Abstract

The study aimed to determine the effects of adhesive content on rubber wood charcoal briquette characteristics. Wood charcoal was produced using a double-drum retort kiln at > 500°C.  Wood charcoals were crushed into powder and then mixed with tapioca adhesive of 5%, 10%, and 15%. The charcoal-adhesive mix was then pressed using a hydraulic press machine. For comparison, rubber wood biomass briquettes were also produced using wood particle-adhesive mix with similar adhesive content.  Biomass and charcoal briquettes characteristics as physical properties (density and water absorption), chemical properties (ultimate analysis, and FTIR analysis) and energy properties (calorific value) were evaluated.  The results showed that density ranged between 0.52-0.56 g/cm3, water absorption of 6.54-7.47%, C content of 82.67-84.41%, H content of 3.28-3.60%, N content of 0.67%-0.74%, and calorific value of 30.76-32.86 MJ/kg.  The results of FTIR analysis showed changes in the spectrum of the wave band on the functional groups OH, CH, C≡H, C=C, and C=O, indicating the decomposition of the chemical components of rubber wood due to pyrolysis.  The results prove that increasing the adhesive content can reduce the quality of briquettes.  Based on physical, chemical, and energy properties, charcoal briquettes with 5% adhesive showed better characteristics than briquettes with 10% and 15% adhesive content, showing water absorption of 6.54%, C content of 84.41%, H content of 3.28%, and heating value of 32.86 MJ/kg. Keywords:  adhesive content, charcoal briquette, pyrolysis, rubber wood waste, tapioca starch

Abstract

As the largest natural rubber producing country after Thailand, Indonesia has an immense potential of rubberwood sources. Rubberwood waste is suitable for raw materials to produce charcoal through pyrolysis method, providing more value-added. Kilns used in the pyrolysis process are diverse. The different kiln used will affect the characteristics of the charcoal produced. This study aimed to determine the characteristics of rubberwood charcoal produced using box-type kiln and dome-type kiln. The characteristics analyzed were charcoal yield, moisture content, ash content, volatile matter, and fixed carbon. The results showed dome and box-type kilns produced charcoals with different characteristics. Char yield of charcoal produced using box and dome-type kilns was 15.82% and 14.21%. Charcoal produced using box-type kiln has a moisture content of 4.51%, ash content of 3.06%, volatile matter of 18.10%, and fixed carbon of 74.33%, while charcoal produced using dome-type kiln has a moisture content of 6.16%, ash content 2.52%, volatile matter of 6.26%, and fixed carbon of 85.06%. The charcoal characteristics met the SNI 01-1683-1989 standard, except for the moisture content of charcoal produced using dome-type kiln.
