| 英文摘要 | With the depletion of energy, energy efficiency received more and more attention. Thermal energy storage (TES) using latent heat of phase change materials can balance the non-equalizing distribution of heat in time and space, and improve energy utilization. In this work, Raw palygorskite (Raw-PAL) was used as the carrier to prepare paraffin/palygorskite shape-stable composite phase change materials (CPCM) through a novel pretreatment by alkalization, acidification and calcination. The Raw-PAL after treatment by the combination of alkalization/ calcination/ acidification (PAL-3) has the maximum adsorption capacity for paraffin. The micromorphology, chemical compatibility, thermal properties and stability of paraffin/PALs were studied. The results of BET and SEM showed that the pretreatment can increase the specific surface area and pore volume of PAL, which has a positive significance to improve the paraffin mass fraction in CPCM. DSC results indicated that the melting enthalpy and melting temperature of paraffin/PAL-3 are 89.2 J/g and 58.55 degrees C respectively. After cyclic test for 300 times, the melting enthalpy of paraffin/PAL-3 can still maintain 96.2% of the initial value and the shape remained unchanged at 80 degrees C for 12 h. The results showed that the paraffin/PAL-3 CPCM was a shape-stable phase change material with potential application. |
