摘要
综述了目前国内外燃煤电厂CO_(2)捕集、利用与封存(CCUS)技术的分类、原理、优缺点及工业应用现状.结合我国能源消费结构的现状与未来趋势,根据技术成熟度、成本、碳减排潜力等,为我国燃煤电厂CCUS提出技术路线选择.我国现有和短期(2030年前)燃煤电厂碳捕集应以燃烧后化学吸收技术为主,CO_(2)利用以强化采油(EOR)和矿化技术为主,化工合成与微藻等多技术并存,其中EOR依赖特定区域.2030—2050年间,燃煤电厂碳捕集以燃烧前整体煤气化联合循环发电系统(IGCC)-化学吸收技术为主,固体吸附与膜分离为辅,CO_(2)利用以合成燃料、强化采气技术为主,其中合成燃料技术对可再生能源和氢能有较强依赖性.2050年后,燃煤电厂以富氧燃烧和化学链燃烧为主要碳捕集技术,强化采气和咸水层封存等技术为主要CO_(2)利用与封存技术,实现我国碳中和目标.
The classification,principle,advantages and disadvantages and industrial application status of CO_(2) capture,utilization and storage(CCUS)technology in coal-fired power plants at home and abroad were summarized.Combined with the current situation and future trend of China's energy consumption structure,and according to the technical maturity,cost and carbon emission reduction potential,the technical route selection for China's coal-fired power plant CCUS was put forward.Carbon capture in China's existing and short-term(before 2030)coal-fired power plants should focus on post combustion chemical absorption technology,CO_(2) utilization should focus on enhanced oil recovery(EOR)and mineralization technology,chemical synthesis and microalgae coexist,in which EOR depends on specific areas.From 2030 to 2050,the carbon capture of coal-fired power plants is mainly based on integrated gasification combined cycle(IGCC)chemical absorption technology before combustion,supplemented by solid adsorption and membrane separation.The CO_(2) utilization is mainly based on synthetic fuel and enhanced gas production technology.Among them,synthetic fuel technology is highly dependent on renewable energy and hydrogen energy.After 2050,coal-fired power plants will take oxygen enriched combustion and chemical chain combustion as the main carbon capture technology,and strengthen gas production and salt water layer storage as the main CO_(2) utilization and storage technology,so as to achieve the goal of carbon neutralization in China.
