| 제목 | Thermal effect on dynamic charging of methane on anthracite based- carbon monolith |
| 초록 | Recently adsorbed natural gas (ANG) has been identified as the most promising low-pressure (30.0 - 40.0 bar) alternative ofthe compressed natural gas (CNG) for vehicular use. However in order to successfully implement this technology, the filling and discharging characteristics of the adsorbent bed must be well understood. Abrupt temperature changes that occur during adsorption and desorption can retard the system performance significantly. In this work thermal effects associated with the dynamic charging of methane in an adsorbed natural gas (ANG) cylinder filled with activated carbon monoliths, have been studiedat two different charging rates (60.0 and 90.0 ml/min)by measuring the change in temperature. At a high charging rate (90.0ml/min), the filling time was about 1.3 min for the cell volume of 1 ml and the temperature of bed at the center increased about 9.1 ºC. However, in the case of a low charging rate(60.0 ml/min), the filling time was expanded to 2.1 min and the maximum temperature difference was reduced to 7.5 ºC. The monoliths were prepared from activated carbon powder and carboxy-methyl-cellulose (CMC) as a binder. All the samples were characterized by nitrogen adsorption/ desorption, SEM, FT-IR and XPS etc. A delivered methane amount was dynamically measured 10 times in a 50 cc methane reservoir at 303.15 K and 40 bar in a gravimetrical dynamic adsorption apparatus. The fluctuations of temperature and pressure in the reservoir were also measured during cyclic operations. |
