英文摘要 | the influence of pd on the catalytic performance of zr-mn-k catalyst for the selective synthesis of methanol and isobutanol from syngas was investigated. compared with zr-mn-k catalyst, the pd-promoted zr-mn-k catalyst significantly improved the reaction activity. under the reaction conditions of sv = 10000 h(-1), p = 8.0 mpa and t = 673 k, the space time yield of alcohols increased greatly from 122.8 to 232.6 g/(kg-h) when 1.5% pd (pd(no3)(2) as precursor) was addedd into the zr-mn-k catalyst, and the selectivity for isobutanol increased from 15.5% to 21.7%. however, the catalytic activity and selectivity for isobutanol greatly decreased when the pd loading exceeded 1.5%. the influence of the reaction conditions was also investigated. the reaction conditions of 15000 h(-1), higher pressure and 673 k are optimum for isobutanol synthesis from co hydrogenation. the chemisorption of h-2 and co on zr-mn-k and pd/zr-mn-k catalysts revealed that h-2 and co uptakes on pd/zr-mn-k catalyst are higher than those on zr-mn-k catalyst. the higher h-2 and co uptakes on pd/zr-mn-k catalyst would be in favor of enhancement in the rate of methanol and isobutanol synthesis. the uptakes of h-2 and co decreased with pd loading in excess of 1.5%, so that the space time yield of methanol and isobutanol decreased. |
