/CO-ratio from normally gaseous hydrocarbons comprising the following steps: a) at least one normally gaseous hydrocarbon is converted into a synthesis gas comprising H2 and CO by partial oxidation with an oxygen-containing gas; b) at least one normally gaseous hydrocarbon is converted with steam into a gaseous mixture comprising H2 and CO; c) the gaseous mixture comprising H2 and CO, formed in step (b) is separated into a CO-containing stream and a H2 stream; d) the H2/CO-ratio of the synthesis gas produced in step (a) is increased by adding at least part of the H2 stream obtained in step (c) thereto.
