    Abstract

    Abstract: Ruthenium-based catalysts have been found to be the effective catalysts for the catalytic of carbon monoxide hydrogenation. In this experiment, we investigated the effects of ruthenium loading on carbon monoxide hydrogenation. A series of supported ruthenium catalysts were prepared by conventional impregnation method. The reaction was performed at an atmospheric pressure and carried out at temperature of 220 C. The reactant gas was consisted of hydrogen-carbon monoxide-argon. The flow rate of reactant gas was closed to 23 ml/min. The products were analyzed by gas chromatograph. Carbon monoxide chemisorptions, x-ray diffractometer were used to characterize the catalysts. The experiment results showed that carbon monoxide conversion was the highest for the catalyst contain 7 wt.% ruthenium loading. CH4 selectivity and olefin-to-paraffin ratio decreased with increasing ruthenium loading, on the other hand, C5+ selectivity increased with increasing ruthenium loading. 7 wt.% ruthenium loading has a metal size 9 nm, however the ruthenium metal was not detected in x-ray diffraction result.
