Enhanced methanation stability of nano-sized MoS

Zhenhua LI, Jia HE, Haiyang WANG, Baowei WANG, Xinbin MA

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 1,   Pages 33-39 doi: 10.1007/s11705-014-1446-6

Abstract: A series of unsupported MoS catalysts with or without Al O modification was prepared using a modified thermal decomposition approach. The catalysts were tested for the methanation of carbon monoxide and the optimum one has 25.6 wt-% Al O content. The catalysts were characterized by nitrogen adsorption measurement, X-ray diffraction and transmission electron microscopy. The results show that adding appropriate amount of Al O increases the dispersion of MoS , and the increased interaction force between MoS and Al O can inhibit the sintering of active MoS to some extent.
