| 简介 |
FIELD : chemistry.
SUBSTANCE : invention relates to catalyst, suitable to application in reactions of conversion of carbon oxides, in form of granules, formed by pressing reduced and passivated catalyst powder, and claimed powder contains copper in the interval 10-80 wt %, zinc oxide in the interval 20-90 wt %, aluminium oxide in the interval 5-60 wt % and, optionally, one or several oxide promoter compounds, selected from compounds of Mg, Cr, Mn, V, Ti, Zr, Ta, Mo, W, Si and rare-earth elements, in quantity in the interval 0.01-10 wt %. Said granules have average crush strength in horizontal direction after production ≥6.5 kg, ratio of values of average crush strength in horizontal direction after reduction and after production ≥0.5 : 1 and area of copper surface over 60 m2/g Cu. Invention also relates to method of claimed catalyst production and to method of conversion of carbon oxides in presence of claimed catalyst.
EFFECT : catalyst has high strength of granules and high activity as a result of increased area of copper surface, which makes it possible to apply reactors of smaller size and increase process productivity.
