Problems solved by technology

When converting mercaptans, the fixed-bed deodorization process is still used, which can only be used to convert mercaptans in catalytic gasoline, and cannot convert mercaptans well for hydrogenated gasoline.
[0010] Chinese patent application 00109631.1 discloses a method for converting mercaptans contained in light oil products, which also uses a fixed-bed catalytic oxidation method to make light oil products mixed with air or oxygen pass through a fixed-bed reactor Catalyst bed, under the action of the catalyst, oxygen reacts with the mercaptan contained in the light oil to generate disulfides. The active components of the catalyst are nanoscale transition metal element oxides, perovskite type rare earth composites Oxides or spinel oxides; although this method injects 1.5 to 2 times the theoretical amount of air or oxygen into the light oil, it can prevent the problem of excess air or oxygen taking away part of the oil and gas, but if The shorter the contact time of the light oil with the catalyst bed, the less efficient the conversion of mercaptans

Abstract

The present invention relates to a method for supplementing oxygen into hydrocarbon oil. Said method is characterized by that in the hydrocarbon oil a liquid oxygen-supplementing agent using tert-butyl hydroperoxide as effective component can be added, and in the flowing process the tert-butyl hydroperoxide in the oxygen-supplementing agent can be dissolved in the hydrocarbon oil, and when the hydrocarbon oil in which the tert-butyl hydroperoxide is dissolved in passed through the catalyst bed layer which is placed in the fixed bed reactor and has catalytic property of decomposing tert-butyl hydroperoxide, under the action of catalyst the tert-butyl hydroperoxide in the hydrocarbon oil can be decomposed, and can release out nascent active oxygen. The active component or said catalyst is compound of manganese.

Description

technical field [0001] The invention belongs to the field of refined processing of petroleum products, and in particular relates to a method for supplementing oxygen into hydrocarbon oil. Background technique [0002] The hydrocarbon oil referred to in the present invention includes refined petroleum products including liquefied petroleum gas, naphtha, gasoline, aviation kerosene, lamp kerosene and diesel oil. Naphtha, gasoline, aviation kerosene, lamp kerosene and diesel oil can be collectively referred to as light oil products. In petroleum refining, crude oil can be divided into light distillate oil, heavy distillate oil and vacuum oil residue through atmospheric and vacuum distillation. Light distillate oil includes gasoline, kerosene, diesel oil, etc., and heavy distillate oil includes various A lubricating oil fraction, cracking feedstock (i.e. vacuum distillate or wax oil). In order to obtain more light oil products, heavy distillate oil and residual oil are further...
