ABSTRACT:
A catalytic process is provided for upgrading a hydrocarbon feed stream containing pseudocumene together with a fraction of close boiling hydrocarbon compounds having a normal boiling point in a temperature range of about 320.degree. F. to about 365.degree. F. comprising contacting such hydrocarbon feed steam in the presence of hydrogen with a catalyst comprising AMS-1B crystalline borosilicate molecular sieve whereby such close boiling hydrocarbon compounds are converted to compounds having a normal boiling point below a temperature of about 300.degree. F., and fractionating the effluent product stream.
