ABSTRACT:
A process is provided for converting feedstock comprising hydrocarbon compounds to product comprising hydrocarbon compounds of lower molecular weight than feedstock hydrocarbon compounds over a catalyst comprising a siliceous zeolite prepared by the method comprising providing zeolite Beta containing boron and aluminum, 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. In particular embodiments, the conversion is selective cracking for waxes and the process is useful for reducing the pour point of fuel oils and lubricants.
