Novel Catalysts for Low-temperature Co-methanation of CO and CO2 in Coke Oven Gas
, 2014 焦炉气是在炼焦过程中产生的副产品，主要成分是氢气和甲烷，还有一氧化碳、二氧化碳、烯烃等。每年中国焦炉气的产量约1200亿Nm3，其利用率约为55%，焦炉气通过甲烷化反应，将焦炉气中CO、CO2转化为甲烷，再通过变压吸附生产天然气具有较好经济价值和社会意义。甲烷化是强放热反应，反应器局部温升可以造成碳烃裂解而结碳，还可能容易使甲烷化催化剂烧结而失活。针对焦炉气甲烷化的工艺特点，本研究主要开发适于焦炉气中低温甲烷化催化剂。 本研究对于富氢焦炉气的甲烷化过程进行系统的分析和研究 ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
