Embodiment 1-1

[0042] The total amount of anti-coking alkylbenzene heat transfer oil is 1000Kg, which is made of alkylbenzene base oil 974Kg, T5344Kg, 22464Kg, T1065Kg, T1224Kg, T1559Kg. The alkylbenzene base oil: initial boiling point>320°C, density>0.83g / cm3, flash point>190°C, carbon residue<0.05%, acid value<0.03mg KOH / g, pour point<-55°C, Corrosion of copper sheet is less than grade 1 (tested according to GB / T5096, 100°C, 3h).

Embodiment 1-2

[0046] The total amount of anti-coking alkylbenzene heat transfer oil is 1000Kg, which is made of alkylbenzene base oil 980Kg, L574Kg, T5014Kg, T1225Kg, T1547Kg. The alkylbenzene base oil: initial boiling point>320°C, density>0.83g / cm3, flash point>190°C, carbon residue<0.05%, acid value<0.03mg KOH / g, pour point<-55°C, Copper sheet corrosion is less than grade 1 (tested according to GB / T 5096, 100°C, 3h).

Embodiment 1-3

[0050] Take 972Kg of alkylbenzene base oil, heat it to 120°C, and keep it for 1 hour to remove water and light components in the base oil. Analysis shows that the water content in the base oil is 280mg / Kg. Add solid additives: T5163Kg and T5013Kg, stir and dissolve completely. Continue to cool down to 80° C., L574Kg, T1078Kg, T154 and T155 each 5Kg, stir, and mix evenly to obtain the finished anti-coking alkylbenzene heat transfer oil.

Abstract

The invention discloses anti-coking alkylbenzene synthesis heat conduction oil. The anti-coking alkylbenzene synthesis heat conduction oil mainly comprises the following ingredients: alkylbenzene base oil, amine antioxidants, phenolic antioxidants, clearing agents and dispersing agents, wherein the content of the alkylbenzene base oil is not lower than 95 in percentage by weight; the initial boiling point of the alkylbenzene base oil is greater than 320 DEG C; the density of the alkylbenzene base oil is greater than 0.83g / cm(3); the flashing point of the alkylbenzene base oil is greater than 180 DEG C; the carbon residue of the alkylbenzene base oil is smaller than 0.02%; the acid value of the alkylbenzene base oil is smaller than 0.02mg KOH / g; the pour point of the alkylbenzene base oil is smaller than minus 55 DEG C; and copper corrosion is smaller than 1 level. The anti-coking alkylbenzene synthesis heat conduction oil has the advantages of high clearing performance, high dispersing performance, low high-temperature degradation, high oxidation resistance, high coking resistance, high sedimentation resistance and long service life. The self-cleaning property is high, and the high cleanliness of the anti-coking alkylbenzene synthesis heat conduction oil can be kept for a long time.

Description

technical field [0001] The invention relates to a heat-conducting oil, in particular to an alkylbenzene synthetic heat-conducting oil with anti-coking properties. The invention also provides a preparation method of the alkylbenzene synthetic heat-conducting oil. Background technique [0002] Organic heat carrier mainly refers to the organic medium used for heat conduction, among which heat transfer oil is the most widely used, covering various industries such as petrochemical, textile printing and dyeing, wood processing, food and pharmaceuticals, and paper making. Heat transfer oil is also known as heat transfer oil, and its official name is heat carrier oil (GB / T4016-83). Heat transfer oil is a heat transfer medium. High temperature, good heat transfer effect, energy saving, convenient transportation and operation. [0003] Heat transfer oil has the performance of anti-thermal cracking and chemical oxidation, good heat transfer efficiency, fast heat dissipation, and good ...
