Dewaxing by isomerization |
摘要 |
A process is provided for dewaxing hydrocarbon feedstock by isomerizing the waxy components of the feedstock over catalyst comprising a siliceous zeolite having been prepared by the method comprising providing a boron-containing zeolite Beta, treating the zeolite with silicon tetrachloride at a temperature and for a time sufficient to replace boron with silicon, and recovering the siliceous zeolite having reduced boron content but substantially preserved initial aluminum content.
