【摘要】 系统地研究了γ－Al2O3催化剂中杂质Fe和Na,对二甲基硫醚合成的催化行为的影响，研究结果表明，随着Fe含量的增大，甲醇分解反应加剧，硫醇产率增高，二甲基硫醚产率下降；Na含量降低，甲醇分解率越高，Na含量在0.2％～0.4％时，二甲基硫醚产率最高．甲硫醇生成率最低．更多还原

【Abstract】 The effects of Fe and Na in γ-A12O2 on catalytic reaction of dimethly thioether synthesis were systematically studied.The results indicated that the decomposition reaction of methly alcoholwas exacerbated and mercaptan yield increased while dimethyl thioether yield decreased as the Fe content increased.The rate of decomposition of methly alcohol increased when the Na content was reduced.Themaximum dimethyl thioether productivity and the rninmum methyl hydrosulfide productivity can be obtained in the Na content range of 0.2～0.4 percent.更多还原
