摘　　要：Co Mo系耐硫低变催化剂含有碱金属钾,使用过程中容易硫酸盐化而失活。本实验所制备的新型全低变催化剂使用锌铝尖晶石载体,不采用钾作为助剂。试验结果表明,该类催化剂的活性、脱氧性能达到QCS 02及QCS 02 T的水平。中试放大并工业应用成功。The common Co-Mo-K sulfur-tolerant shift catalysts loses its activity quickly because the alkali metal potassium in catalyst promotes the formation of sulfate easily. New catalyst used ZnAlO_4 as support and potassium was not needed. The results showed that the water-gas shift activity and deoxygenizing activity were the same as commercial catalysts QCS-02 and QCS-02-T, respectively. This new catalyst has been used in industry successfully.
