英文摘要 | Coal pyrolysis can be significantly affected by CoCl2 catalyst. In this paper, the effect of CoCl2 catalyst on the pyrolysis of Huolinhe lignite was investigated in a spout-entrainment reactor and in a thermogravimetric cell. The results showed that the yield of total volatile from lignite fast pyrolysis using CoCl2 catalyst was twice as much as that without CoCl2 catalyst. Moreover, the main components of light tar, including phenol, carboxylic and aliphatic groups were also increased by 150 %, 83 %, 100 % and 200 %, respectively. On the contrary, the slow pyrolysis of lignite was inhibited by CoCl2 catalyst: the yield of total volatile and the yields of phenol and carboxylic groups were all decreased. The different effect of CoCl2 catalyst on fast and slow pyrolysis of coal might be attributed to secondary cracking of tar precursors. In order to recycle Co catalyst, CoCl2 was impregnated to clay zeolite. The catalytic effect of Co-clay zeolite is lower than that of CoCl2 directly impregnated to lignite. However, catalytic pyrolysis of lignite with Co-clay zeolite should be feasible in an industrial setting because it's easy to be separated and recycled. |
