FIELD: hydrocarbon conversion catalysts. SUBSTANCE: invention provides novel crystalline zeolite SSZ-41 including oxides of silicon or silicon-germanium mixture and zinc oxide, the latter being present in amounts (calculated for metal) from ca. 2 to ca. 5% based on total weight of metals in zeolite. Zeolite is characterized by x-ray diffraction corresponding to standard pattern and adsorption capacity with regard to argon at least about 0.06 cu.cm/g at 87 K. Invention also provides preparation and use of zeolite for conversion of hydrocarbons. EFFECT: increased adsorption capacity. 11 cl, 6 tbl, ex
