Comparative study of natural gas adsorption isotherms on KOH and H3PO4 palm kernel shells porous activated carbon

Sustainable energy of Natural Gas (NG) has been an increasingly valuable and advantageous fossil fuel as it produces a cleaner combustion, and efficient consumption. Compressed Natural Gas (CNG) storage method and its utilisation has caused several problems due to high cost of installation for exten...
