摘要：The oligomerzation reactions on different catalysts were investigated and discussed. 1-Octene, 1-decene, 1-dodecene, a mixture of olefins (with a mass ratio of w(1-octene): w(1-decene):w(1-dodecene) equating to 30:40:30), and the products from paraffin cracking were oligomerized on the AlCl3/TiCl4 catalyst. The results indicated that the AlCl3 catalyst led to severe coking reaction. With an increase in carbon number of alpha-olefins, the freezing point of oligomers increased and the kinematic viscosity decreased. The oligomers formed from the mixed olefins and the paraffin cracking products showed higher kinematic viscosity. Normal paraffins contained in the cracked products could increase the freezing point of oligomers. Furthermore, the distillation range of oligomers obtained from the cracked products was close to those of oligomers originated from 1-octene and 1-decene, while the oligomers obtained from the mixed olefins and 1-dodecene had similar distillation ranges.
