用溶胶-凝胶法制备了Co-Cu/SiO2系列的担载型催化剂,采用SBET、TPR、XRD、O2滴定等技术对该催化剂进行了研究,并考察了催化剂在F-T合成反应中的催化性能.结果表明,样品的SBET较大,Co和Cu组分均很好分散;Cu2+的加入使得Co更易于被氢气还原,Co是经由Co3+→Co2+→Co0的还原过程,Cu的还原为Cu2+→Cu0;Cu2+的引入使得样品中钴的还原度增大,对F-T合成的催化性能有了一定的改善. The supported catalysts of Co-Cu / SiO2 series were prepared by sol-gel method. The catalysts were studied by SBET, TPR, XRD and O2 titration. The catalytic performance of the catalyst in FT synthesis was also investigated The results show that the SBET of the sample is relatively large, and the Co and Cu components are well dispersed. The addition of Cu2 + makes Co easier to be reduced by hydrogen, and the reduction of Co is Cu2 + → Cu0 through the reduction of Co3 + → Co2 + → Co0 ; The introduction of Cu2 + makes the reduction of cobalt in the sample increased, which has a certain improvement on the catalytic performance of FT synthesis.
