中文摘要：
引言 纳米镍催化剂在有机物如苯、硝基苯、对硝基苯酚等的催化加氢和2-丁醇的催化脱氢等方面有着广泛的应用[1-4].有文献报道[5-7],悬浮态非负载型催化剂的催化活性高于负载型催化剂.使用悬浮态的纳米催化剂可大大提高反应速率,降低催化剂的使用量,这对提高催化剂的使用效率,降低生产成本,增加生产效益是很有价值的.
英文摘要：
Ceramic membranes were used to recover nanometer nickel catalyst in the preparation of paminophenol. In order to resolve the problem inert particles were added to the su oxides was proven to be effective. of adsorption loss of nanometer nickel in the pilot plant, spension. As a result, adding inert particles such as micro or submicro They could alleviate the adsorption loss of nanometer nickel particles and shorten the time of reaching steady state of nickel concentration without affecting the activity of the catalyst and permeate flux.
