| 摘要: |
K-promoted Cu/Zn/Zr/La catalysts were prepared by coprecipitation and incipient wetness method and its reaction performance was evaluated in a fixed-bed reactor for the synthesis of isobutanol from CO hydrogenation.The surface properties and structure of the catalysts were altered by varying the content of potassium (0, 0.5, 1, 3wt%). Potassium showed effective promotional effects that could remarkably enhance the isobutanol selectivity in alcohol products, meanwhile methanol and isobutanol were the primary products in alcohol products. The activity of Cu/Zn/Zr/La catalysts with different content of potassium has a large difference. The isobutanol selectivity increased with increasing content of KOH and 16.06% was achieved at 673 K, 10MPa, 1/2.3 CO/H2 ratio, and 2400h-1 space time over 3%(wt)K-Cu/Zn/Zr/La. But the selectivity of methanol and isobutanol in alcohol products decreased from 99.24% to 96.02%. The appropriate amount of potassium is significant for the distribution of alcohols from CO
hydrogenation. |
