Abstract
The present invention relates to a hydrocarbon fuel composition comprising (i) at least 99% by weight of a base gas; and (ii) additives comprising (a) 2 to 50 ppm organometallic compound; and (b) 100 to 5000 ppm aniline or substituted aniline and 100 to 5000 ppm toluidine. The present invention discloses addition of an additive or additive mixture to base fuel preferably, liquefied petroleum gas. The addition of additive mixture not only improves the properties of the base fuel for use as torch gas for cutting and welding application, but also reduces the consumption of both fuel and oxygen for cutting applications.
