Adsorption of Linear Alcohols in Amorphous Activated Carbons: Implications for Energy Storage Applications

Thermal energy storage using porous materials has become a key technology for improving efficiency and sustainability of heat applications to reduce the carbon dioxide emissions. Choosing adsorbent–fluid working pairs that improve performance an process is challenge due large number possible combinations. The use activated carbons adsorption, purification, as alternative other such zeolites or silica gel promising strategy its low production cost combined good thermochemical performance. In this work, we have explored derived from pyrolysis saccharose coke (CS1000a) thermal storage. For this, considered first four n-alcohols (methanol, ethanol, 1-propanol, 1-butanol) fluids because their enthalpy vaporization. We carried out Monte Carlo simulations with thermodynamical model based on Dubinin-Polanyi theory evaluate interaction energies, microscopic structure, density CS1000a–alcohol pairs. compared these properties commercial carbon, BPL. employed realistic containing functional groups in internal surface simplified without groups. role consequences targeted discussed. CS1000a shows excellent store considerably reduces operational temperatures, making it those market.
