摘要
CO2是最主要的温室气体,其减排和回收利用关系到可持续发展。世界CO2排放185亿～242亿t/a,只有1亿t/a得到利用。主要产品是液体CO2。我国CO2排放已超过30亿t/a,只有80万t/a得到有效利用。利用方式是干冰和液体CO2。液体CO2需求量增长速度为15%～20%,未来5年后年需量达到200万t以上。
The emission control and of CO2, the main green house gas, are related to sustainable development. World CO2 emission is 18.5-24.2 billion ton annually, in which only 0.1 billion ton can be reclaiming recovery in the form of liquefied CO2. In China the annum CO2 emission is more than 3 billion tons only 800 thousand tons can be reclaiming recovery in the form of liquefied CO2 and carbon ice. The growth rate of demand for liquefied CO2 is 15%-20% and the annual demand will be above 2 million tons in five years.
