Title:
SOLAR PHOTOTHERMAL POWER GENERATION HEAT-TRANSFER AND HEAT-STORAGE MEDIUM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/205759
Kind Code:
A1
Abstract:
A solar photothermal power generation heat-transfer and heat-storage medium, comprising a nitric acid fused salt heat-storage medium and a carbon nanotube composited in the nitric acid fused salt heat-storage medium; in the solar photothermal power generation heat-transfer and heat-storage medium, the mass percent of the carbon nanotube is 0.1%~1%, and the diameter of the carbon nanotube d≥10nm. The heat-transfer and heat-storage medium is prepared by grinding and homogeneously mixing a sodium nitrate and potassium nitrate fused salt with the carbon nanotube to obtain a raw material powder; heating and melting the raw material powder and preserving heat for at least 1h to obtain a molten mixture; and cooling the molten mixture to an indoor temperature and crushing and homogenously mixing the mixture.
