Abstract
The specification discloses conversion of hydrocarbons using, as catalyst, a crystalline zeolite designated ZSM-12. The zeolite has the following composition: 1,0 .+-. 0.4 M.sub.2 O . W.sub.2 O . 20-200 YO.sub.2 . ZH.sub.2 O where M is at least one cation and n is the valence thereof, W is aluminum or gallium, Y is silicon or germanium, and Z is a value ranging from 0 to 60. In a preferred synthesized form, M is a mixture of alkali metal cations, especially sodium, and tetraalkylammonium cations. These zeolites are characterized by a specified x-ray powder diffraction pattern. Catalytically-active forms of said zeolites are used in a wide variety of hydrocarbon conversion reactions.
Claims7
A process for conversion of a hydrocarbon charge which comprises contacting said charge under conversion conditions with a catalyst comprising a zeolite the X-ray powder diffraction pattern of which manifests the interplanar spacings set forth in Table 1 of the specification when the zeolite is in the sodium-tetraethylammonium cationic form, said zeolite having, in terms of mole ratios of oxides, the formula:
- 1 .+-. 0.4 M.sub.2/n O:
- W.sub.2 O.sub.3 :
- 20-200YO.sub.2 :
- zH.sub.2 O
- wherein M is at least one cation having a valance n, z is between 0 and 60, W is aluminum or gallium and Y is silicon or germanium.
