Abstract

Biogas impurities is a major problem related to its heating value and feasibility of conversion to small-scale electrical energy. Adsorption is believed as one of potential method of biogas purification. This process conducted in porous material whose surface active properties, such as activated carbon with an acid or base activator. Laboratory experiments and mathematical quantification were carried out to study the drying process of Gamal (Gliricidia Sepium) stem as a source of biomass that were widely grown in the local area of livestock / biodigester. Determination of the drying process parameters and mass transfer parameters were approached using three drying models, namely (1) Dincer and Dost models, (2) Bi-G correlation approach, and (3) Fick law equation.
