4 Mei 2017 ABSTRACT The objective of this study
was to produce briquette from the mixture of pyrolysis products.
Palm shell was pyrolyzed at a temperature of 400°C for
2 h holding time and heating rate of 10°C/min.
The biochar and bio-oil ratio was prepared at 3:1 weight percentages
for briquette. The viscosity of bio-oil was improved to increase
the bonding forces. The characterization of biochar, bio-oil,
coal and briquette were analyzed and presented in this study.
The density and compressive strength of briquette were, respectively,
found to be 0.94 gcm-3 and
3.20 Nmm-2. The shatter and water resistance of briquette were established
to be 97 and 96 wt. %, respectively. The high heating value
(HHV)
of briquette was 29.6 MJkg-1 greater than that of Malaysian sub-bituminous
coal 24.6 MJkg-1. It implies that the briquette
produced is stable, durable and qualitative. Therefore, it can
be concluded that the briquette can substitute coal in some
applications. Keywords: Biochar; bio-oil;
briquette; pyrolysis ABSTRAK Objektif kajian ini adalah
untuk menghasilkan briket daripada campuran produk pirolisis.
Isirung kelapa sawit telah dipirolisis pada suhu 400ºC selama
2 jam dengan kadar pemanasan 10ºC/min. Nisbah peratus berat
abu dan minyak bagi briket yang terhasil adalah 3:1. Kelikatan
minyak bio telah ditambahbaik untuk meningkatkan daya ikatan.
Ciri abu, arang batu dan briket telah dianalisis dan dibincang
dalam kajian ini. Ketumpatan dan kekuatan mampatan briket adalah
0.94 gcm-3 dan
3.20 Nmm-2. Rintangan pecahan dan air briket yang tercapai masing-masing
adalah 97 and 96 % bt. Nilai pemanas tinggi (HHV)
briket adalah 29.6 MJkg-1 dan lebih tinggi daripada arang batu
bitumen Malaysia, iaitu 24.6 MJkg-1. Ini menunjukkan bahawa briket
yang terhasil adalah stabil dan tahan lama. Kesimpulannya, briket
yang terhasil boleh menggantikan arang batu dalam kegunaan tertentu. Kata kunci: Abu biologi; briket; minyak biologi; pirolisis RUJUKAN Abdullah,
