Process for providing synthesis gas and for producing methanol

Abstract

The present invention proposes a process for producing synthesis gas, in particular synthesis gas for methanol synthesis. The process includes the steps of providing a sulfur-containing hydrocarbon stream; providing an electrolytically produced hydrogen stream; supplying a portion of the electrolytically produced hydrogen stream to at least a portion of the sulfur-containing hydrocarbon stream to obtain a hydrogen-enriched sulfur-containing hydrocarbon stream; desulfurizing the stream obtained according to step (c) in a hydrodesulfurization unit (HDS unit) to obtain a sulfur-free hydrocarbon stream; supplying a portion of the electrolytically produced hydrogen stream to at least a portion of the stream obtained according to step (d) to obtain a hydrogen-enriched sulfur-free hydrocarbon stream and converting at least a portion of the stream obtained according to step (e) into a synthesis gas stream in the presence of oxygen as oxidant in a reforming step.
