NOVELTY - Hydrocarbon feed comprising 10C or more paraffins is contacted under isomerization conditions in presence of hydrogen with catalyst having intermediate pore size molecular sieve, to obtain isomerized product. The catalyst is prepared by mixing zeolite with inorganic oxide carrier precursor and aqueous solution. The mixture is extruded/formed, dried and calcined. The extrudate/formed particle is loaded with hydrogenation component to prepare catalyst precursor. Precursor is dried and calcined to form a finished bound dewaxing catalyst.    USE - For dewaxing hydrocarbon feed to obtain maximized yield of isomerized product and a minimized yield of light ends.    ADVANTAGE - The catalyst has less defined crystallinity, altered argon adsorption ratio, increased surface area and reduced cracking activity over other intermediate pore size molecular sieves used for isomerization. The catalyst when used in isomerization results in higher lube product yield and lower gas production.    DETAILED DESCRIPTION - A hydrocarbon feed including straight chain and slightly branched paraffins having 10 or more carbon atoms, is contacted under isomerization conditions in the presence of hydrogen with catalyst comprising an intermediate pore size molecular sieve, to obtain a maximized yield of isomerized product and a minimized yield of light ends. The catalyst is prepared by following steps. A zeolite having a mole ratio of silicon oxide to aluminum oxide of 20:1-40:1 with crystallites having small broad lathe-like components of 200-400 Angstrom, is mixed with a refractory inorganic oxide carrier precursor and an aqueous solution to form a mixture having a molecular sieve content of 10-90 wt.%. The resulting mixture is extruded or formed, to form an extrudate or formed particle. The extrudate or formed particle is dried and calcined. The extrudate or formed particle is loaded with a hydrogenation component to prepare a catalyst precursor. The catalyst precursor is dried, and the dried catalyst precursor is calcined to form a finished bound dewaxing catalyst.    The zeolite has X-ray diffraction lines of 23 peaks such as peaks having 2theta of 8.03, d-spacing of 11 Angstrom and relative intensity of 30%; peaks having 2theta of 22.74, d-spacing of 3.9 Angstrom and relative intensity of 63%; and peaks having 2theta of 36.29, d-spacing of 2.47 Angstrom and relative intensity of 16%. The zeolite is synthesized by employing the following steps. N-lower alkyl-N-methyl-N'-isopropyl-imidazolium cation which is ion-exchanged to the hydroxide form (in parts) (5), alkali metal hydroxide (20), silica (100) and alumina (3.5), and alkyl amine (20), are combined to form mixture. The mixture is stirred in an autoclave, under autogenous pressure, in a range of 500-1500 rpm for 0.5-5 hours, and maintained at an elevated temperature for 40-120 hours to form the crystals of the zeolite. The crystals of the zeolite are collected by filtration or by centrifugation and subjected to calcination and ion exchange.
