This patent describes a process for cracking a feedstock comprising hydrocarbon compounds to lower molecular weight hydrocarbon compounds, which process comprises contacting the feedstock at conversion conditions with a catalyst composition comprising a silicous zeolite prepared by the method comprising providing a boron-containing zeolie Beta with initial boron and aluminum contents each greater than the numeral 0, treating the zeolite with silicon tetrachloride at a temperature for a time sufficient to replace boron with silicon, and recovering the siliceous zeolite having reduced boron content but substantially preserved aluminum constant.
