Appl. No.:

10/424415

Inventors:

Walter R. May - Houston TX, US

International Classification:

C10L 1/18
C10L 1/24

US Classification:

44457, 44363, 44365

Abstract:

A catalyst and method for improving combustion efficiency in boilers, engines, and other equipment by adding to fossil and other fuels a fuel additive that contains an oil-soluble iron compound and an over-based magnesium compound and for which the median particle size of the additive is less than about 0. 01 micrometers.

International Classification:

C10L 10/02
C10L 1/30
C10L 1/16

Abstract:

This invention generally refers to a new generation of fuel additives which can provide catalytic action to improve the combustion process of fossil fuels and to a catalyst among others containing an iron compound combined with an over-based magnesium compound with molecular size particles inside the combustion chamber. Such fuel additive catalysts are particularly useful for fuel oil combustion, natural gas combustion, stationary gas turbines, natural gas-fired reciprocating engines, diesel engines, gasoline engines and all stationary dual-fuel engines.
