Method of treating a petroleum fraction using molecular sieve aluminosilicate selective adsorbents

Claim 1

A METHOD OF REFORMING A PETROLEUM FRACTION CONTAINING STRAIGHT CHAIN HYDROCARBONS AND NON-STRAIGHT CHAIN HYDROCARBONS WHICH COMPRISES CONTACTING SAID FRACTION WITH A SOLID PARTICLE MOLECULAR SIEVE ALUMINO-SILICATE SELECTIVE ADSORBENT MADE UP OF POROUS CRYSTALS WHEREIN THE PORES OF THE CRYSTALS ARE OF UNIFORM SIZE AND HAVE A PORE SIZE OF ABOUT 5.0 ANGSTROM UNITS, A PORE SIZE SUFFICIENT TO ADMIT STRAIGHT CHAIN HYDROCARBONS TO THE SUBSTANTIAL EXCLUSION OF NON-STRAIGHT CHAIN HYDROCARBONS, AND WHICH SELECTIVELY ADSORBS STRAIGHT CHAIN HYDROCARBONS FROM BONS TO BE SUBSTANTIAL EXCLUSION OF NON-STRAIGHT CHAIN HYDROCARBONS TO ADSORB STRAIGHT CHAIN HYDROCARBONS FROM SAID FRACTION, SUBJECTING THE RESULTING PETROLEUM FRACTION HAVING A REDUCED PROPORTION OF STRAIGHT CHAIN HYDROCARBONS TO CATALYTIC REFORMING, INCLUDING DEHYDROGENATION, TO PRODUCE A REFORMED PETROLEUM FRACTION OF IMPROVED QUALITY AND A RESULTING NET PRODUCTION OF HYDROGEN, RECOVERING AT LEAST A PORTION OF THE RESULTING PRODUCED HYDROGEN AND EMPLOYING THE RECOVERED HYDROGEN AS A STRIPPING MEDIUM TO DESORB THE ADSORBED STRAIGHT CHAIN HYDROCARBONS FROM SAID ADSORBENT.
