“…It also highlights the presence of microspheres or irregular particles, which is a consequence of the low hydrocarbonization temperature [29] that is associated with a range of distinct functional groups such as carbonyl, hydroxyl, carboxylic, ester, and quinone [9]. These structures are more often present in higher running times of hydrocarbonization [1]. This is exemplified by the hydrochar sample obtained at 48 h (HC48) ( Fig.…”

“…As hydrocarbonization proceeds, hydrogen and oxygen compounds are released to the aqueous environment, while the solid phase becomes richer in carbon [11], which consequently explains the decreasing content of hydrogen and oxygen as the hydrocarbonization continues ( Fig. 1) [1]. In conclusion, time is extremely important in the hydrochar synthesis; hence, the hydrochar of 48 h (HC48) had the highest amount of carbon (70.94%) and lower yield mass (40.13%), which are close to the previously reported results [28].…”

“…Large-scale ethyl alcohol production promoted the development of renewable energies related to the wastes of the sugarcane industry. This sector generates a huge amount of bagasse that is already used in heat and energy generation [1], in paper and pulp industries and in biochemical industries [2]. Bagasse can also be used as feedstock for the construction sector, animal food and furfural [2].…”

“…The bagasse is composed by cellulose fibers, lignin and hemicellulose [1]. With its lignocellulosic structure being constituted by macropores (diameter > 50 nm) [7], the sugarcane bagasse is considered as an excellent raw material for carbon.…”

Sugar and ethanol plants produce a large amount of sugarcane bagasse. Such biomass can be the raw material for the production of an adsorbent to uptake CO 2. Thus, this work aimed to evaluate the hydrocarbonization of sugarcane bagasse and to study its use as a CO 2 adsorbent from a simulated flue gas. The temperature of the hydrothermal carbonization (HC) was set at 220 °C, while the operating time ranged from 12 to 48 h. Through the SEM-EDS analysis, the 48-h sample (HC48) was selected for chemical activation with KOH, resulting in activated hydrochar (AHC). The CO 2 and N 2 simple adsorption isotherms were obtained at 50, 70 and 80 °C. The results have shown a higher adsorption at a temperature of 50 °C for both gases. Activated hydrochar clearly preferred CO 2 instead of N 2 at 100 kPa as the maximum adsorption was 1.99 and 0.207 mmol g −1 , respectively. The highest selectivity of CO 2 /N 2 was 12-50 °C, according to the "Ideal adsorbed solution theory" model. Therefore, AHC is clearly an eco-friendly adsorbent that can be used to minimize the resulting release of climate-damaging CO 2 from flue gas to atmosphere.

Indonesia has the largest rubberwood (Hevea brasiliensis) plantation area in the world. Rubberwood is mainly planted for latex production and as latex production declines with age, rubberwood is generally felled. The logging waste and industrial waste of rubberwood-based products could be utilized as raw materials to produce biomass pellets. The quality of biomass pellets can be increased through torrefaction, a thermal process in the temperature range of 200-300°C under an inert atmosphere. This study aimed to evaluate the effect of torrefaction on the characteristics of rubberwood pellets. The torrefaction of rubberwood pellets was conducted using the Counter-Flow Multi Baffle (COMB) reactor, a reactor that could perform torrefaction within a short residence time of up to 5 min. The temperature used in this study was 200°C, 250°C, dan 300°C with a residence time of 3 min. The color change, physical properties, chemical composition, and heating value were evaluated. The results showed that the pellet’s color changed from light brown into black pellets, showing the overall color change (∆E*) of 29,12, 54,27, and 66,71, after torrefaction at 200°C, 250°C, and 300°C, respectively. The equilibrium moisture content of the pellets decreased from 12,25% to 3,54%. The water immersion test also showed that the torrefied pellets have a better hydrophobicity, which is an advantage when pellets are stored in a humid condition. The oven-dry density of pellet decreased from 1,15 g/cm3 to 1,09 g/cm3, 1,04 g/cm3, and 0,96 g/cm3, after torrefaction at temperatures of 200°C, 250°C, and 300°C, respectively. Torrefaction caused a decrease of cellulose and hemicellulose contents, an increase of lignin content, and a remarkable increase in the heating value of 1,71-18,32% with increasing torrefaction temperature. The results proposed that torrefaction using the COMB reactor could provide a great improvement in the quality of rubberwood pellets to improve the additional value of the products.Keywords: black pellet, Counter-Flow Multi Baffle, rubberwood (Hevea brasiliensis), torrefaction
