Abstract

Mangrove leaves (ML) were pre-carbonized at low carbonization temperature, ball milled for 36 hours and followed by sieving to obtain powder (SACG) with particle size less than 53 micron and then pelletized into green pellets (GP). A multi-step heating profile which was previously proven suitable for producing 'crack-free' carbon pellets (CP) from the GP of the SACG from oil palm empty fruit bunch (EFB) was found to be suitable for producing CP from the SACG of the ML. Themogravimetri results on the SACG show that in comparison to the SACG-EFB, the SACG-ML decomposed with a lower rate of weight loss within a wider range of the temperature region and it maximum rate occurs at the slightly higher temperature. X-ray diffraction results found that both types the SACG retain their lignocellulosic structure. The density of CP produced up to the carbonization temperatures of 700°C and 1000°C respectively were found to be in the range from 0.94 to 1.03 gcm-3 and 0.98 to 1.28 gcm -3 for the ML and EFB samples respectively. X-ray diffraction results on the CP found that both type of samples have turbostratic structure, with their interlayer spacing d002 decrease with increasing carbonization temperature; that is from 3.79 Å to 3.43 Å for the ML samples and 3.82 Å to 3.68 Å for the EFB samples.
