ABSTRACT:
This invention concerns a time-effective method of manufacture for a sodium ferrierite precursor of a hydrogen ferrierite catalytic composition of matter by crystallizing an aqueous mixture of sodium hydroxide, an aluminum compound, a silicon compound and a nitrogen-containing compound, which mixture possesses 1.60 to 3.40 moles of sodium oxide and 0.70 to 1.60 moles of aluminum oxide per 25 moles of silicon oxide. The ultimate use of the resultant catalyst is for removing wax from a lubricating oil (preferably a light lubricating oil) with or without the metals of Group VIII and/or Group VIB used in association with the catalyst.
