  • Publication number: 20240110115
    Abstract: The present invention discloses a homogenous cerium (Ce) catalyst composition comprising Ce(IV) complex alone, or Ce(IV) complex in a mixture with Ce(III) complex, that can significantly improve both LPG and soot combustion, resulting in higher flame temperatures, faster heating, reduced cooking time and reduced fuel consumption. The cerium(III) complex is cerium(III) 2-ethylhexanoate and the cerium(IV) complex is aqua(2-N-(2-hydroxyethylimino)-4-pentanoate) dinitrocerium(IV) [Ce(L1)(H2O)(NO3)2], wherein L1 is 2-N-(2-hydroxyethylimino)-4-pentanone.

  • Patent number: 11525098
    Abstract: The present disclosure describes an additive composition comprising: (a) an organometallic compound; (b) a nitrogen-containing compound; (c) an aryl peroxide; and (d) at least one solvent, wherein the organometallic compound to the nitrogen-containing compound to the aryl peroxide weight ratio is in a range of 7:0.5:0.5-9:1.5:1.5. The addition of additive composition not only synergistically improves the properties of the at least one fuel, such as, LPG for use as torch gas for cutting and welding application, but also reduces the consumption of both fuel and oxygen for cutting applications. The present disclosure is also directed towards a process for preparation of the fuel composition.
