Carbon dioxide chemically bound to alcohol-amines was hydrogenated to methanol under retrieval of these industrially used CO2 capturing reagents. The energetics of the process can be seen as a partial cancellation of the exothermic heat of reaction of the hydrogenation with the endothermic one of the CO2 release from the capturing reagent. The process provides a means to significantly improve the energy efficiency of CO2 to methanol conversions.
二氧化碳与醇胺化学结合物在回收这些工业用 CO2 捕获试剂的情况下被氢化生成甲醇。该过程的能量学可以被视为部分抵消了氢化反应的放热与捕获试剂释放 CO2 的吸热之间的相互作用。该过程为显著提高 CO2 到甲醇转化的能量效率提供了一种手段。
