Development of new technology for 80% reduction of energy consumption in production of chemical materials from natural gas

本文研究了硅钼酸(SMA)催化剂用于甲烷部分氧化直接合成甲醇和甲醛，有望显着降低能耗。为了防止SMA的聚集导致催化失活，我们制备了包裹在Y型沸石孔中和空心二氧化硅颗粒中的SMA催化剂。POM中的产物产率高于沸石和二氧化硅负载的SMA催化剂，说明了包埋型SMA催化剂的有效性。然而，我们还没有达到实际使用的催化性能。

We investigated silicomolybdic acid (SMA) catalysts for the direct synthesis of methanol and formaldehyde by partial oxidation of methane (POM) which is expected to reduce the energy consumption significantly. In order to prevent the aggregation of SMA which contributes to a catalytic deactivation, we prepared the SMA catalysts encaged in pores of Zeolite Y and in hollow silica particles. The product yields in POM were higher than those over the zeolite- and silica-supported SMA catalysts, indicating the effectiveness of the encaged SMA catalysts. However, we have not achieved the catalytic performance for practical use.
