甲烷转化制甲醛有相当大的经济效益,因为甲醛常常用于制造绝缘材料和胶粘剂。本文讨论甲烷与分子氧通过MoO_3-SiO_2催化剂的一步氧化反应的动力学。在848到923K的温度范围内,空速在2500和100000h~(-1)(标准温度、压力)间变化。在0～5 %的甲烷转化范围内观测到甲醛选择性在30%和89%之间,其他主要产物为 The conversion of methane to formaldehyde is quite cost-effective because formaldehyde is often used in the manufacture of insulating materials and adhesives. This article discusses the kinetics of one-step oxidation of methane with molecular oxygen through a MoO 3 -SiO 2 catalyst. In the temperature range of 848 to 923K, the space velocity varies between 2500 and 100000h -1 (standard temperature and pressure). The formaldehyde selectivity was observed to be between 30% and 89% over the methanation range of 0-5% and the other major products were
