Adsorption and solid catalysed reaction between activated carbon impregnated with SnO2 and CO at ordinary temperature

We have used pressure swing adsorption (PSA) measurements to study the reaction of CO adsorbed from H 2/CO (75/25vol.%) onto an activated carbon-tin(IV) oxide (AC-SnO 2 ) catalyst to form gaseous CO...
