摘要：
A new method for the preparation of catalysts for the Fischer-Tropsch synthesis is proposed; it consists in the deposition of cobalt metal on a support at the instant of reduction from salts with a solution of NaBH4. The catalysts thus prepared are stable in air, and they do not require further high-temperature activation by hydrogen. The specific rate of CO conversion was 3.4-3.7 mol(CO) mol(-1) (Co) h(-1); the selectivity for higher hydrocarbons was up to 88 mol %, and the hydrocarbon chain growth index alpha was up to 0.87.
