| 摘 要： | 采用两段式焙烧制备氧化铝载体,饱和浸渍法制备负载量相同的Mo-Co催化剂,通过BET、XRD、SEM、FT-IR、TPR对氧化铝载体和催化剂表征。预焙烧阶段通入不同量的空气,考察气剂体积比对氧化铝载体物化性质及催化剂性能的影响。结果表明,调节两段式焙烧的预焙烧过程气剂体积比可调变载体孔分布,气剂体积比为800时,原料油加氢脱硫转化率最高为48.7%。

| Abstract: | Mo-Co catalyst with same Mo and Co load was prepared by saturated impregnation with two stages roasting and characterized by BET,XRD,FT-IR and TPR.Effects of air on physicochemical properties of alumina carrier and properties of catalysts were investigated by changing volume ratio of air to in the pre-roasting stage.Results showed that change volume ratio of air to catalyst in pre-roasting could adjust pore size distribution.When volume ratio of air to catalyst was 800,desulfurization of raw oil was 48.7%. |

| Keywords: | catalyst engineering alumina carrier roasting volume ratio of air to catalyst Mo-Co Catalyst desulfurization activity |
