英文摘要the influence of alkali promoters on the catalytic performance of mnox/zro2 for the selective synthesis of methanol and isobutanol from syngas was studied. the crystal structure, bet specific surface area and acidic properties of catalyst samples were measured by xrd, n-2 adsorption and nh3-tpd. it was found that the addition of alkali promoters had an obvious influence on the performance of mnox/zro2 catalyst. the selectivity for isobutanol increased in the order of na < li < rb < cs < k, which indicated that the moderately basic additives were desired for the formation of isobutanol on mnox/zro2 catalyst. the selectivity for isobutanol was strongly dependent on the anions of the potassium salts, increasing in the order of oh- < c2o42- < no3- < co32-, which revealed that a moderate alkali promotion was required. the catalyst of 1% k/mnox/zro2 (k2co3 as precursor) showed higher activity and selectivity for isobutanol under the conditions of 10 000 h(-1), 8.0 mpa and 673 k. the selectivity for alcohols and isobutanol was 74.8% and 16.3%, respectively. the results of characterization suggested that the acidic or basic property on the catalyst surface may play an important role in the formation of isobutanol.
