本发明提供一种利用焦炉尾气和生物沼气制取合成天然气的方法,包括如下步骤:1)将生物沼气与焦炉尾气混合,通过两股气的流量控制混合气中的氢碳比,使混合气中的氢碳比为2.9-3.1:2)对步骤1)中的混合气进行预处理和净化,再将预处理和净化后的混合气进行甲烷化反应,即可得到合成天然气(SNG)。本发明的方法可实现焦炉尾气制天然气和生物沼气制天然气的耦合,减少共有流程设置,简化
The present invention provides a method for producing synthetic natural gas from coke oven tail gas and biological biogas, which comprises the following steps: 1) mixing biological biogas with coke oven tail gas, controlling the ratio of hydrogen to carbon in the mixed gas through the flow of two gasses, The ratio of hydrogen to carbon in the mixed gas is 2.9-3.1: 2) The pretreated and purified mixed gas in step 1) is subjected to a methanation reaction to obtain a synthetic natural gas (SNG ). The method of the invention can realize the coupling of natural gas from coke oven tail gas and natural gas from biogas to reduce the common flow setting and simplify
