Abstract

The invention relates to a method for preparing a normal temperature oil desulfurizer. The preparation method comprises the steps of preparing a zinc oxide mixture, preparing a ferric nitrate solution, preparing mixed liquid of silver and copper, squeezing, drying and baking. The normal temperature oil desulfurizer prepared from the method provided by the invention can not only remove hydrogen sulfide and a part of mercaptan sulfur in oils, but also has a good removal effect on elemental sulfur that is difficult to remove, the range of applicable oil raw materials is wide, and the oil corrosion problem caused by a variety of sulfides can be solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of petroleum product production. More specifically, the present invention relates to a preparation method of normal temperature oil desulfurizer. 【Background technique】 [0002] In the production process of oil products such as naphtha and aviation kerosene, excessive active sulfide is an important factor that leads to the unqualified metal corrosion detection of oil products. Products that fail the corrosion test generally cannot be transported to the storage tank, otherwise it will seriously affect the normal production of the enterprise, and the sulfide emitted from the combustion of this oil as fuel will also pollute the environment and endanger human health. [0003] It is generally believed that the sulfides that can cause corrosion among many sulfides are mainly elemental sulfur, hydrogen sulfide and small molecule mercaptans. At present, most of the sulfides in these oils can be removed by alkali...
