Abstract: A NAPHTHA BOILING RANGE CHARGE STOCK CONVERTED INTO AROMATIC HYDROCARBONS AND ISOBUTANE VIA A COMBINATION PROCESS INVOLVING HYDROCRACKING, SEPARATION AND CATALYSTIC REFORMING. THE CHARGE STOCK IS INITIALLY SUBJECTED TO A NOVEL FORM OF HYDROCRACKING TO PRODUCE A PRODUCT PREDOMINANTLY COMPRISING NAPHTHENIC HYDROCARBONS AND HIGHLY BRANCHED PARAFFINS, THE MAJORITY OF THE LATTER BEING ISOBUTANE. FOLLOWING SEPARATION TO RECOVER THE ISOBUTANE AND TO PROVIDE A HEPTANE-PLUS NORMALLY LIQUID STREAM, CATALYSTIC REFORMING A UTILIZED TO DEHYDROGENATE THE NAPHTHENIC COMPOUNDS IN THE LATTER TO PRODUCE AN AROMATIC CONCENTRATE.

Abstract: A charge stock containing kerosene boiling range hydrocarbons is converted into a high-octane motor fuel which does not require the use of metal-containing additives otherwise needed for suitable anti-knock characteristics. The process involves a combination of hydrocracking and catalytic reforming, and is effected in a manner which significantly increases the quantity of normally liquid motor fuel product. The novel form of hydrocracking results in a product predominantly comprising naphthenic hydrocarbons and highly-branched paraffins, the latter being rich in isobutane. Following separation to recover the isobutane, catalytic reforming is utilized to dehydrogenate the naphthenic compounds, and dehydrocyclisize paraffinic hydrocarbons, to produce an aromatic concentrate.

Abstract: A NAPHTHA BOILING RANGE HYDROCARBON CHARGE STOCK IS CONVERTED INTO AROMATIC HYDROCARBONS AND AN ISOBUTANE CONCENTRATE VIA A COMBINATION PROCESS INVOLVING CATALYTIC REFORMING, SEPARATION AND HYDROCRACKING. THE CATALYTIC REFORMING IS EFFECTED IN TWO DISTINCT, INDIVIDUAL REFORMING REACTION ZONES, ONE OF WHICH OPERATES AT A RELATIVELY HIGH SEVERITY, AND THE SECOND OF WHICH OPERATES AT A RELATIVELY LOW SEVERITY. FOLLOWING SEPARATION OF AN AROMATIC CONCENTRATE, THE REMAINING SATURATED HYDROCARBONS ARE SUBJECTED TO A PARTICULAR HYDROCRACKING PROCESS WHICH RESULTS IN EXCEEDINGLY HIGH YIELDS OF ISOBUTANE.
