“…Kwon et al (2012) also reported that the pH increased with increasing carbonization temperature from 7.6 at 400 °C, to 9.7 at 1200 °C. Recently, Hidayat et al (2017) reported that charcoal produced at higher temperatures had a higher pH. The refining degree and charcoal hardness from both kilns had the same values, which showed that the charcoal had excellent characteristics.…”

“…The volatile matter of the charcoal from the traditional kiln (7.05%) was smaller than that from the thermal therapy kiln (9.10%). Hidayat et al (2017) also reported that the volatile matter of the charcoal from four tropical wood species at 800 °C ranged from 14.61% to 22.52%. The fixed carbon of charcoal from the traditional kiln was 82.20%, and 80.19% from the thermal therapy kiln.…”

A modified charcoal kiln was developed for both thermal therapy and charcoal production. The design of a modified kiln for thermal therapy focused on safety and cleanliness, plus the production of good quality charcoal. Two entrances in the kiln were designed for convenient charcoal production and thermal therapy. A barrier wall designed for noxious gases was installed between the adjoining charcoal kilns for safe thermal therapy. Additionally, a fine dust collector was installed to remove the fine dust generated during charcoal production. To verify the safety of the kiln, fine dust and harmful gases, such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and radon (Rn), were measured after the charring process. The quality of the charcoal produced in the thermal therapy kiln was also examined. To evaluate charcoal quality, some physical properties and results from a proximate analysis were evaluated using Korean standards. The measurements of harmful substances and fine dust in the modified charcoal kiln met the criterion of the Ministry of Environment Clean Air Conservation Act in Korea. In addition, there were no noticeable differences in the monthly charcoal characteristics prepared from the thermal therapy kiln, and the charcoal characteristics also met the reference values of the Korea Forest Service.

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

“…Wood from plantation forests is generally inferior to wood from natural forests due to its relatively low durability, low density, and low strength that make it not suitable to be used for structural applications [6,7]. Forest industry sectors should be encouraged to adapt to the use of the species from planted forests, such as by converting it into biomass pellets.…”

Rubberwood (Hevea brasiliensis) and Jabon (Anthocephalus cadamba) are two promising species that is widely planted in industrial plantation and community forests in Indonesia. The objective of this study was to improve the properties of rubberwood and jabon pellets through torrefacation. Torrefaction was performed at a temperature of 300°C and a residence time of 3 min, using Counter-Flow Multi Baffle (COMB) Dryer/Pyrolizer. The properties of torrefied wood pellets as equilibrium moisture content (EMC), density, and heating value. Black pellets were succefully obtained after torrefaction using COMB Dryer/Pyrolizer. The EMC of the black pellets from rubberwood and jabon was 3.54% and 2.85%, which is remarkably lower that their initial EMC of 12.25% and 12.76%, for rubberwood and jabon pellets, respectively. The density of black pellets from rubberwood and jabon and decreased 16.18% and 13.44% compared to control. Torrefaction using COMB Dryer/Pyrolizer also increased high heating value of wood pellets to 18.32% and 79.70%, for rubberwood and jabon pellets, respectively. Consequently, torrefaction using the COMB Dryer/Pyrolizer could improve the bioenergetic properties of jabon and rubberwood pellets.
