Paper Title:
Modification of L Zeolite and Hydroisomerization of N-Dodecane over Pt/L Catalysts and Pt/SAPO-11 Catalyst
  Abstract

We have presented the synthesis and modification of L zeolite, and have further investigated the hydroisomerization of n-dodecane over the Pt/HL catalyst in a fixed bed reactor by changing reaction parameters such as temperature and pressure, respectively. The results showed that the combined use of ion-exchange, critric acid treatment and hydrothermal treatment could improve the Si/Al ratio of L zeolite dramatically while the high crystallinity was held. The Pt/HL catalyst showed higher stability, good regeneration property, catalytic activity and selectivity to the branched isomers under relatively low reaction pressures compared to the Pt/SAPO-11 catalyst.
