摘　　要：介绍了华烁科技股份有限公司开发的食品级CO2气体常温精脱硫与脱烃新技术的开发和应用进展.常温精脱硫技术可将CO2气体中总硫（H2S、COS、SO2、CS2、硫醇等）脱除至≤0.1×10^-6 （Ⅴ/Ⅴ）；脱烃新技术可将CO2气体中总烃脱除至＜50×10-6（V/Ⅴ）,苯＜0.02×10-6（Ⅴ/Ⅴ）.应用表明,该技术可保证食品级CO2三项关键指标达到国际质量标准和国家标准,脱烃催化剂累计使用寿命可达3～5年.This text introduced progress of development and application of ambient temperature fine desulfuration and hy- drocarbon-removal new technology in food grade COz developed by Haiso Technology Co. , Ltd.. Ambient temperature fine desulfuration technology could remove total sulfur of CO2 gas （H2S, COS, SO2, CS2, thiol and so on） to less than 0.1 ×10^-6 （V/V）. Hydrocarbon-removal new technology could remove total hydrocarbons of CO2 gas to less than 50 ×10^-6（V/ V）, benzene to less than 0.02 ×10^-6 （V/V）. The application result showed that this technology could ensure three key in- dex of food grade CO2 reach international quality standards and national standards, the cumulative life of the hydrocarbon- removal catalysts could reach three to five years.
