Abstract

Provided in a fuel additive for heavy oil, made using a composition comprising: an oil-soluble metallic compound containing any one metal selected from calcium, barium, manganese, and iron; alcohol; hydrotreated light distillate; paraffin (kerosene); mineral oil; and a nonionic surfactant. The fuel additive for heavy oil, when added in a small amount to a heavy oil, can lower the kinematic viscosity and the flash point of the heavy oil, minimize the occurrence of a residual carbon fraction, dust, a sulfur fraction, or the like, increase the caloric value of the heavy oil, and improve the combustion efficiency during the combustion of the heavy oil.

Claims

1. A fuel additive for heavy oil comprising:

25 to 55 wt. % of an oil-soluble metallic compound containing any one metal selected from calcium, barium, manganese, and iron;

15 to 25 wt. % of an alcohol;

10 to 20 wt. % of a hydrotreated light distillate;

5 to 15 wt. % of kerosene;

5 to 15 wt. % of a mineral oil; and

2 to 8 wt. % of a nonionic surfactant,

wherein the mineral oil comprises at least one selected from the group consisting of hydrotreated heavy paraffinic distillate or hydrotreated light paraffinic distillate, solvent-dewaxed heavy paraffinic distillate, solvent-dewaxed light paraffinic distillate, hydrotreated and dewaxed heavy paraffinic distillate, and hydrotreated and dewaxed light paraffinic distillate.

2. The fuel additive for heavy oil as claimed in claim 1, wherein the calcium-containing oil-soluble metallic compound comprises at least one selected from the group consisting of calcium sulfonate, calcium acetylacetonate, calcium naphthenate, and calcium oxalate.

3. The fuel additive for heavy oil as claimed in claim 2, wherein the calcium sulfonate is calcium alkylbenzenesulfonate, wherein the alkyl of the calcium alkylbenzenesulfonate has 8 to 20 carbon atoms.

4. The fuel additive for heavy oil as claimed in claim 3, wherein the calcium alkylbenzenesulfonate is calcium dodecyl benzene sulfonate.

5. The fuel additive for heavy oil as claimed in claim 1, wherein the alcohol has 1 to 5 carbon atoms.

6. The fuel additive for heavy oil as claimed in claim 5, wherein the alcohol is isobutyl alcohol.

7. The fuel additive for heavy oil as claimed in claim 1, wherein the nonionic surfactant is polyethylene glycol fatty acid ester.

8. The fuel additive for heavy oil as claimed in claim 7, wherein the nonionic surfactant is polyethylene glycol monooleate.

9. A fuel oil based on heavy oil comprising a heavy oil and the fuel additive for heavy oil as claimed in claim 1.

10. The fuel oil based on heavy oil as claimed in claim 9, wherein the content of the fuel additive for heavy oil in the fuel oil is 0.001 to 1 part by weight per 100 parts by weight of the heavy oil.
