化学合成获取天然气资源的路径分析

Pathway analysis on chemical synthesis of natural gas

甲烷化是一种把CO、CO2和H2在催化剂作用下化学合成制取天然气的过程。对国内处于产能过剩、盈利边缘的合成氨和合成甲醇装置进行改造制合成天然气在技术上是可行的,可获得中、小型规模天然气资源。甲烷化技术使天然气获取来源更广泛,包括稠油、渣油、生物质、油砂、煤的气化气,也可是焦炉尾气、黄磷尾气、兰炭尾气、电石尾气等工业排放气。

Methanation technology is a process to chemically synthesize natural gas through catalysis of CO, CO2 and H2. Modification of ammonia and methanol synthetic units which is overcapacity and at the edge of profit is technically feasible to achieve natural gas at a small or moderate scale. Methanation can chemically synthesize natural gas from heavy oil, residual oil, biomass, oil sand, coal gas or industrial vent gas including coke oven flue gas, yellow phosphorus tail gas, blue carbon tail gas, calcium carbide tail gas, and so on.
