(57) [Summary] (Modified) [Purpose] Crystalline zeolite with a new composition SSZ-32 Is prepared using the N-lower alkyl-N'-isopropyl-imidazolium cation as a template. A process for converting hydrocarbons using crystalline zeolite SSZ-32 is also provided. The composition has a molar ratio of silicon oxide to aluminum oxide of about 20: 1 to 40: 1 or less, and X in Table 1 Zeolites having line diffraction lines, (a) alkali metal oxides, N-lower alkyl-N'- Preparing an aqueous mixture containing a source of isopropyl-imidazolium cation, aluminum oxide, and silicon oxide (b) maintaining the mixture at a temperature of at least 140 ° C., A process for preparing a zeolite comprising the steps of producing crystals of the zeolite, and (c) a step of recovering the crystals, and a hydrocarbon conversion process comprising contacting a hydrocarbon feedstock with the zeolite under hydrocarbon conversion conditions. |
