Abstract
This study is a scaled-up experiment for carbon cloth made of the pristine-palm-kernel shell studied previously at the laboratory level. Prototypes of activated carbon filter (cylindric net, 40 cm height & 18 cm diameter) were prepared from the activated palm-kernel carbon cloth. The ammoniac adsorption capacity test was carried out within six closed rooms with the individual dimension of 120 cm × 90 cm × 220 cm. The ammonia vapor samples were determined by UV-Vis spectrophotometric method. Each room contained 2.8 × 10−5 M of ammonia vapor at ambient temperature, (28 + 1)°C atmospheric pressure. The activated carbon mean-weight of (179 + 5) g or equivalent to (0.1 + 0.003) g per cm2. The optimum time of adsorption was 60 minutes and the mean adsorption capacity of the carbon filter was 1.78 × 10−5 M per 1720 cm2 of carbon cloth. The carbon filter prototype absorbed 60.6% of ammonia vapor in the closed room. The adsorption remained constant, although the absorbent and time were expanded.
