ABSTRACT:
Relatively heavy or relatively light lube chargestocks are dewaxed in two parallel, separate reactors. The reactor used for dewaxing the relatively light chargestocks contains a crystalline aluminosilicate zeolite exemplified natural or synthetic ferrierite, ZSM-22, ZSM-23 and ZSM-35 zeolites and/or mixtures thereof. The reactor used for dewaxing the relatively heavy chargestocks contains a crystalline aluminosilicate zeolite exemplified by ZSM-5, ZSM-11 zeolites, ZSM-5/ZSM-11 intermediates and/or mixtures thereof.
