| 摘 要： | 研究了MnOx／ZrO2催化剂中添加的碱金属助剂对以合成气合成甲醇及异丁醇反应的影响，并采用BET，XRD和NH3－TPD等表征技术，考察了碱金属助剂的添加对催化剂结构和表面性质的影响．结果表明，碱金属助剂对MnOx／ZrO2催化剂的催化性能有明显影响．在实验条件下，添加1．0％K（K2CO3作为前驱物）的催化剂，其催化性能最好，醇的选择性高达74．8％，异丁醇选择性达16．3％．添加碱金属助剂也使MnOx／ZrO2催化剂的表面性质发生了很大变化，从而影响催化剂的催化性能．

| Abstract: | The influence of alkali promoters on the catalytic performance of MnO_x/ZrO_2 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 NH_3-TPD. It was found that the addition of alkali promoters had an obvious influence on the performance of MnO_x/ZrO_2 catalyst. The selectivity for isobutanol increased in the order of Na
