Development of a Liquid Absorbent for the Separation of Butylene Isomers

9361123 Lyon本项目重点开发一种液体吸收剂，用于通过热吸收和变压吸收工艺分离异丁烯。吸收剂将含有过渡金属配合物，预计对异丁烯的选择性比其他C4组分高。异丁烯是汽油添加剂和轮胎的重要前体。从天然气液体和石油衍生物中分离异丁烯的低能耗方法可以降低生产成本，使该过程更具利润和竞争力。* * *

9361123 Lyon This project focuses on development of a liquid absorbent for the separation of isobutylene by thermal- and pressure-swing absorption processes. The absorbent will contain transition metal complexes which are expected to have a high selectivity for isobutylene over other C4 components. Isobutylene is an important precursor for gasoline additives and tires. Low-energy methods for the separation of isobutylene from natural gas liquids and from petroleum derivatives can reduce production costs to make the processes more profitable and competitive. ***
