[0017] Preparation of Organic Peroxides by Air Oxidation

[0018] The raw material is a hydrotreated diesel oil to be oxidized and desulfurized, and its sulfur content is 810 μg / g. Measure 300 milliliters of diesel oil into a three-necked flask, and add 1 milliliter of cumene hydroperoxide as an initiator. The three-necked flask was placed in an oil bath, connected with a condenser, a thermometer and a bubbling device, then heated up and fed with air at a flow rate of 50 ml / min, and started timing when reaching the reaction temperature, and stopped the reaction after 20 hours of reaction. The total peroxide concentration was determined by indirect iodometric method, and its molar concentration was 5.8mol / L.

[0019] Oxidation of sulfur compounds in diesel

[0020] The prepared diesel oil containing organic peroxide and the diesel oil to be oxidized are mixed at a volume ratio of 1:2 to prepare oxidation reaction raw materials. The silica-supported Mo-P oxide catalyst is mad...

Abstract

The invention belongs to coal processing, petroleum processing, and petroleum chemistry technology field and relates to oxo process high efficiency deprivation for sulfur compound in distillate oil. It oxidizes part of distillate oil under the condition of 80-150 degree centigrade and 0.1-5MPa lasting for 10-50 hours to oxidize alkyl aromatics to organic peroxide. Mixing the distillate oil containing organic peroxide and the distillate oil waiting for oxidization, send into the fixed bed reactor that is filled with load type molybdenum-phosphorous oxides catalyst granule. Under the situation of the temperature between 40-90 degree centigrade and normal pressure, using organic peroxide as oxidizing substance, the sulfur compound in distillated oil would be oxidized into sulfoxide or sulphone, which could be extracted by solution or adsorbed by solid adsorbent to realize deep de-sulfurization. The invention has broad application prospect.

Description

technical field [0001] The invention belongs to the technical fields of coal processing, petroleum processing and petrochemical industry, and relates to the efficient removal of thiophene sulfur-containing compounds in petroleum distillates (gasoline, kerosene, diesel oil, etc.) compound removal. Background technique [0002] The sulfur in gasoline and diesel will form SOx after being burned by automobile engines, which is not only harmful to human health, but also the direct cause of acid rain after being discharged into the atmosphere. Therefore, it is necessary to try to remove the sulfur in the fuel in order to fundamentally eliminate its pollution to the atmosphere. [0003] The traditional desulfurization method is to selectively react hydrogen with sulfur-containing compounds under high temperature and high pressure conditions and the action of transition metal sulfide catalysts, and reduce the sulfur atoms in organic sulfur-containing compounds to hydrogen sulfide, ...
