摘　　要：采用完全液相法制备了Cu/Zn/Al浆状催化剂,考察了胶溶剂HNO3用量对催化性能的影响。结果表明,适量的胶溶剂HNO3用量可以减小Cu0晶粒度,提高催化剂的活性;胶溶剂的用量可以改变催化剂各组分之间的相互作用,过多的HNO3会导致催化剂活性的降低。Cu/Zn/A1 slurry catalysts were prepared by complete liquid-phase technology with nitric acid as peptizator. The effect of varying the amount of the peptizator on the catalyst was investigated. The re- sults indicated that the catalysts have smaller CU° grain size and high activity with increasing nitric acid dosage. At the same time nitric acid dosage can also change the interaction between elements in the pre- cursors, but exceeding dosage of nitric acid dosage will reduce the activity of the ealalyst.
