Abstract: A catalytic reforming process comprising the catalytic conversion of hydrocarbons to aromatics, said process comprising treating a halided zeolite catalyst (hiz-cat) containing a Group VIII metal at commercial startup conditions and then reforming hydrocarbons, wherein said catalyst is prepared by washing a bound zeolite catalyst base or a bound zeolite catalyst before halide addition. A preferred hiz-cat is a non-acidic Pt K L-zeolite catalyst prepared by a process that includes the steps of preparing a calcined silica-bound K L-zeolite catalyst base; washing said bound zeolite catalyst base with a liquid comprising water; and incorporating Pt and halogen-containing compound(s) comprising chlorine and fluorine into said washed catalyst base. Ammonium chloride and ammonium fluoride are preferred halide sources.

Abstract: A catalytic reforming process is disclosed using a catalyst containing a Group VIII metal, low amounts of bismuth, and a zeolite L. The catalyst is a non-acidic, monofunctional reforming catalyst. Preferably, the catalyst contains one or more halogens. Preferably, the feed includes C.sub.8 hydrocarbons. The addition of small amounts of bismuth increase or substantially maintain catalyst stability. Unexpectedly low dealkylation rates are achieved using the catalyst while reforming to produce aromatics, especially to produce xylenes such as paraxylene.

Abstract: There is disclosed a process for regenerating a deactivated catalyst containing a zeolite and a noble metal of group VIII of the Periodic Table supported thereon which comprises subjecting the deactivated catalyst to decoking treatment under reductive or oxidative condition and subsequently to contact treatment with a solution containing a halogen or a halogen-containing compound and thereafter calcining the deactivated catalyst. According to the above process, the catalytic activity of a deactivated catalyst is restored to the level comparable to that of a fresh catalyst by the use of an inexpensive regenerating agent and simplified steps. Thus, the regeneration process is expected to find effective use in petroleum refinery, petrochemical industry, etc.

Abstract: The aromatic hydrocarbons rich in benzene, toluene and xylene are prepared from a hydrocarbon feed having from 6 to 12 carbon atoms by feeding the hydrogen in admixture with hydrogen in a ratio ranging from 0 to less than 1 mole with respect to each mole of the hydrocarbon, into contact with a catalyst prepared by depositing at least one metal belonging to group VIII of the periodic table on a macroporous zeolite treated with a halogenated compound. The aromatic hydrocarbons rich in benzene, toluene and xylene are useful as a base for high octane number gasoline or as petrochemical raw materials.
