Patent ID: 7390394

Claim:
The process for dewaxing a hydrocarbon feed to produce an isomerized product, the feed including straight chain and slightly branched paraffins having 10 or more carbon atoms, comprising contacting the feed under isomerization conditions in the presence of hydrogen with catalyst comprising an intermediate pore size molecular sieve which is prepared according to the following steps: (a) synthesizing 10 ring molecular sieve having one-dimensional pores, said pores having a minor axis between about 4.2 A and about 4.8 A and a major axis between about 5.0 A and about 7.0 A; (b) mixing said molecular sieve with a refractory inorganic oxide carrier precursor and an aqueous solution to form a mixture having a molecular sieve content from about 5 to about 60 wt %; (c) extruding or forming the mixture from step (b) to form an extrudate or formed particle; (d) drying the extrudate or formed particle of step (c); (e) calcining the dried extrudate or formed particle of step (d); (f) modifying the calcined extrudate or formed particle of step (e) with at least one metal selected from the group consisting of Ca, Mg, La, Ba, Na, Pr, Sr, K, and Nd to prepare a metal modified extrudate or formed particle; (g) drying of the metal modified extrudate or formed particle of step (f), (h) loading of the metal modified extrudate or formed particle of step (g) with a Group VIII metal to prepare a catalyst precursor; (i) drying the catalyst precursor of step (h); (j) calcining the dried catalyst precursor of step (i) to form a finished bound dewaxing catalyst.
