FIELD: technological processes. ^ SUBSTANCE: invention relates to a technology of catalysts preparation for conversion of natural gas and may be used in chemical industry, for instance, to produce technical hydrogen. The method is described to prepare a catalyst for natural gas conversion, including treatment of aluminium oxide in presence of potassium hydroxide, production of a homogeneous paste, forming granules from it, their curing, drying and baking, impregnation of the produced carrier in solutions of nickel and aluminium nitrates with subsequent drying and curing, at the same time combined grinding and mixing pf aluminium oxide is carried out with solid potassium hydroxide for 45-60 min with subsequent addition of water to the mixture, baking of granules prior to carrier impregnation is carried out at the temperature of 1200-1250C for 4-6 hrs, and potassium hydroxide is used in amount of 2-5% from the initial raw materials weight. ^ EFFECT: reduced energy intensity of the method and increased activity of the finished catalyst at temperature that corresponds to the start of the steam conversion process. ^ 1 tbl, 2 ex |
