Abstract
Variables used in this investigation are wood species (Jelutung and keruing), carbonization temperatures (400°C and 500°C) and activators (CaCl 2 , MgCl 2 and ZnCl 2 ). The parameters observed were yield, moisture content, ash content, iodine and benzene adsorption. This investigation reveals that the highest yield obtained from keruing wood, CpCl 2 activator at carbonization temperature of 400°C. The lowest moisture content charcoal obtained by using processing temperature of 500°C. Jelutung wood with MgCl 2 activator had the lowest moisture content compared to that of ZnCl 2 activator. The highest iodine adsorption obtained when using ZnCl 2 activator and carbonization temperature of 500°C (for keruing wood). It was found that high benzene vapor adsorption charcoal could be produced by using ZnCl 2 activator, carbonization temperature 500°C and Jelutung wood as raw material. Sunbury, H.M. (1923).
