镨和铈对低温还原法制备的ni2p催化剂加氢脱硫活性的影响
, PP. 1128-1133
Keywords: 次磷酸盐,低温热解,ni2p,加氢脱硫,二苯并噻吩,镨,铈
Abstract:
？采用低温热解次磷酸盐法制备了ni2p-l、pr-ni2p-l和ce-ni2p-l催化剂,并采用xrd、h2-tpr、bet、co吸附、xps等手段对制备得到的催化剂进行了表征。以二苯并噻吩(dbt)为模型化合物,研究了pr、ce稀土元素对低温还原法制备的ni2p-l催化剂加氢脱硫(hds)性能的影响。结果表明,催化剂添加稀土pr和ce能够抑制ni5p4和其他杂晶的生成,从而促进活性相ni2p的生成;添加稀土能提高催化剂对联苯(bp)的选择性,但催化剂的总hds活性略有降低。
