✦ Synopsis

Abstract

Several batches of chars were prepared from palm shell by carbonization in a flow of nitrogen using a fixed‐bed reactor. Palm shell was carbonized at temperatures of 500, 600, 700, 800 and 900 °C for 1 h to study the effects of carbonization temperature on char yield and its porosity. The prepared chars were characterized for the micropore volume using CO~2~ adsorption while the meso‐ and macropore volumes were analyzed using a mercury porosimeter. The char yield was around 25% and is comparable with yields reported from other lignocellulosic materials. The results show that carbonization temperature has a significant effect on the micro‐ and mesopore volumes. However, it has negligible effect on the macropore volume.

BACKGROUND: Manure is the main waste of raising livestock, when spreading in soils can cause surface and ground water pollution. The management of manure is associated with emissions of greenhouse gases and odours. Dry manure contains at least 45% of carbon. This is an attractive characteristic for
