ABSTRACT OF THE DISCLOSURE It has been discovered that the pour point and wax content of waxy hydrocarbon oils, either natural or derived from synthetic sources such as tar sands, shale oil, etc., preferably natural waxy petroleum oils, most preferably waxy lube, transformer, specialty oils and waxy fuels such as kerosene or jet fuel, can be effec- tively reduced under standard catalytic dewaxing con- ditions using an aluminosilicate catalyst with very low crystallinity (VLC), as measured by x-ray diffrac- tion. These VLC materials are derived from crystalline aluminosilicate zeolites which will not themselves reduce the pour point and wax content of waxy oils by the thermal decomposition of said zeolites following their exchange with cations which yield hydroxyl groups during the thermal decomposition step.
