相转移法制备Cu-Cr甲酸甲酯加氢合成甲醇催化剂

PHASE TRANSFER PREPARATION OF CuCr METHANOL SYNTHESIS CATALYST FROM METHYL FORMATE HYDROGENATION

用戊酸铜作金属表面活性剂相转移制备了ＣｕＣｒ合成甲醇催化剂。结果发现相转移制备的产物具有与共沉淀法制备的催化剂不同的晶相结构，其粒子也要小得多，表面覆盖式ＣｕＣｒ催化剂程序升温还原后表面主要为Ｃｕ（Ⅰ）。用于由甲酸甲酯加氢制甲醇的活性显著高于共沉淀催化剂，其选择性近似１００％。

CuCr methanol synthesis catalysts were prepared with phase transfer using copper valerate as a metal surfactant The results indicated that the catalyst has smaller particles size, different crystal structure, and markedly higher hydrogenation activity for methyl formate than the one by coprecipitation Moreover, its selectivity for methanol was almost 100% Cu(Ⅰ) was produced on the surface of the CuCr catalyst by programmed temperature reduction
