能源科学技术 脱臭 Nowadays, the sweetening process of light oil including liquid-liquid Merox sweetening and fixed-bed Merox sweetening is mostly used in petroleum refining industry. 在当今炼油工业中,轻质油品的脱臭工艺主要以液—液催化氧化法和常规固定床氧化法为主。 脱硫醇 In May 2006,Karamay Refinery upgraded the FCC gasoline sweetening process to the caustic-freesweetening(Ⅱ) process by using AFS-12 catalyst and HA-20 cocatalyst, which overcame theabove limitations effectively, and achieved relatively good benefits both in economy andenvironment. 2006年5月克石化公司进行工艺改进，采用催化汽油无碱脱硫醇Ⅱ型工艺，使用AFS-12催化剂和HA-20型助剂，有效克服了这一缺陷，得到较好的经济效益和环保效益。
