Fuel additive composition and related methods and compositions
First Claim
1. A fuel additive composition comprising:
- (a) hydrotreated heavy paraffinic distillates present in amount ranging from 20 wt. % to 50 wt. % based on the fuel additive composition;
(b) solvent-dewaxed heavy paraffinic distillates present in amount ranging from 25 wt. % to 50 wt. % based on the fuel additive composition; and
(c) petroleum distillates comprising hydrocarbons having from 5 to 16 carbon atoms and present in an amount ranging from 20 wt. % to 50 wt. % based on the fuel additive composition.

Abstract
The disclosure relates to fuel additive compositions including heavy paraffinic distillates and lighter petroleum distillates, in particular with the heavy paraffinic distillates including a mixture of hydrotreated and/or saturated components and solvent-dewaxed and/or branched components. The disclosure further relates to fuel compositions including the fuel additive composition and a liquid or solid combustible fuel. Related methods include methods of making the fuel compositions and methods of burning the fuel compositions. The resulting fuel compositions have several improved combustion properties such as improved combustion efficiency, improved combustion energy/calorie content, reduced sulfur generation, and reduced ash generation.
