Method for deep desulphurization of hydrocarbon fuels

摘要

Method for deep desulphurization of hydrocarbon fuels includes following steps: (1) treatment of a hydrocarbon fuel under the condition of its mixing with gaseous oxidant selected from the group consisting nitrogen monoxide, dry air, ozone and a mixture of at least two of said reagents in order to oxidize sulfur-containing compounds presented in said fuel, and with a fine-dispersed adsorbent based on montmorillonite in order to adsorb oxidized sulfur-containing compounds, and (2) separation of spent adsorbent together with adsorbed oxidized sulfur-containing compounds from refined fuel.

1. A method for deep desulphurization of hydrocarbon fuels, comprising the steps of:
firstly, mixing a fine-dispersed adsorbent based on montmorillonite with liquid hydrocarbon fuel to form a suspension comprising only in the liquid hydrocarbon fuel and the adsorbent; secondly, continuously mixing a gaseous oxidant with the suspension in order to oxidize sulfur-containing compounds present in the liquid hydrocarbon fuel and to adsorb the oxidized sulfur-containing compounds from the liquid hydrocarbon fuel; and removing spent adsorbent and adsorbed oxidized sulfur-containing compounds from the suspension; wherein oxidation of the sulfur-containing compounds occurs on catalytically active surfaces of the adsorbent.
