The main objective of this research was to study the adsorption of gaseous fuel in porous rubber. The porous rubber was produced by using defrost technique from freezing latex which prepared rubber remain porous. Aluminium silicate crystal formed by reaction between sodium silicate and aluminium sulfate, were acted as stabilizer. This study used the paraffin wax and carbon powder as the enhancement adsorption agent of hydrocarbon gas (LPG and methane) and hydrogen gas, respectively. The amount of enhancement adsorption agent was varied from 0, 20, 40, 60, 80 and 100 phr and the temperature was varied from -10, 0, 10, 20 and 30 ํC. The results represented that adsorbed gas increased with the increasing of enhancement adsorption agent and the decreasing of temperature. The potential porous rubber was prepared by mixing of 100 phr paraffin wax and adsorption was-10 ํC. The maximum LPG adsorption was 6,120 mole LPG/mole rubber (1.47x10[superscript -1] kg LPG/kg rubber) at 0.23 hl duration. For methane, the maximum adsorption was 7,055 mole methane/mole rubber (5.64x10[superscript -2] kg methane/kg rubber) at 0.17 h. duration. For hydrogen adsorption, the potential porous rubber was mixed with 100 phr carbon. The maximum adsorption was 1,681 mole hydrogen/mole rubber (1.68x10[superscript -3] kg hydrogen/kg rubber) at 0.08 h. duration. From the study, it was concluded that the adsorption of LPG, methane and hydrogen depended on amount of adsorption agent, temperature and duration time. For the desorption of gaseous fuel, it was found that time of desorbed gas decrease when increasing amount of enhancement adsorption agent and decreasing of adsorbed temperature.
