Abstract

Abstract

MO_x/USY catalysts (M=Co,Mo,Co-Mo) were prepared by incipient wetness impregnation method. Catalytic pyrolysis of Huang Tu Miao (HTM) coal was investigated and the pyrolysis products were examined by TG-FTIR technique. TG results indicate that MO_x/USY catalysts are effective in lowering degasifiction temperature (14, 23 and 9℃ respectively) in HTM coal pyrolysis. Kinetic calculations show that MO_x/USY catalysts are effective in lowing activation energy of pyrolysis. FT-IR analyses show that the MO_x/USY catalysts are effective in manipulating coal pyrolysis products. CoO_x/USY catalyst promote the generation of CH₄, CO and aromatic hydrocarbons and aliphatic hydrocarbons in HTM coal pyrolysis. MoO_x/USY catalyst show little effect in manipulating pyrolysis products. CoO_x-MoO_x/USY catalyst is a promising catalyst in giving high yield of volatile products, however the pyrolysis temperature moved to high temperature region. These results indicate that different metal oxides incorporated zeolite USY have different impact on manipulating pyrolysis products.
