摘要：
Carbon nanotubes and silica gel supported cobalt catalysts (Co/CNT and Co/SiO2) for Fischer-Tropsch (FTS) synthesis with syngas as feedstock were prepared. The catalysts were characterized by TPR, BET, and TEM. Effect of support material on induction period of FTS was investigated. Results showed that, there was a remarkable induction period about 26 h and very fluctuating temperature at the initial reaction stage for Co/SiO2 catalyst. The catalytic performances for FTS changed notably during the induction period. CNTs as supported material could remarkably shorten the time of induction period as well as promote the catalytic activity and stability for FTS. (C) 2012 Elsevier B.V. All rights reserved.
