    摘要: This process is for the reforming of (particularly; the aromatization of and isomerization of) alkanes to produce aromatics isonomal alkanes. Although the process and catalyst parameters can be adjusted to produce a majority of one or the other of the aromatic or isomerate products, the process is especially favorable for the production of a superior gasoline blending component having high octane blending values and containing significant amounts of both aromatics and branched paraffins. Only a small amount of cracking takes place. The process is catalytic and uses a high silica faujasite type zeolite, which contains a catalytic amount of at least one Group VIII noble metal, particularly platinum, within the pores of the zeolite.

    摘要: A synthetic crystalline zeolite is provided characterized by having a composition, in terms of mole ratios of oxides, in the range:0.1 to 0.02 R.sub.2 O:0.90 to 0.98 Na.sub.2 O:Al.sub.2 O.sub.3 :5 to 20 SiO.sub.2 :0 to 8 H.sub.2 Owherein R represents a bis-(2-hydroxyethyl) dimethylammonium group, and characterized by having atoms arranged in a structure as indicated by a specified x-ray powder diffraction pattern. The zeolite may be prepared by crystallization from an aged reaction mixture of an oxide of sodium, a bis-(2-hydroxyethyl) dimethylammonium salt, water, a source of silica, a source of alumina, and sodium aluminosilicate nucleating seeds in specified relative amounts.
