Dry reforming vs steam reforming
WebA process for producing syngas including at least H2 and CO. The process includes the steps of a) generating a transition metal carbide by reacting a corresponding transition metal oxide with a fuel to produce a stream of syngas; and b) combining the transition metal carbide with oxygen to oxidize the transition metal carbide to regenerate the … WebSteam reforming (SR), sometimes referred to as steam methane reforming (SMR) uses an external source of hot gas to heat tubes in which a catalytic reaction takes place that converts steam and lighter hydrocarbons such as methane, biogas or refinery feedstock into hydrogen and carbon monoxide (syngas).
