摘要
采取连续流动法,运用微型管式反应器-色谱组合装置,考察了CH_4-H_2O(汽)-O_2体系中催化氧化制合成气的转化过程。实验表明,当混合原料组成确定后,CO含量随反应温度升高而增加;当温度一定时,降低混合原料中氧气和水蒸汽的量都会促进转化气体中CO含量的提高;在CH_4:H_2O(汽): O_2的体积比为1:0.2～0.6:0.4,反应温度800℃和接近0.1MPa的条件下,利用蒸汽和氧使天然气转化所得的合成气能满足甲醇合成用工业气体的要求。
By means of continuous flow method, the processes for syngas preparation by catalytic oxidation of CH_4-H_2O-O_2 system have been studied in a combination apparatus of microtubular reactor and chromatograph. The experimental results showed that the CO content appeared to increase with temperature when the feedstock ratio was fixed. And at the fixed temperature, the increase of CO content and decrease of CO_2 content were observed when the molar quantities of oxygen and steam in the feed gas were reduced. Under the conditions of CH_4/H_2O/O_2=1: (0. 2～0. 6) : 0. 4,800℃ and 0. 1MPa,the desired feed gas for methanol synthesis in industry was obtained.
