Abstract

The oligomerization of 1-pentene is an efficient process for producing environmentally friendly high-quality fuel components. The catalytic properties of FAU, OFF, MOR, BEA, MTW, and MFI zeolites in the H form are studied in the synthesis of pentene oligomers in an autoclave at 110–200°C. It is established that the high activity of H-Y and H-Beta(18) zeolites in the reaction of oligomerization, where the yield of oligomers reaches 97–100%, is determined by their wide-pore structure and high concentration of acid sites. The oligomers prepared on these catalysts are 30–73% dimers, 25–50% trimers, and 2–14% oligomers, with number n > 3 of monomer units. Narrow-pore zeolites (H-ZSM-5) or zeolites with one- and two-dimensional channel systems (H-OFF, H-MOR, and H-ZSM-12) are less active in the oligomerization of 1-pentene, with decenes as the main products of the reaction.

1-戊烯在沸石催化剂上的低聚

摘要

1-戊烯的低聚是生产环境友好的高质量燃料组分的有效方法。H型FAU，OFF，MOR，BEA，MTW和MFI沸石的催化性能已在110-200°C的高压釜中合成戊烯低聚物时进行了研究。已经确定，HY和H-Beta（18）沸石在低聚反应中的高活性（低聚物的收率达到97-100％）取决于它们的宽孔结构和高酸性位点。用这些催化剂制备的低聚物为30–73％二聚体，25–50％三聚体和2–14％低聚物，编号n> 3个单体单元。窄孔沸石（H-ZSM-5）或具有一维和二维通道系统的沸石（H-OFF，H-MOR和H-ZSM-12）在1-戊烯的低聚反应中活性较低下降是反应的主要产物。
