Abstract:
Dewaxed lube base stock oil which forms a wax haze on storage at a temperature above its cloud point is treated by contacting the oil and hydrogen with a zeolite catalyst such as ZSM-5 to eliminate the wax-haze formation. The method may be used to reclaim wax-contaminated lube base stock oils and other wax-contaminated hydrocarbon oils.
