从CO和H_2合成甲醇已在无载体的单晶钯(110)上,于压力72.3～244k Pa、温度493～553K和H_2/CO之比为3.9条件下,在一个组合的高压反应器-超高真空表面分析室中进行了研究。在244kPa压力下,该反应显示出线性Arrhenius特性,具有77.04kJ/mol活化能和8×10~4S~(-1)频率因子。这些值与报道的Pd/SiO_2载体型催化 The synthesis of methanol from CO and H 2 has been carried out in a combined high-pressure reactor, super-ultra-high pressure reactor, on a carrier-free monocrystalline palladium (110) at a pressure of 72.3 to 244 k Pa, a temperature of 493 to 553 K and a H 2 / CO ratio of 3.9 High vacuum surface analysis chamber was studied. The reaction showed a linear Arrhenius behavior at a pressure of 244 kPa with an activation energy of 77.04 kJ / mol and a frequency factor of 8 × 10 -4 S -1. These values ​​are in agreement with the reported Pd / SiO 2 carrier-type catalysis
