- CO2 and CH4 gas are green house gasses which contribute to earth surface temperature increase (global warming) post industrial period, sea level rise and the other environment impacts. Some efforts have already performed to reduce green house gassses emission. One of those is by adsorption method. This research was done with a purpose to proof CO2 and CH4 gas physisorption capacity by phenolic-resin porous carbon using static volumetric method. The porous carbons have various internal surface area and pore structure. The research was conducted in several stages, namely assembling a highpressure adsorption test equipment by static volumetric method, characterization of porous carbon (internal surface area, pore volume, pore size distribution, SEM, FTIR), sample preparation and testing of porous carbon adsorption capacity for CO2 gas and CH4 gas either on wet or dry state. Dry porous carbon adsorption test performed on a different system temperatures (273K, 298K, 308K and 318K), while in wet porous carbon carried out at a temperature of 277K to see the possibility of gas hydrate formation. With reference of low pressure gas adsorption datas, isosteric heat of adsorption can be calculated specifically for this type of adsorbate and adsorbent (porous carbon). Then, the obtained isotherm curves were evaluated using the Toth equation. This research revealed that among all porous carbons samples, the highest CH4 adsorption capacity on 3.5 MPa and 298 K belongs to mesopore carbon MS1 (capacity 8.88 mmol/g) whereas the highest CO2 adsorption capacity on 3.4 MPa and 298 K belongs to mesopore carbon MS2 (capacity 25.78 mmol/g). Afterward, in order to increase CO2 and CH4 adsorption capacity, there are other options by creating gas hidrat or capillary condensation. The best option for CH4, is adsorption by wet porous carbon MS2 (gas hydrate) on 277K and 3.8 MPa (capacity 15.5 mmol/g). The best option for CO2 is adsorption by dry porous carbon (capillary condensation) on 273K and 3.8 7MPa (capacity 172 mmol/g).
