Method and apparatus for desulfurization of heavy oil using a ferrate(VI)

摘要

A method for desulfurization of heavy fuel oil using ferrate compounds by mixing fuel oil containing sulfur compounds with a solvent and forming a fuel oil solvent mixture, dissolving the sulfur compounds present in the fuel oil solvent mixture. Adding a liquid ferrate solution to the fuel oil solvent mixture produces oxidized sulfur compounds, in solution. An absorbing agent is added to remove the oxidized sulfur compounds from said solution.

1. A method for Desulfurization of Heavy Fuel Oil Using Ferrate comprising the steps of,
mixing fuel oil containing sulfur compounds with a solvent and forming a fuel oil solvent mixture; adjusting the pH of said fuel oil solvent mixture in a range of pH 8.0-10.0); dissolving said sulfur compounds present in said fuel oil solvent mixture; adding a liquid ferrate solution which does not comprise Mn(III) acetate to said fuel oil solvent mixture, producing oxidized sulfur compounds in solution; and adding silica as a catalyst and an adsorbing agent to remove said oxidized sulfur compounds from said solution.
