甲烷催化部分氧化制甲醇

Catalytlc partial oxidation of methane to methanol

在约250℃温度和0.4MPa压力下,采用Cr8+—Zr4+—SO42-/硅胶催化剂,对甲烷催化部分氧化制甲醇进行了研究。并讨论了生成产物的反应路线。产物中含有甲醇、甲醛、CO2和CO等含氧化合物。甲烷转化率约为5%,甲醇选择性超过70%,甲醇收率超过3%。

The catalytic partial oxidation of methane to methaol was studied in the presence of Cr^(3+) - Zr^(4+) - SO_4^(2-)/silica gel catalyst at temperature about 250℃ and under 0.4MPa. The pathway of reaction for the production of final products was discussed. The products consisted of oxygen-containig compounds involving methanol, formaldehyde and carbon oxides with a methane conversion of about 5%, a selectivity to methanol exceeding 70% and a methanol yield over 3%.
