摘要：采用甲醇合成 C30 2催化剂与甲醇脱水 CM- 3- 1催化剂组成的复合催化剂 ,在高压机械搅拌反应釜中进行了 CO2 加 H2 一步法合成二甲醚的研究 ,使用 CO2 ∶ H2 =1∶ 3(V∶ V)的原料气考察了温度、压力对反应转化率与各产物选择性的影响。
One step synthesis of dimethyl ether from carbon dioxide and hydrogen over hybrid catalyst composed of C302 catalyst for methanol synthesis and CM 3 1 catalyst for methanol dehydration in a mechanical agitated autoclave has been studied. Effect of reaction conditions including temperature and pressure on the conversion rate and product selectivity was observed. Because of the presence of the inert liquid phase in this process, syngas conversion can be significantly improved by co product of DME along with methanol. The coproduct strategy improves the thermodynamics and kinetic environment of the reaction system.
