| 英文摘要 | promoting effects of mg in heterogeneous mo/hbeta-al2o3 catalyst have been carefully studied for cross-metathesis of ethene and butene-2 to propene. the catalyst shows good stability with mg content in the range of 1-2 wt%. such effect may be attributed to the elimination of weak acid sites through introduction of mg which suppresses the side olefin oligomerization reaction, as evidenced from nh3-tpd and h-1 mas nmr results. addition of more mg content to 3 wt% may change the state and reducibility of mo species, as indicated from the uv-vis. uv-raman and h-2-tpr measurements. the increasing difficulty for the reduction of mo(vi) species is closely related with the poor performance of 3 wt% mg-4mo/hbeta-30% al2o3 catalyst in the metathesis reaction.
