Abstract考察了催化剂中杂质Na和Fe对甲硫醚合成的催化行为的影响。Na含量越低,甲醇分解率越高。Na的质量分数在0.2%~0.4%时,甲硫醚产率最高,甲硫醇生成率最低;Na含量进一步增大时,甲醇双分子脱水生成甲醚的量增加,甲硫醇产率增高,生成甲硫醚的选择性下降。随着Fe含量的增大,甲醇分解反应加剧,硫醇产率增高,甲硫醚产率下降。
Other AbstractThe effects of Fe and Na impurities containing γ-Al2O3 catalyst on catalytic reaction of dimethyl thioether synthesis were investigated. The results indicated that the decomposition reaction of methyl alcohol was exacerbated as the Fe content increased. The mercaptan yield increased while dimethyl thioether yield decreased. The rate of decomposition of methyl alcohol increased as the Na content reduced. Both the maximum yield of dimethyl thioether and the minimum yield of methyl hydrosulfide were obtained in the Na mass fraction range of 0.2 %- 0.4%. When the Na content further increased, the yield of methy hydrosulfide increased, the selectivity of dimethyl thioether decreased.
