Steam 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). Syngas reacts further to give more hydrogen and carbon dioxide in the reactor. The carbon oxides are removed before use by means of pressure swing adsorption (PS… factory refurbished mac laptopsWebSteam Methane Reforming, or SMR, processes feedstocks, ranging from natural gas to light naphtha, mixed with steam to produce a hydrogen-rich syngas effluent, with a typical H2/CO ratio of 3:1 to 5:1.
