Steam Reforming
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 (PSA) with molecular sieves for the final purification. The PSA works by adsorbing all impurities from the syngas stream to leave a pure hydrogen gas.

Famous quotes containing the words steam and/or reforming:
“Wisely watch for the sight
Of the supernova burgeoning over the barn,
Lampshine blurred in the steam of beasts, the spirit’s right
Oasis, light incarnate.”
—Richard Wilbur (b. 1921)
“The science of constructing a commonwealth, or renovating it, or reforming it, is, like every other experimental science, not to be taught a priori. Nor is it a short experience that can instruct us in that practical science, because the real effects of moral causes are not always immediate.”
—Edmund Burke (1729–1797)
