Carbon black merupakan material karbon fungsional yang dapat
dihasilkan dari konversi bio-oil tandan kosong kelapa sawit (TKKS), namun
karakteristiknya belum sepenuhnya memenuhi spesifikasi ASTM D1765.
Penelitian ini bertujuan untuk mengevaluasi pengaruh proses slow pyrolysis
terhadap struktur dan morfologi carbon black agar sesuai dengan klasifikasi
standar. Hasil menunjukkan bahwa slow pyrolysis berhasil memperbaiki struktur
dan morfologi carbon black dengan bentuk sferoidal serta struktur turbostratik
yang ditunjukkan oleh rasio parameter kisi c/a sebesar 2,131 hingga 2,855.
Berdasarkan karakterisasi PSA dan BET, diperoleh distribusi ukuran partikel
terkecil sebesar 2 µm dan luas permukaan spesifik terbesar 35–45 m²/g. Selain itu,
analisis SEM-EDX dan FTIR menunjukkan kemurnian karbon yang tinggi.
Seluruh sampel yang dihasilkan memenuhi spesifikasi carbon black grade N990
hingga N550 (ASTM D1765). Carbon black is a functional carbon material that can be produced from
the conversion of oil palm empty fruit bunch (TKKS) bio-oil, but its
characteristics do not fully meet ASTM D1765 specifications. This study aims to
evaluate the effect of slow pyrolysis process on the structure and morphology of
carbon black to conform to the standard classification. The results showed that
slow pyrolysis successfully improved the structure and morphology of carbon
black with a spheroidal shape and turbostratic structure as indicated by the ratio
of lattice parameter c/a of 2.131 to 2.855. Based on PSA and BET
characterization, the smallest particle size distribution of 2 µm and the largest
specific surface area of 35-45 m²/g were obtained. In addition, SEM-EDX and
FTIR analysis showed high carbon purity. All samples produced meet the
specifications of carbon black grades N990 to N550 (ASTM D1765).
