摘要
介绍了碳八芳烃异构体工业分离技术的现状、对二甲苯分离技术的新发展。评述了择形催化生产对二甲苯的技术、利用结晶处理高浓度对二甲苯原料、变压吸附低成本浓缩对二甲苯技术、分子筛膜分离对二甲苯等。
Production technologies of C8 aromatics isomers are introduced. The progress of p-xylene separation technologies is discussed. Shape selective catalytic technology could produce high concentration p-xylene. Crystallization becomes more important in treating high concentration p-xylene feed; Pressure swing adsorption is emerging as a low cost concentration technology. Separating xylene isomers with zeolite membrane has got remarkable progress.
