Dewaxing by isomerization
Patent
·
OSTI ID:6480907
This patent describes a process for dewaxing a hydrocarbon feedstock containing paraffins which comprises contacting the feedstock under isomerization conditions with a catalyst comprising a hydrogenation component and siliceous zeolite having been prepared by a method comprising providing a boron-containing zeolite Beta with initial boron and aluminum contents each greater than the numeral O, 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.
