在自行设计和建立的加压动态分析装置上研究了合成甲醇催化剂上氢的吸附和反应行为。结果表明:在反应条件下催化剂上吸附的氢可分为可逆吸附氢和不可逆吸附氢;不可逆吸附氢又可分为能被CO顶替出来的和不能被CO顶替出来的两部分;能被CO顶替出来的不可逆吸附氢对CO的吸附起促进作用,不能被CO顶替出来的不可逆吸附氢是合成甲醇催化剂必不可少的“组分”或称“促进剂”;同时甲醇的生成是可逆吸附氢与一氧化碳作用的结果。
The adsorption and reaction of hydrogen on the synthesized methanol catalyst were studied on a self-designed and established pressurized dynamic analyzer. The results show that the hydrogen adsorbed on the catalyst under the reaction conditions can be divided into reversible adsorbed hydrogen and irreversibly adsorbed hydrogen; the irreversible adsorbed hydrogen can be divided into two parts which can be replaced by CO and can not be replaced by CO; Irreversible adsorption of hydrogen out on the CO adsorption role played a catalytic role can not be replaced by CO irreversibly adsorbed hydrogen is the synthesis of methanol catalyst essential “component” or “accelerator”; the same time the formation of methanol is reversible adsorption of hydrogen and The result of carbon monoxide.
