Abstract

The invention discloses a rapidly solidified metal passivator and a preparation method thereof. The rapidly solidified metal passivator comprises the following raw materials in parts by weight: 20-30 parts of glucose, 10 to 40 parts of calcium chloride, 40 to 50 parts of boron anhydride, 40 to 50 parts of titanium dioxide, 20 to 30 parts of silicon dioxide, 10 to 20 parts of nickel chloride, 20 to 60 parts of silver nitrate, 10 to 20 parts of aluminium phosphate, 10 to 50 parts of sodium phosphate, 50 to 60 parts of dicyclohexylaminenitrite, 10 to 20 parts of methylcellulose, 20 to 30 parts of methylparaben, 10 to 60 parts of ethylene glycol monostearate, 50 to 80 parts of ammonium dihydrogen phosphate, 10 to 20 parts of molybdate and 50 to 60 parts of potassium sorbate. The preparation method comprises the steps of sequentially adding glucose, calcium chloride, boron anhydride, titanium dioxide, silicon dioxide and nickel chloride into silver nitrate; increasing the temperature for reaction; after cooling, adding the remaining components; and filtering to remove impurities. The rapidly solidified metal passivator can be quickly solidified, and the utilization is convenient.

Description

technical field [0001] The invention relates to a fast-setting metal passivator and a preparation method thereof. Background technique [0002] Metal deactivators are additives that suppress various effects of metals on oil. Metal deactivators have two applications in the oil refining industry. (1) Substances used to inhibit the catalytic effect of active metal ions (copper, iron, nickel, manganese, etc.) on oil oxidation. It is often used in combination with antioxidants in gasoline, jet fuel, diesel and other light fuels, which can improve the stability of oil products and extend the storage period. Commonly used such as N, N'-disalicylidene propylene diamine. (2) In the catalytic cracking of heavy oil, the substances used to inhibit the influence of heavy metals (nickel, vanadium, copper, etc.) contained in the oil on the catalyst activity are commonly used as antimony compounds. [0003] The Chinese patent application with the application number CN200910265418.4 di...
