介绍了2种典型的焦炉煤气制氢工艺,并对焦炉煤气直接制氢过程进行了碳排放分析,计算了该制氢过程的二氧化碳排放,指出焦炉煤气制氢相较于传统天然气制氢可减排二氧化碳88 %以上,是当下重要的低碳氢来源路径之一,同时指出发展工业副产气制氢对推动我国氢能供应体系的建设有着积极的意义。

Two kinds of typical coke oven gas to hydrogen processes are introduced,and a detailed analysis is performed on the carbon dioxide emission reduction of these processes.It is pointed out that compared with traditional natural gas to hydrogen process,coke oven gas to hydrogen process can reduce carbon dioxide emission by more than 88 %,making it one of the important sources of hydrogen with low carbon dioxide emission at present.It is also suggested that the development of hydrogen production from industrial by-product gas has positive significance in promoting the construction of China's hydrogen energy supply system.
