Method for producing phase change energy storage wax

Abstract

A method for producing phase change energy storage wax comprises the following steps: refining a Fischer-Tropsch synthetic wax raw material through hydrogenation reaction to obtain Fischer-Tropsch refined wax; primarily separating the Fischer-Tropsch refined wax to obtain a plurality of fractions; selecting a target fraction from the plurality of fractions to carry out sweating treatment to obtainphase change energy storage wax, wherein a sweating device adopted in the sweating treatment is provided with a tubular heat exchanger structure. According to the method, the raw material treatment process is simple, and the production cost is low. By adopting the improved sweating process, the solid-liquid separation efficiency can be improved, the separation effect is improved, and finally theproduct quality is improved.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for producing phase-change energy storage wax. Background technique

[0002] Phase change energy storage technology can solve the contradiction of energy supply imbalance in time and space, improve energy utilization and protect the environment. Phase change materials refer to materials that can absorb or release a large amount of heat energy when they use their own state changes. Phase change energy storage wax is one of the phase change energy storage materials, which can effectively avoid the overcooling and phase separation of inorganic phase change materials, and overcome the shortcomings of inorganic phase change materials that cannot be reused many times. It can be used in many fields such as aerospace, solar energy utilization, power system peak regulation, industrial waste heat recovery, building heating and household appliances.
