Abstract

The invention discloses an anti-coking synthetic aromatic heat-conducting oil, which mainly consists of the following components: synthetic aromatic base oil, amine antioxidant, phenolic antioxidant, detergent, and dispersant; wherein the content of the synthetic aromatic base oil should be Not less than 95wt%; said synthetic aromatic base oil: initial boiling point>300°C, density>0.98g / cm3, pour point<-28°C, residual carbon<0.05%, acid value<0.03mg KOH / g, copper Chip corrosion is less than grade 1 (tested according to GB / T 5096, 100°C, 3h). The anti-coking synthetic aromatic heat transfer oil of the present invention not only has good thermal stability, but also has moderate viscosity and high heat conduction and mass transfer efficiency, and has outstanding and substantial significance for reducing boiler fuel consumption.

Description

technical field [0001] The invention relates to an organic heat carrier, in particular to a synthetic aromatic heat-conducting oil with anti-coking performance. The invention also provides a preparation method of the anti-coking synthetic aromatic heat-conducting oil. Background technique [0002] Heat transfer oil has the performance of anti-thermal cracking and chemical oxidation, good heat transfer efficiency, fast heat dissipation, and good thermal stability. Under almost normal pressure conditions, very high operating temperatures can be obtained. It can greatly reduce the operating pressure and safety requirements of the high-temperature heating system, and improve the reliability of the system and equipment; it can meet the process requirements of heating and cooling at different temperatures in a wider temperature range, or use the same heat conduction in the same system The oil realizes the process requirements of high temperature heating and low temperature coolin...
