In many reactions restricted by water, selective removal of water from the reaction system is critical and usually requires a membrane reactor. We found that a simple physical mixture of hydrophobic poly(divinylbenzene) with cobalt-manganese carbide could modulate a local environment of catalysts for rapidly shipping water product in syngas conversion. We were able to shift the water-sorption equilibrium on the catalyst surface, leading to a greater proportion of free surface that in turn raised the rate of syngas conversion by nearly a factor of 2. The carbon monoxide conversion reached 63.5%, and 71.4% of the hydrocarbon products were light olefins at 250°C, outperforming poly(divinylbenzene)-free catalyst under equivalent reaction conditions. The physically mixed CoMn carbide/poly(divinylbenzene) catalyst was durable in the continuous test for 120 hours.

催化剂和疏水性聚合物的物理混合通过脱水促进 CO 加氢

在许多受水限制的反应中，从反应系统中选择性去除水是至关重要的，通常需要膜反应器。我们发现疏水性聚（二乙烯基苯）与钴锰碳化物的简单物理混合物可以调节催化剂的局部环境，从而在合成气转化中快速运输水产品。我们能够改变催化剂表面的吸水平衡，导致更大比例的自由表面，从而将合成气转化率提高近 2 倍。一氧化碳转化率达到 63.5% 和 71.4%在 250°C 的烃类产品中，轻质烯烃的性能优于无聚（二乙烯基苯）催化剂。
