三相搅拌釜反应器中二氧化碳加氢合成二甲醚
Synthesis of dimethyl ether from CO2+H2 in a three-phase agitated reactor
摘要
Abstract
Synthesis of dimethyl ether from carbon dioxide and hydrogen in a mechanical agi tated autoclave has been studied by using medical paraffin as inert liquid medium over hybrid catalyst composed of C302 catalyst for methanol synthesis and CM-3-1 catalyst for metha nol dehydration in the range of temperature 230～280℃、pressure 2～5MPa with the CO2:H2 rat io of feed gas at 1:3 and 1:4. The CO2 conversion and the selectivity of dimet hyl ether and methanol under various conditions were determined. The results sho wed that the proparation of two catalysts had effect on the reaction. When increasing CM-3-1, the CO2 conversion and selectivity of dimethyl ether increased.关键词
