Improved natural gas storage with adsorbed natural gas technology (ANG) using activated carbon from pineapple crown

Natural gas considered as alternative fuel that still has the enough availability in Indonesia. One of the utilizations of natural gas is ANG technology which based on adsorption principle. The adsorption of natural gas occurs in isotherms condition at 27 °C, 31 °C, and 35 °C and using low pressure up to 9 bar. Activated carbon were used from bio-based carbon from pineapple crown with IOD number 1337 mg/g and surface area 1190.799 m2/g which compared to commercial activated carbon with iod number 1727 mg/g. Bio-based carbon were prepared through chemical and physical activation. This study begins with making preparation for the ANG (Adsorbed Natural Gas) technology will be used, degassing process, measuring the void volume, storage capacity, and delivery capacity. The maximum storage of pineapple crown activated carbon reached 0.0397 kg/kg at 9 bars 27°C with desorption efficiency of 43.82% and commercial activated carbon reached 0.0429 kg/kg at 9 bar and 27°C and desorption efficiency of 43.82%.
