Abstract
A method for producing a clean gasoline from a light hydrocarbon fraction is disclosed. The method includes two main steps including desulfurization of a light hydrocarbon fraction along with enhancing octane number of the desulfurized light hydrocarbon fraction. The octane number of the desulfurized hydrocarbon fraction is enhanced by applying a hormone-modified additive.
Claims15
A method for producing a clean gasoline from a light hydrocarbon fraction, the method comprising:
- forming a mixed phase by putting in contact the light hydrocarbon fraction with an oxidant in presence of a metal spinel-type oxide catalyst, the mixed phase comprising a desulfurized hydrocarbon phase and a non-desulfurized hydrocarbon phase, the non-desulfurized hydrocarbon phase comprising sulfur-containing compounds and the metal spinel-type oxide catalyst;
- producing a determined separated phase by separating the desulfurized hydrocarbon phase from the mixed phase, wherein the determined separated phase comprises a sulfur content of less than 1 percent;
- obtaining a hormone-modified additive, comprising
- producing a COOH functionalized additive by dispersing an additive in an acidic mixture, the acidic mixture including one or more of HNO3 and H2SO4, the additive including carbon nanotubes;
- and
- obtaining the hormone-modified additive by adding a hormone to the COOH functionalized additive under stirring for 1 to 10 hours;
- and
- producing the clean gasoline through enhancing octane number of the desulfurized hydrocarbon phase by putting in contact the desulfurized hydrocarbon phase with the hormone-modified additive.
