Abstract
The present invention relates to new crystalline zeolite SSZ-41 which comprises oxides of (1) silicon or a mixture of silicon and germanium, and (2) zinc, said zinc being present in an amount from about 2 wt % to about 5 wt % of zinc metal based on the total weight of metals in said zeolite. Zeolite SSZ-41 may also optionally contain oxides of aluminum, iron, gallium or mixtures thereof. Zeolite SSZ-41 has the X-ray diffraction lines of Table I and has an argon adsorption capacity of at least about 0.06 cc/gm at 87.degree. K. Also disclosed are methods of making and using zeolite SSZ-41.
