Hydrogenation synthesis heat transfer liquid and preparation method thereof

Abstract

The invention relates to a hydrogenation synthesis heat transfer liquid and a preparation method thereof. The invention belongs to the field of chemical heat transfer oil preparation. The heat transfer liquid is characterized in that the heat transfer liquid is prepared by adding a functional additive to deep hydrogenation base oil. The functional additive is prepared from the raw materials of, by mass: 20% of a high-temperature antioxidant alkyldiphenylamine, 10% of an anti-aging agent 2,6-di-tert-butyl-phenol, 25% of a detergent sulfurized alkylphenol calcium, 35% of a detergent medium-base-value synthetic calcium sulfonate, 5% of a KX-ZJ-01 high-temperature decoking agent, and 5% of a KX-ZS-03 hydrogenation scale inhibitor. The molecular components are pure, and organic impurities such as S, N, O, and heavy metals influencing the quality and service life of the heat transfer oil are not introduced. The product quality is excellent, heat transfer performance is good, and the heat transfer liquid is safe and environment-friendly.

Description

technical field [0001] The invention relates to a hydrogenated synthetic heat transfer fluid and a preparation method thereof, belonging to the field of preparation of chemical heat transfer oil. Background technique [0002] At present, in the normal production process in the chemical industry, it is often necessary to heat the reactor, etc., so the use of heat transfer oil has become inevitable in the chemical industry. Of course, not only in the chemical industry, the use of heat transfer oil is becoming wider and wider. It It has excellent heat conduction performance, and at the same time, through the conduction of heat transfer oil, the objects that need to receive heat are heated evenly, ensuring the normal progress of reactions, etc. However, the current heat transfer oil on the market has a short service life. Reduce the content of organic impurities such as S, N, O and heavy metals, thus resulting in short service life and easy to cause environmental pollution. Co...
