CARBON OXIDES CONVERSION PROCESS

摘要

596845 A carbon oxides conversion process is described, which comprises 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 comprising shaped units formed from a reduced and passivated catalyst powder said powder comprising copper in the range 15 70 % by weight, zinc oxide wherein the weight ratio of Cu:Zn expressed as oxide is ?1:1, 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 60m2/g Cu.
