铜基催化剂催化合成气一步合成甲醇和甲酸甲酯 I.温度和压力的影响(英文)

考察了在低温、低压和浆态反应条件下，由合成气一步直接合成甲醇和甲酸甲酯（ＭＦ）的反应和催化剂。结果表明，不同方法制各的Ｃｕ基催化剂具有不同的催化活性和甲酸甲酯选择性。采用络合沉淀法（ＣＰ）制备的催化剂具有较高的催化活性和ＭＦ选择性。温度和压力对催化剂的活性和ＭＦ选择性具有明显的影响。Ｃｕ－Ｃｒ催化剂的活性随温度和压力的增加而增加，其选择性随温度的升高而降低，随压力的升高而增加。

CONCURRENT SYNTHESIS OF METHANOL AND METHYL FORMATE CATALYZED BY COPPER-BASED CATALYSTS I. INFLUENCES OF TEMPERATURE AND PRESSURE

The concurrent synthesis of methanol and methyl formate(MF)from syngas at low temperature and under low pressure in a slurry reactorhas been investigated. The results shoW that the Cu-based catalysts Preparedby different methods have different activities and MF selectivities, and thecatalyst prepared by a complex Precipitation method has a higher activity ofsynthesizing methanol and MF. Temperature and Pressure have a significantinfluence on the activity and MF selectivity of the catalysts. The aCtivity ofCu-Cr catalyst increases with the augmentation of temperature and Pressure.The MF selectivity of Cu-Cr catalyst decreases with the increase oftemperature. Nevertheless, the selectivity of MF increases with the increaseof pressure.
