提出了一种基于碳循环的新的能量转换系统;它被称为活性碳循环能量系统（ACRES），并且已经被开发以减少二氧化碳（CO2）向大气的排放。采用固体氧化物电解槽（SOECs）对高温CO2电解再生一氧化碳（CO）进行了实验研究。实验结果表明，Pt-LSM金属陶瓷结构的电池|YSZ|在900°C时，Pt-LSM金属陶瓷的电流密度和CO生成速率最高，分别为0.52 mA·cm和0.75 μmol·min·cm。根据电解槽的电解特性，对ACRES CO2电解/炼铁联合装置的规模进行了估算。
A new energy transformation system based on carbon recycling has been proposed; it is called the active carbon recycling energy system (ACRES) and has been developed in order to reduce the emission of carbon dioxide (CO2) to the atmosphere. An experimental study based on the ACRES concept for carbon monoxide (CO) regeneration via high-temperature electrolysis of CO2 was carried out using several solid oxide electrolysis cells (SOECs). Experimental results showed that a cell with the structure Pt-LSM cermet|YSZ|Pt-LSM cermet exhibited the highest current density and CO production rates of 0.52 mA·cm and 0.75 μmol·min·cm respectively, at 900°C. On the basis of the cell’s electrolytic characteristics, the scale of a combined ACRES CO2 electrolysis/iron-making facility was estimated.
