国内外二氧化碳市场和应用前景

CO_2 Market and Its Application Prospects at Home and Abroad

除天然CO2外,其大量为化工行业合成氨厂、石化厂、炼油厂和发酵行业酒精厂、啤酒厂生产过程的副产物。CO2及其衍生产品应用广泛、前景广阔、产生的经济效益明显。CO2可用于汽车空调制冷剂、食品快速冻结制冷剂、空调保鲜剂、干冰及研磨清洗、作固化硬化剂、萃取和超临界萃取、植物气肥农艺效应、CO2注入法提高油井产油率、合成可降解共聚物解决白色污染、和丙烷反应制取低碳烯烃、制备碳酸亚烃酯有机溶剂和有机中间体、烟丝膨胀剂、焊接保护气、饮料添加剂、灭火充加剂、生产化工产品、合成有机高分子化合物等。(孙悟)

In addition to natural existence,large mount of CO 2 is produced as byproducts in the production process in either chemical indus try such as synthesis ammonia plant,petrifaction plant and refinery etc.or fer mentation industry such as grain distillery and brewery etc.CO 2 and its derivants are widely applied in industrial fields which could bring about obvious economic benefits.The appli-cation field of CO 2 coveres the following aspects:cooling agent for automotive air conditioner ,cooling agent for food quick-freezing,antistaling agent for air conditioner ,dry ice and grinding cleaning,solidifying hardener,extraction and supercriti cal extraction,gaseous fertilizer for plants,organic solvent and organic inter medium for the preparation of alkylene carbonate,plumping agent for cut tobacco ,shielding gas during bonding,beverage additive,chemical products production ,composition of organic macromolecule compound etc.(Tran.by YUE Yang)
