Problems solved by technology

However, the hydrodesulfurization on the traditional hydrodesulfurization catalyst also deoxidizes the phenolic hydroxyl groups, which fails to achieve the purpose of desulfurization while retaining phenolic compounds. The purpose of oil desulfurization without dephenolation is of great significance to the utilization of phenolic oil

preparation example Construction

[0033] The method of the present invention has no special limitation on the preparation method of the carrier. In the process of preparing the carrier, various additives that need to be added conventionally, such as scallop powder, acidic binder, etc., can be added, and the amount of the additive is not particularly limited. Those skilled in the art can determine the amount of additives added according to actual needs.

[0034] The method of the present invention is not particularly limited to the concentration of the solution containing the active metal component elements, as long as the content of the active metal component of the desulfurization and non-removing phenol catalyst prepared by using the solution containing the active metal component elements It only needs to meet the aforementioned scope of the present invention. The method of the present invention has no special limitation on the type of the solution containing the active metal component elements, for example,...

preparation example 1

[0048] This preparation example is used to prepare the desulfurization and non-removal phenol catalyst of the present invention, and the specific method is as follows:

[0049] After 450g of zinc oxide, 50g of aluminum oxide, and 15g of scallop powder were mixed evenly, 3% by weight of dilute nitric acid was added to make the dry-mixed sample appear paste-like, and the paste-like sample was extruded into strips by a screw extruder, and then dried in a blast dryer Dry overnight at 120°C, place in a muffle furnace and bake at 400°C for 6 hours to obtain ZnO-Al 2 o 3 carrier. Then, prepare the supported catalyst for desulfurization without dephenolization by equal volume impregnation method: take 5g of nickel nitrate and dissolve it in 7ml of deionized water, add 20g of the aforementioned ZnO-Al 2 o 3 The carrier was stirred for 30 minutes and soaked overnight at room temperature (25°C). The solid product was dried at 120° C. for 6 hours to obtain a catalyst precursor for des...

Abstract

The invention relates to the field of oil refining, and discloses a desulfurization treatment method of phenol-containing oil and desulfurated phenol-containing oil produced by the method. The method includes contacting the phenol-containing oil with a desulfurizing non-dephenolizing catalyst to perform treatment of desulfurizing without dephenolizing under a hydrogen condition. The desulfurizing non-dephenolizing catalyst comprises a carrier and an active metal component supported on the carrier. The carrier is one or at least two of zinc oxide, aluminum oxide and silicon oxide, and the active metal component is at least one of nickel, copper, palladium, platinum and ruthenium, wherein, based on the total weight of the desulfurizing non-dephenolizing catalyst, the content of the carrier is 80-98 wt%, and the content of the active metal component is 2-20 wt%. The hydrogen condition refers to that the reaction is carried out in a hydrogen atmosphere under normal pressure. The method in the invention can decrease the sulfur content to the utmost degree under a premise of decreasing the phenols content as little as possible, so as to enhance economic benefits to a greater degree.

Description

technical field [0001] The invention relates to the field of oil refining, in particular to a method for desulfurizing phenol-containing oil and the desulfurized phenol-containing oil prepared by the method. Background technique [0002] Coal tar contains a large amount of phenolic compounds. If the coal tar is directly hydrogenated and upgraded, on the one hand, the phenolic compounds will be hydrodeoxygenated, resulting in a decrease in added value, and at the same time, it will increase the hydrogen consumption of the hydrogenation process; on the other hand, The water generated by the deoxygenation of phenolic compounds may lead to the aggregation of the active metal center of the catalyst, affecting the activity of the catalyst. It can be seen that the rational utilization of phenolic compounds in coal tar is of great significance. [0003] At present, the conventional way to upgrade phenolic compounds in coal tar is to dephenolize coal tar to obtain crude phenols or f...
