C10L - Definition
This subclass covers:
Compositions which react chemically, usually with oxygen in air, to produce heat in controllable amounts or which are dispersed in air for explosive combustion in an engine or which produce light along with heat upon combustion, i.e. liquid carbonaceous fuels, gaseous fuels, natural gas, synthetic natural gas, liquefied petroleum gas, solid fuels and fuels produced by solidifying fuels
Treatment of fuels to improve their combustion
Use of additives to fuels or fires for particular purposes, e.g. for reducing smoke development, for minimising corrosion or incrustation, for facilitating soot removal or for improving the octane number or the low temperature properties of the fuel
Fire-lighters, i.e. easily-combustible compositions or shaped products which are designed to initiate the combustion of a larger body of fuel and methods or apparatus for their manufacture
References relevant to classification in this subclass
This subclass does not cover:
Explosives or thermic compositions, e.g. fuels for rocket engines intended for reaction with an oxidant other than air | C06B |
Fuels for generating pressure gas, e.g. for airbags or for propulsion of rockets | C06D 5/00 |
Cracking hydrocarbon oils, production of liquid hydrocarbon mixtures, e.g. by destructive hydrogenation, oligomerisation or polymerisation, recovery of hydrocarbon oils from oil-shale, oil-sand, or gases, refining mixtures mainly consisting of hydrocarbons and to reforming of naphta | C10G |
Mineral waxes | C10G |
Production of producer gas, water-gas, synthesis gas from solid carbonaceous materials, or mixtures containing these gases or carburetting air or other gases | C10J |
Purifying or modifying the chemical compositions of combustible gases containing carbon monoxide | C10K |
Fuels for generating pressure gas, e.g. for rockets | C06D 5/00 |
Attention is drawn to the following places, which may be of interest for search:

Hydrocarbons per se | C07C |
Cracking or pyrolysis of hydrocarbon gases to individual hydrocarbons or mixtures thereof of definite or specified constitution | C07C |
Destructive distillation of carbonaceous materials for producing of gas, coke, tar, or similar materials | C10B |
Lubricating compositions | C10M |
Candles | C11C |
Arrangements or devices for supplying additives to fuels in combustion engines, e.g. | F02, F02M 25/00 |
Vessels for containing or storing compressed, liquefied or solidified gases | F17C |
Liquefying gases or gaseous mixtures by pressure and cold treatment | F25J |
Nuclear reactor fuels | G21C 3/00 |
In this subclass, the following terms or expressions are used with the meaning indicated:
