Charcoal production as raw material
of activated carbon with continuous slow pyrolysis (carbonization) technology
very efficient in terms of the energy efficiency, product quality of charcoal
is produced, the production process in an easy and environment friendly and many
type of outputs is the produced by slow pyrolysis process beside the charcoal
namely syngas, biooil and biomass vinegar,
which are all valued economically. Accurate process control as well as
production capacity of medium-large scale highly profitable to process a large
number of raw materials or that will make activated carbon plant in medium-large
scale with high quality.
The size of activated carbon usually on granul or
powder which is also very suitable with application of the technology. Charcoal
production with JF BioCarbon technology for raw materials of activated carbon will
be in the form of granul with capacity is around 20 tons to 70 tons per day
which is processed by steam activating so that it would be activated carbon.
With raw materials of charcoal is produced then activated carbon plant with
capacity 6 - 25 tonnes per day can be made. Charcoal from coconut shell and palmkernel shell are the most common used in
the activated carbon production because its hardness. Iodine number is other
parameter the quality of activated carbon besides its hardness. With steam
activation, the iodine number that can be reached around 1000 while when
combined with chemical activation then the iodine number that can be reached
above 2500.
By setting up the operational process condition such
as temperature and residence time then charcoal with high fixed carbon can get
and after the process conditions has been obtained for charcoal product with
that specification that is desired then the hot charcoal can immediately feed
into the rotating kiln activation unit without cooling beforehand, so that will save
energy consumption significantly especially in the steam activation process.
Syngas from pyrolysis will be used in the activation process to produce steam
and keep the temperature of activation. Excess syngas after being used in
process activation, then can be used to generate electricity or other energy
source.
