CO_2减排技术
technology for reduction of CO_2 emission

  COZJ一onPo一J一shuCO:减排技术(teehnology for reduetion ofCOZ emission)用化学、物理、生态等方法从烟气或煤气中分离、回收利用或处理CO:,以减少或分离化石燃料燃烧生成的C02或分离煤气或天然气中C02的技术。也称碳整合技术(earbon sequestration)。 此项技术当前尚处于可行性研究或试验阶段,主要有:①分离回收技术:以氛系为吸收液的化学吸收法,用类似于沸石等固体吸附剂的物理吸收法和利用高分子膜对不同气体的不同渗透速度将C02从烟气中分离出来的膜分离法等。②利用技术:液化COZ已广泛地用于焊接、冷却、生产碳酸盐和尿素及饮料等领域,但大t地利用C02的技术,如C02与HZ在高温高压和催化剂条件下合成甲醇、甲烷,与乙醇、环氧化物及不饱和碳化氢合成各种含氧有机化合物等则正在研究之中。③储存技术:将分离出来的C02液化后存放在地下蓄水层或废弃的油井、气井中,或储存于深海等。④加强自然界的补偿:大气与海洋、森林生物圈之间的COZ交换,与人为的CO:排放相比是非常巨大的,只要稍徽增加全球碳循环中CO:的吸收量,就会对大气中温室气体浓度的降低起显著作用,为此要禁止砍伐森林,扩大森林种植和复种面积,增加CO:在现有森林中的存储t。 庞大的回收、处理设备需要大量的建设资金和运行费用。据估算,对于一座500 MW的火电厂,如采用化学吸收法从烟气中吸收CO:,液化后储存在soom深的海底,燃用天然气时发电成本要增加50写~7。%,嫩用煤炭时发电成本要增加130%~190%。目前实施这些减排技术,困难很大,尚需进一步研究。
