| dc.description.abstract | Biochar is the result pyrolysis of biomass waste, in this case the waste of oil palm
empty fruit bunch. The qualities of the final biochar product will vary depending
on the pyrolysis technique method. The morphology of a biochar can be observed
with a Scanning Electron Microscope (SEM), the surface area and pores can be
observed with a Brunneauer Emmet Teller (BET), and the functional groups
present in the biochar can be observed with a Fourier Transform Infrared (FTIR)
analysis. This study aims to look at the characteristics and get the best retort
method in producing high quality oil palm empty fruit bunches biochar. Analysis
of the surface and functional groups of biochar that has been made is carried out
at the Badan Riset dan Inovasi Nasional (BRIN). The results showed variations in
the surface properties of biochar produced using various retort techniques. The
results of the SEM-EDX analysis showed that biochar created using the closed
retort method had a higher carbon content in both retort procedures and formed a
larger and more porous surface pore shape than biochar produced using the open
retort method. The results of the BET analysis showed that the surface area of the
biochar produced by the closed retort method has a value 54,462 m2
/g is 7 (seven)
times greater than that of the biochar produced by the open retort method, which
has a value of 7,65 m2
/g. The pore sizes, which are classified as micropores,
15,376 Å for the closed retort method and 19,241 Å for the open retort method.
The results of the FTIR analysis showed that biochar with the open retort method
had 15 peaks with 9 functional groups and biochar with the closed retort method
had 11 peaks with 8 functional groups. | en_US |
