在合成乙醇的Rh/SiO_2健化剂中,开发了添加几种高效能成分的助催化剂。本文将报道Rh-Ti-Fe-Ir/SiO_2作为选择合成乙醇的良好催化剂。这类催化剂系通过一种常用的共浸渍法制备的。该法采用含有若干数量的RhCl_3·3H_2O和添加盐类的乙醇溶液,浸渍16～32目的SiO_2。TiCl_4、FeCl_3·6H_2O和IrCl_4·H_2O用作添加剂前体。浸渍后催化剂通过温度达120℃的旋转式汽化器,充分进行干燥。然后用氢气流在温度从20℃上升至
In the synthesis of ethanol Rh / SiO 2 Jianzhu agent, the development of adding several high-performance components of the cocatalyst. This article reports that Rh-Ti-Fe-Ir / SiO 2 is a good catalyst for the selective synthesis of ethanol. Such catalysts are prepared by a common co-impregnation method. The method uses a certain amount of the amount of RhCl_3 · 3H_2O and added salt solution of ethanol, impregnated with 16 ~ 32 mesh SiO2. TiCl 4, FeCl 3 · 6H 2 O and IrCl 4 · H 2 O were used as additive precursors. The impregnated catalyst was passed through a rotary vaporizer with a temperature of 120 ° C and dried well. The flow of hydrogen then rose from 20 ° C to a temperature of 20 ° C
