Abstract
A series of K modified coppercobalt based catalysts were prepared using step by step continuous coprecipitation method, and the catalytic performance of the catalysts was investigated. The experimental results showed that the catalyst exhibited the best activity, CO conversion, the yield of C₂+OH in liquid products and the mass fraction of C₂+OH was 65.74%,0.062 g·(mL·h)-I and 18.95%, respectively, under the condition as follows: mass ratio of cobalt to copper 1:1, K₂CO₃ loading mass fraction 1%, pH=7.2 and reaction temperature 310 ℃.
