Embodiment 1

[0078] Hydrotreated straight-run diesel oil (which contains 500ppmw elemental sulfur, 0.28wt% organic sulfur, and a density of 0.85KG / L) according to figure 2 method of oxidative desulfurization. The reaction conditions are as follows:

[0079] Catalyst: molybdenum-based Mo(VI)

[0080] Response time: 30 minutes

[0081] Temperature: 80°C

[0082] Pressure: 1kg / cm 2

[0083] During the extraction, 93 kg of bis-imidazolidine was used as electron donor. The extraction at 110°C, 1kg / cm 2 pressure and 0.1h -1 LHSV performed.

[0084] The material balances for the oxidation and extraction steps are shown in Tables 1 and 2, respectively. Desulfurized diesel contains 40 ppmw sulfur.

Abstract

A process wherein an electron donor agent is provided for the decomposition of sulfones and sulfoxides formed after the oxidative desulfurization of a sulfur-containing hydrocarbon stream.

Description

[0001] related application [0002] This application claims the benefit of US Patent Application No. 13 / 181,043, filed July 12, 2011, the disclosure of which is incorporated herein by reference. [0003] field of invention [0004] The process of the present invention involves the removal of oxidized sulfur compounds following oxidative desulfurization of crude or distillate oils, or integrated hydrodesulfurization / oxidative desulfurization. More specifically, it relates to a method for decomposing remaining sulfones and sulfoxides after oxidative desulfurization. [0005] Background of the invention [0006] Crude oil is the world's major source of hydrocarbons used as fuel and petrochemical feedstock. Although the composition of natural oils or crude oils varies significantly, all crude oils contain sulfur compounds, and mostly nitrogen compounds, which also contain oxygen, but the oxygen content of most crude oils is low. Typically, the sulfur concentration in crude oil i...
