催化裂化轻汽油及其醚化产品的分析

Analysis of FCC Light Gasoline and It′s Etherified Products

采用气相色谱 -质谱、气相色谱 -红外、色谱保留值法、化学法、转化率计算法等技术对催化裂化轻汽油中的组分特别是活性烯烃及其醚化产物进行了结构确定 ,用色谱峰面积校正归一法测定醚化产品中醚的含量 ;方法被用于催化裂化轻汽油的醚化催化剂评价和工艺研究。

The methods including gas chromatography-mass spectrometry,gas chromatography-infrared spectroscopy,chromatographic retention value,chemical reaction and percent conversion of etherification were used to identify the components,especially the active olefins in fluid catalytic cracked light gasoline and ethers in etherified product.The content of ethers in etherified product was determined by the peak area normalization method.The analytical approach has been used to estimate the performance of catalyst for etherifying and to study the conditions of etherification.
