Characteristics of Leucaena leucocephala and Sesbania grandiflora Woods

Wood sample taken from the trunk of 3 year old Leucaena leucoceaphala tree was found to have a medium density and EMC and a higher heating value. Its cellulose and carbon contents were high and the ash content was low. Similar sample taken from Sesbania grandiflora plant had a low density and FMC. Compared to Leucaena leucocephala wood, it had lower heating value, less cellulose, more lignin, a lower carbon content Ind higher ash and silica contents. On the basis of the physical and chemical charaeleristics, Leucaena leucocephala wood is considered to be a superior fuel wood and a better raw material for gasification and pyrolysis.
