Abstract
The concentration of hydrogen sulfide in a hydrocarbon can be mitigated by intruding therein a zinc carboxylate oxo complex composition prepared by reacting particulate zinc oxide with a mixture of two or more carboxylic acids wherein the zinc carboxylate oxo complex composition is soluble in hydrocarbons. Useful acids useful include acetic acid, oleic acid, isobutyric acid, lineoleic acid, cekanoic acid, and neodecanoic acid.
Claims13
A method for reducing the concentration of hydrogen sulfide in a hydrocarbon comprising:
- introducing a zinc carboxylate oxo complex composition into the hydrocarbon;
- wherein the zinc carboxylate oxo complex is the reaction product from reacting particulate zinc oxide with a mixture of two or more carboxylic acids;
- wherein the zinc carboxylate oxo complex composition is soluble in hydrocarbons;
- and wherein none of the acids is octanoic acid or an octanoic isomer.
A method for reducing the concentration of hydrogen sulfide in a hydrocarbon comprising:
- introducing a zinc carboxylate oxo complex composition into the hydrocarbon;
- wherein the zinc carboxylate oxo complex is the reaction product from:
- mixing two or more carboxylic acids together to form a carboxylic acid mixture;
- wherein none of the carboxylic acids is octanoic acid or an octanoic isomer;
- and wherein the two or more carboxylic acids are selected from the group consisting of acetic acid, isobutyric acid, and neodecanoic acid;
- and
- reacting particulate zinc oxide with the carboxylic acid mixture to form the zinc carboxylate oxo complex;
- wherein the zinc carboxylate oxo complex composition is soluble in hydrocarbons.
