Abstract
A hydrocarbon fuel oil composition comprising a blend of untreated low pour-point distillate oil and a higher pour-point catalytically hydrodewaxed distillate oil. The blend has an unexpectedly low pour point and cloud point. Dewaxing is effected with a ZSM-5 type catalyst.
Claims5
A blended hydrocarbon fuel oil comprising an untreated distillate oil having a pour point of about -21.degree. to 30.degree. F combined with a hydrodewaxed oil produced by hydrodewaxing a high pour hydrocarbon distillate having a pour point greater than about 30.degree. F with a ZSM-5 type catalyst under a hydrogen pressure of about 100 to 1500 p.s.i.g., at a space velocity of about 0.5 to 10 L.H.S.V., and at a temperature of about 500.degree. F to about 850.degree. F, said hydrodewaxed oil having a pour point higher than said untreated distillate oil.
