摘要： 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.

摘要： There are herein disclosed an L-type zeolite catalyst which is obtainable by supporting a platinum component, one or more halogen components and one or more metal components selected from the group Ib of the periodic table on an L-type zeolite, the support amount of one or more metal components selected from the group Ib being in the range of 0.001 to 3% by weight based on the total weight of the catalyst in terms of the metal, a molar ratio of one or more metal components selected from the group Ib/platinum being in the range of 0.01 to 1; and a method for producing aromatic hydrocarbons or a gasoline having a high octane number which comprises the step of bringing one or more fractions selected from a C6 fraction, a C7 fraction, and a C8.sup.+ fraction into contact with this catalyst. According to the present invention, there are provided a catalyst containing an L-type zeolite as a carrier which is desirable as a catalyst for the production of aromatic hydrocarbons or a gasoline having a high octane number and which can inhibit a cracking activity and the formation of coke and can improve an aromatic selectivity and a liquid yield.

摘要： There are disclosed a new L-type zeolite and a catalyst comprising said zeolite, having a high and persistent catalytic activity for a long-term production of aromatic hydrocarbon and a process for efficiently producing aromatic hydrocarbons from nonaromatic hydrocarbon by the use of the catalyst. The L-type zeolite with both platinum components and halogen components supported thereon, has a peak intensity of 0.4 or less as determined by XANES and a small amount of dealuminization.

摘要： Crystalline aluminosilicates, a process for the production thereof and uses therefor are disclosed. The crystalline aluminosilicates are of new crystalline structure, which, as determined after calcination in the air at 550.degree. C., have a composition represented by the general formula (I):pM.sub.2/n O.Al.sub.2 O.sub.3.qSiO.sub.2(the symbols are as defined in the appended claims) and give a principal X-ray diffraction pattern as shown in Table 1. They are used as catalysts for the conversion of synthesis gas or oxygen-containing organic compounds such as alcohol, ether into hydrocarbons.
