Abstract
Energy recovery from processing wastes of
agricultural products is a solution to their management
issues and a means of energy production. In addition, it
contributes to the reduction of deforestation. The objective
of this study is to develop a method of agroforestry residues
carbonization. The residues used to consist of the shell of the
doum palm (hyphaenethebaica) and the rice husk.
Carbonization is in partial combustion, and the device used
is a metal furnace made up of three (3) stages. The peaks of
temperatures, mass and energy yields, and the quality of the
coal (fixed carbon rate) were determined at each stage of
the carbonized. The mass yields obtained for stages 3, 2, and
1 are 66.41%, 42.60%, and 21.57% for the shell of the doum
palm and 46.94%, 67.19% 24.83% for the rice husk. The
energy yields are 82.41%, 57.05%, and 30.97% for the shell
of the doum palm and 56.1%, 74.58%, and 26.66% for the
rice husk. The coal quality (fixed carbon rate) for the same
stages 3, 2, and 1 is 35.32%, 44.42%, and 52.32% for the
shell of the doum palm and 32.55%, 30, 43%, and 30.75%
for the rice husk. The cycle time is 9.03h for the shell of the
doum palm against 11.22h for the rice husk. This study
shows that the shell of the doum palm produces better
quality charcoal compared to the rice husk and that the
charcoal obtained at stage 1 (
) can be used not only for
gasification but also for direct home use.
