| Summary: | This paper presents a process to utilize oil palm empty fruit bunch (EFB) by thermochemical conversion to
produce carbon-infiltrated biochar, which can be used as an efficient alternative energy source. An integrated process of
pyrolysis and decomposition of pyrolysis vapor was employed by chemical vapor infiltration (CVI) process. For
preparation, raw EFB was made into highly porous biochar by slow pyrolysis process at 500-800°C to provide active sites
for decomposition of pyrolysis vapor. In the general fast pyrolysis process of EFB, the main pyrolysis vapor product will
undergo a secondary decomposition to produce secondary char and gases. In this study, this secondary decomposition is of
interest. Fast pyrolysis of EFB was carried out at 400, 450 and 500°C to produce pyrolysis vapor to be infiltrated within the
pores of biochar substrate and decomposed on its active sites. Secondary decomposition of pyrolysis vapor produced
secondary char, where solid carbon was deposited within the porous biochar substrate, increasing the total carbon content
of the resultant carbon-infiltrated biochar. This process was developed to produce a value-added EFB-derived biochar. One
special application of this product is in steel industry, mainly in their sintering plants; as an efficient alternative energy
source to partially substitute coke breeze |
