Absorption of Tar Content in Producer Gas using Used Cooking Oil in a Packed-bed Column

<span lang="EN-US">The tar content in producer gas may cause crusting on the engine if it is utilized as a fuel gas, thus needs to be removed. This study aims determine liquid phase mass transfer coefficient process of removing from packed-bed contactor column. carried out continuously using used-cooking oil absorbent. was by contacting product cacao pod-husk gasification at temperature range 491-940<sup>o</sup>C certain counter-current flow rate with column Raschig ring packing bed.
