A Study on Preparation of Peach Charcoal Full-spectrum Sunlight Utilization Material and Its Solar Evaporation Performance
In order to determine the influence of carbonization on solar absorption and seawater evaporation in biomass materials,porous peach charcoal was prepared with anaerobic high-temperature carbonization of waste peach wood,the chemical characterization and appearance were analyzed,and the solar evaporation performance was tested.The results showed that the material featured ultra-fast water transmission and full-spectrum sunlight absorption capacity,and the absorption rate was 94.84％in the full wavelength range of sunlight(250～2 500 nm).Under one solar irradiation,the seawater evaporation rate of PWC reached 1.56 kg·(m2·h)-1,and the evaporation rate remained above 1.50 kg·(m2·h)-1 after 30 cycle stability tests.
