Production of activated carbon as catalyst support by microwave pyrolysis of palm kernel shell: a comparative study of chemical versus physical activation

Palm kernel shell (PKS), representing an abundantly available oil palm waste in Malaysia, was transformed into activated carbon by microwave vacuum pyrolysis. PKS was first carbonized to produce biochar, followed by an activation process with chemical or water to produce chemically and physically ac...
