Catalytic hydroisomerization process

A process for dewaxing waxy hydrocarbon feedstocks to produce distillate fuels or lubricant stocks having improved pour point properties. The process comprises catalytic hydroisomerization of the feedstock over catalyst comprising a synthetic porous crystalline material characterized in its calcined...

Beschreibung
Zusammenfassung:	A process for dewaxing waxy hydrocarbon feedstocks to produce distillate fuels or lubricant stocks having improved pour point properties. The process comprises catalytic hydroisomerization of the feedstock over catalyst comprising a synthetic porous crystalline material characterized in its calcined form by an X-ray diffraction pattern including interplanar d-spacings at 12.36+/-0.4, 11.03+/-0.2, 8.83+/-0.14, 6.18+/-0.12, 6.00+/-0.10, 4.06+/-0.07, 3.91+/-0.07 and 3.42+/-0.06 Angstroms, and an Alpha Value of 10 or less.
