Abstract
Official abstract text for this publication.
A carbon oxides conversion process includes reacting a carbon oxide containing process gas containing hydrogen and/or steam and containing at least one of hydrogen and carbon monoxide in the presence of a catalyst including shaped units formed from a reduced and passivated catalyst powder, the powder including copper in the range 10-80% by weight, zinc oxide in the range 20-90% by weight, alumina in the range 5-60% by weight and optionally one or more oxidic promoter compounds selected from compounds of Mg, Cr, Mn, V, Ti, Zr, Ta, Mo, W, Si and rare earths in the range 0.01-10% by weight, wherein said shaped units have a reduced to as-made mean horizontal crush strength ratio of ≧0.5:1 and a copper surface area above 60 m 2 /g Cu.
First claim
Opening claim text (preview).
The invention claimed is: 1. A catalyst suitable for use in carbon oxides conversion reactions in the form of a pellet formed by compression of a reduced and passivated catalyst powder, said catalyst powder comprising copper in the range 10-80% by weight, zinc oxide in the range 20-90% by weight, alumina in the range 5-60% by weight and optionally one or more oxidic promoter compounds selected from the group consisting of compounds of Mg, Cr, Mn, V, Ti, Zr, Ta, Mo, W, Si and rare e…
