| 概要 |
Commercial activated carbon (AC) has been extensively employing as an adsorbent in the field of the separation process, purification of gases and adsorption cooling system in the last few decades. Rec...ently synthesized activated carbon from mangrove or WPT have higher adsorption uptake than commercial ACs. Moreover, the specific heat capacity of such porous materials is another significant controlling parameter in adsorption characteristics simulation and system design. This research work is focused on the experimental evaluation of the specific heat capacities of raw, carbonized and activated carbon derived from mangrove and waste palm trunk (WPT). The apparatus used in this measurement is a heat flux type differential scanning calorimeter (DSC) from 30°C to 100°C temperature range. The specific heat capacity values are in the range of 0.7 – 1.1 kJ kg-1 K-1 for activated carbons depending on the carbonization condition during synthesis. No phase transition or thermal anomaly is encountered within the measurement conditions.続きを見る
