【摘要】 丙烷在８００～８４０Ｋ、Ｏ２／Ｃ０３比０．４４～１．６５、停留时间６．０～１３．５ｓ的条件下进行均相氧化脱氢。在丙烷转化率为４０％时，丙烯选择性为４２．５％，产率为１７．０％。用自丙烯生产丙烯醛的Ｍｏ－Ｃｏ－Ｒｅ－Ｂｉ－Ｏ催化剂，将上述反应产物在５９０～６１５Ｋ、Ｏ２／Ｃ０３综合比０．６５～１．１３、停留时间２．４～４．２ｓ的条件下氧化，得到丙烯醛按丙烷衡算的选择性＞３３．５％，产率＞１３．５％。这些结果可与用丙烷直接催化合成丙烯醛的文献数据相比拟。更多还原

【Abstract】 Homogeneous oxidative dehydrogenation of propane was studied at temperatures of 800 840K,oxygen/prppane ratio of 0 44 1 65 and residence time of 6 0 13 5s.At 40 0% conversion of propane,the selectivity and yield of propylene obtained were 42 5% and 17 0%,respectively.Then the reaction product was passed over Mo Co Re Bi O catalyst at temperatures of 590 615K,total oxygen/propane ratios of 0 65 1 13 and residence time of 2 4 4 2s for oxidizing the product propylene into acrolein,on the basis of prppane the selectivity and yield of acrolein were >33 5% and >13 5% respectively.The results obtained are comparable to those from direct catalytic oxidation of propane into acrolein as reported in literature.更多还原
