Bottom ash from palm oil mills is used for this investigation. Characteristic tests and CO 2 adsorption processes have been conducted [26, 31, 32], and bottom ash is acceptable for the CO 2 adsorption method [33]. This is due to the lowest inlet velocity, the longer the contact time between the adsorbent and CO 2.
