METHOD OF PREPARING CATALYST FOR MIDDLE-TEMPERATURE STEAM-MEDIATED CONVERSION OF CARBON MONOXIDE

摘要

FIELD: carbon monoxide conversion catalysts.;SUBSTANCE: invention relates to a method of preparing catalysts for middle-temperature conversion of carbon monoxide, which can be used in industry when producing nitrogen-hydrogen mix for ammonia synthesis. Preparation of catalyst for middle-temperature conversion of carbon monoxide with water steam, comprising precipitation of iron hydroxide from iron nitrate solution with ammonia-containing solvent, washing of iron hydroxide with water to remove nitrate ions, mixing with calcium and copper ions, mechanical activation of components, molding, drying, and calcination of granules, is characterized by that, in the component mixing step, lanthanum oxide is supplementary added, in which case molar ratio of components is as follows: Fe₂O₃/CaO/CuO/La₂O₃ = 1:(0.8-0.9):(0.045-0.08):(0.005-0.01).;EFFECT: increased catalytic activity and more than thrice reduced content of by-products in condensate.;1 tbl, 3 ex
