Title
Comparison of induction behavior of Co/CNT and Co/SiO2 catalysts for the Fischer-Tropsch synthesis
Abstract

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.

►The induction period lasts over 26 h on Co/SiO2 while less than 10 h on Co/CNT. ►In induction period, temperature on Co/CNT is stable compared with Co/SiO2. ►Co/CNT shows enhanced FTS catalytic activity and stability at steady state.
