Return to Russian/Soviet Patent Table of Contents An Iron Catalyst
Abstract An iron catalyst is suggested for hydrogenation of the O2, CO and CO2 impurities in hydrogen-containing gases, consisting of iron oxide with alumina and silica additives. To increase the catalyst activity and stability, the components are taken in the following ratio (wt.%): iron oxide 94.5-92.0, alumina 3.0-4.0, silica 1.0-2.0, magnesium oxide or lithium oxide 1.5-2.0. Iron catalyst of the proposed composition allows the decrease of carbon monoxide content in hydrogen-containing gas from 0.3% to residual concentration of 5-10 cm3/m3 at a temperature of 200-280°C and gas flow space velocity of 30000 hr-1. |
