Abstract: Using hydrophobic nanosilicon dioxide, deionized water and basic compounds as the raw material, dry water and dry alkali catalysts such as white granulated sugar were prepared. The effect of mass ratio on form of dry water and alkaline dry alkali was investigated. The effect of the different dry base catalysts, content of active constituents, gas flow and service life of the catalyst on the COS hydrolysis transforming rate were investigated. The results showed that under the condition of room temperature, gas flow of 10 mL/min, dry calcium oxide(CaO(1 g)+deionized water(79 g)+hydrophobic nanosilicon dioxide(20 g) were the optimum catalyst active component ) of 2 g, COS hydrolysis transforming rate reached 90%, and the service life of the catalyst was 340 min.

摘要: 以疏水性纳米二氧化硅、去离子水和碱性物质为原料,考察其质量配比对干水和碱性干碱形态的影响,并制备出像白砂糖状的干水和干碱催化剂。考察不同的碱性干碱、活性组分质量、气体流量和催化剂使用寿命对COS催化水解的影响。结果发现,在室温、气体流量10mL/min、催化剂质量2g条件下,碱性干氧化钙(制备配比为m (氧化钙)/m (去离子水)/m (纳米二氧化硅)=1∶79∶20)催化COS水解转化率达90%时,该催化剂的使用寿命为340min。
