一种焦炉气脱碳的方法
摘要：
本发明为一种焦炉气脱碳的方法，该方法为将净化后的焦炉气，通过装填有固体混合吸附剂的变压吸附脱碳装置，CO、CO2和C2+作为强吸附组分被吸附并滞留于吸附塔中，N2、CH4和H2作为弱吸附组分从吸附塔中流出，即为脱碳气；其中，固体混合吸附剂包括以下物质：硅胶的含量为20%~80%，铜吸附剂的含量为20%~80%，氧化铝的含量为0~30%，活性炭的含量为0~30%，5A分子筛的含量为0~30%，13X分子筛的含量为0~30%，各成分百分比之和为100%。本发明提供的焦炉气脱碳方法，其仅使用变压吸附技术，不需限定焦炉气中CO+CO2的总浓度、在常温下即可操作，具有工艺流程简单，能耗低等优点。
摘要（英）：

The invention relates to a method for decarburizing coke oven gas, which is implemented in a way that: purified coke oven gas passes through a pressure swing adsorption decarburizing device filled with a solid adsorbent mixture, wherein CO, CO2 and C<2+> are adsorbed as strong adsorption components and stay in the adsorption tower, and N2, CH4 and H2 flow out of the adsorption tower as weak adsorption components which are decarburized gas. The solid adsorbent mixture comprises 20-80% of silica gel, 20-80% of copper adsorbent, 0-30% of aluminum oxide, 0-30% of activated carbon, 0-30% of 5A molecular sieve and 0-30% of 13X molecular sieve, totaling 100%. The method provided by the invention only uses pressure swing adsorption technology, does not need to limit the total concentration of CO+CO2 in the coke oven gas, can be operated at normal temperature, and has the advantages of simple technical process, low energy consumption and the like.
