由CH3OH、NH3、CO直接合成DMF新反应研究

In this project, the six acid-base bifunctional catalysts ZrO2, TiO2, TiO2/MgO,ZrO2/MgO,TiO2/ZrO2/MgO and modified X-type molecular sieves were synthesized by hydrothermal synthesis and sol-gel methods, and their catalytic activities and selectivities were assessmented and evaluated. The results demonstrated that the catalytic activities and selectivities of single-component catalysts were lower than that of double-components catalysts, and the catalytic activities and selectivities of three- components catalysts were superior to that of single-components and double-components catalysts. Under the condition of 5MPa and 200,the conversion of CO can reach 28.6%, the selectivity of DMF can reach more than 80%. These results have preliminarily exhibited better industrial application prospects
