Three application modes of renewable energy under carbon neutralization target

介绍了当前CO_(2)催化氢化技术,跟踪最新CO_(2)转化研究进展,提出化工园区多能互补的CO_(2)转化循环系统。采取铁配合物Fe-PNP催化氢化CO_(2)代替传统贵金属催化剂,高效制备甲醇和甲酰胺,实现了氢、电、碳、热、水的多能互补。海岛环境下,通过海洋养殖贝类、藻类等生物固碳,构建兼顾发电、经济养殖、以种植海水稻供粮的耦合结构。利用可再生能源的余电进行黑碳提取和回收并将其施入土壤,改善土壤肥力,增加绿色植物种植面积,提出了通过植物的光合作用吸碳的构想。最后对可再生能源实现碳中和的途径和方案进行了展望。

Current CO_(2) catalytic hydrogenation technology is introduced,latest progress in CO_(2) conversion research is tracked,and a multi-energy complementary CO_(2) conversion circulation system for a chemical park is proposed.The circulation system adopts the iron complex Fe-PNP to catalyze the hydrogenation of CO_(2) instead of traditional noble metal catalyst,which produces efficiently methanol and formamide,realizing multi-energy complementation among hydrogen,electricity,carbon,heat and water.The coupling structure covering power generation,economic breeding and growing sea rice for food is established through sea-breeding shellfish,algae and other organisms to fix carbon dioxide in the island environment.Surplus electricity from renewable energy is utilized to extract and recover black carbon and apply it to the soil to improve soil fertility,and increase the planting area of green plants.The idea to absorb carbon dioxide through plant photosynthesis is proposed.The way and scheme to achieve carbon neutralization by renewable energy are prospected.
