Abstract
The invention discloses modified high-temperature conduction oil, which is a blend of base oil alkane, high-temperature and low-temperature antioxidant, and anticoking agent. The modified high-temperature conduction oil is composed of 90 to 95 parts by weight of base oil alkane, 2 to 5 parts by weight of high-temperature antioxidant, 1 to 5 parts by weight of low-temperature antioxidant, and 1 to 3 parts by weight of anticoking agent. The preparation method comprises the following steps of: performing dealkylation, dewatering, vacuum distillation, filtration, purification and an advanced mixing process on the base oil; adding the used high-temperature and low-temperature antioxidants and an anti-corrosion anticoking agent and performing complex mixing. In the heat-transfer medium, the modified high-temperature conduction oil has the advantages of high heat value, excellent heat steadiness, quick heat transfer rate, uniform heating, high control precision, innocuity, odourless, low operation pressure, security and convenience; the highest operating temperature of the oil can reach 320 DEG C and the service life is over 3 years.

Anticoking agent 1-3 part.
Described high temperature modified conduction oil is characterized in that preferred prescription comprises according to parts by weight:
90 parts of base oil alkanes;
5 parts of high-temperature anti-oxidant;
2 parts of low temperature antioxidants;
3 parts of anticoking agents.
A kind of preparation is as the method for the above-mentioned high temperature modified conduction oil of claim, the step that it is characterized in that it is: at first base oil is adopted take off light, dehydration, vacuum is purified, is filtered advanced calendering process and carries out refining, add again adopt the high and low temperature antioxidant, the anti-tartar anticoking agent is composite forms.
By technique scheme, the present invention has following advantage:
High temperature modified conduction oil of the present invention belongs to the organic heat carrier class, have in heat-transfer medium that calorific value height, Heat stability is good, heat transfer rate are fast, homogeneous heating, temperature-controlled precision height, nontoxic, odorless, working pressure is low and advantage such as safe facility, maximum operation (service) temperature reaches more than 3 years up to 320 ℃ work-ing life.
Embodiment:
The invention discloses a kind of high temperature modified conduction oil, it is the blend of base oil alkanes, high temperature and low temperature antioxidant, anticoking agent, comprises according to parts by weight:
Base oil alkanes 90-95 part;
High-temperature anti-oxidant 2-5 part;
Low temperature antioxidant 1-5 part;
Anticoking agent 1-3 part.
The method of above-mentioned high temperature modified conduction oil is: at first base oil is adopted and take off gently, dehydration, vacuum is purified, advanced calendering process such as filtration carry out refining, add again and adopt height, the low temperature antioxidant, composite forming such as anti-tartar anticoking agent and metal passivator, composite additive with excellent heat stability function, select by the proportioning to composite additive kind and amount, to reach the deterioration by oxidation that delays the thermal oil thermal response, prolong the thermal oil purpose in work-ing life, and finally improving production unit, be equipped with advanced laboratory apparatus in the time of technology, carry out effective thermal stability determination, more to objectively respond quality product and characteristics.The step that it is characterized in that it is: at first base oil is adopted take off light, dehydration, vacuum is purified, is filtered advanced calendering process and carries out refining, add again adopt the high and low temperature antioxidant, the anti-tartar anticoking agent is composite forms.
Principle of the present invention is: high temperature modified conduction oil adopts advanced calendering process such as taking off light, dehydration, vacuum purifications, filtration and science is selected materials and the proportioning additive: high temperature and low temperature oxidation inhibitor, anticoking agent improve resistance of oxidation by correlation proportion; And rationally matches alkane in the base oil, naphthenic hydrocarbon, the character of three kinds of hydro carbons of aromatic hydrocarbon, ratio difference and allocates, to improve the ability that hot tearing is gone bad.High temperature wherein, low temperature oxidation inhibitor can effectively delay the pitch that the oxidizing reaction retrogradation in the thermal oil operational process produces; Anti-tartar, anticoking agent can make the oxidative pyrolysis and the polymkeric substance that produce under the hot conditions effectively dissolve, and do not form the coking material of coking, guarantee the cleaning of heat-conducting oil system furnace wall and good heat-transfer effect is provided.
