CATALYST FOR VAPOUR CONVERSION OF CARBON MONOXIDE METHODS FOR THE PRODUCTION AND FOR THE USE THEREOF

The invention relates to producing hydrogen by means of the vapour conversion of carbon monoxide and a catalyst for said process and can be used in different industries. The invention discloses an iron-chromium catalyst containing an iron-chromium hydroxyl compound phase having a goethite and/or hydrohematite structure, a method for the preparation thereof and a method for the use thereof in a process for the vapour conversion of carbon monoxide. The catalyst can also contain copper. The catalyst is obtainable by precipitating sodium and potassium, by means on solutions of carbonates or ammonia hydroxides, from solutions of mixture of iron 2+ and 3+ and chromium 3+ nitrates which are obtained by the oxidation-reduction interaction of metal iron, chromium 6+ compounds and nitric acid. A process for the vapour conversion of carbon monoxide using said catalyst according to the inventive method is carried out at a temperature greater than 250° C. Said invention makes it possible to produce a catalyst having low sulphur (equal to or less than 0.03 mass %) and chromium 6+ (equal to or less than 0.05 mass %) contents and exhibiting a high activity at temperatures of 350° C. and less.
