The use of fossil fuels in human activities such as motorcycles has led to an increase in the concentration emitted in the atmosphere. Various efforts and methods such as adsorption using activated carbon have been developed and applied to reduce the emission. Therefore, this study focuses on the characteristics and performance of bamboo-activated carbons in the adsorption of motorcycle flue gases. This was carried out using different grain sizes (z) of activated carbons AC-M1, AC-M2, and AC-M3 for grain sizes of z≤250, 250<z≤420, and 420<z≤590 microns, respectively, which were derived from swat bamboo and carbonized at a temperature of 750 ○C. Furthermore, physical activation was applied by heating the charcoal at the same temperature under a nitrogen flow rate of 150 mL/min nitrogen. The Thermogravimetric (TGA), scanning electron microscopy (SEM), and adsorption isotherm tests were employed for the characterization of activated carbons. Additionally, the performances of activated carbons for motorcycle flue gas adsorption (CO2, CO, and HC) were carried out by a motorcycle emission test. According to the results, activated carbon AC-M1 produced the best characteristics and performance for adsorption of motorcycle flue gas, as it has a pore volume of 0.135 cm3/g, a specific surface area of 244.69 m2/g, and a nitrogen adsorption capacity of 87.047 cm3/g. These characteristics prove to have good adsorption efficiencies at 100 %, 87.30 %, and 100 % for adsorption of CO2, CO, and HC, respectively.

“…The precursor and activating agent to be used were swat bamboos and phosphoric acid (H3PO4), respectively. In previous work, it was reported that the cellulose, lignin, and hemicellulose contents of swat bamboo were 44.22%, 22.99%, and 14.97%, respectively [37]. Bamboo was made become small sizes and dried until no weight change.…”

The activation process is the final stage in the manufacturing of activated carbon that can be carried out physically or chemically. This paper focuses on characterizing the surface properties of activated carbons from Gigantochloa verticillata bamboo that are chemically activated at 750°C under different impregnation ratios (IRs) of 1:1, 2:1, and 3:1. The activated carbons produced were denoted as IR1-AC, IR2-AC, and IR3-AC for impregnation ratios of 1:1, 2:1, and 3:1, respectively. Characterizations include TGA, SEM, and adsorption isotherm tests. The results of the research show that variation of the impregnation ratio yielded fluctuated content of proximate elements and surface properties of activated carbons. The highest fixed carbon of 75.69% and the lowest ash of 13.10% were obtained by IR2-AC. The highest surface area of 511.10 m2/g and pore volume of 0.561 cc/g was obtained by IR3-AC and IR2-AC, respectively. The activated carbon pores are distributed in micropores and mesopores areas with average pore diameters of 1.245, 2.494, and 1.984 nm for IR1-AC, IR2-AC, and IR3-AC, respectively. The existence of the pores can be found on the surface morphology of activated carbons.

The experimental study is the best way to find out the characteristics of activated carbon (AC) due to its very difficult definition based on its structural formulation or chemical analysis as an effect of its high degree of imperfection in the crystal structure. This experimental study’s objectives are to investigate the characteristics and the adsorption capacities of activated carbon generated from used brewed coffee. The carbonization procedure took place at a temperature of 600 °C. After being made into pellets and powder, the charcoal was heated to 600 °C and activated with the help of 150 mL of nitrogen flowing per minute. Thermogravimetric analyzer (TGA), scanning electron microscopy (SEM), and the adsorption isotherm test were all utilized in the characterization process. The results showed that for pelleted activated carbon (AC-Plt) and powdered activated carbon (AC-Pw), respectively, both activated carbons had average pore diameters in the mesopore category of 4.39 and 4.93 nm. In comparison to AC-Pw, AC-Plt has a larger specific pore surface area (105.857 cm3/g) and pore volume (0.164 cm3/g). The adsorption capabilities of AC-Plt, which has a bimodal pore size distribution, are greater than those of AC-Pw for nitrogen, CO2, and methylene blue. In this investigation, it was discovered that pelleted activated carbon was more suited for the adsorption of nitrogen, CO2, and methylene blue. HIGHLIGHTS The used brewed coffee was successfully converted into powdered and pelleted activated carbons using nitrogen as an activator agent through physical activation The use of natural binder to produce pelleted activated carbon undergoes pyrolysis during the activation process, producing gas that acts as an activating agent (e.g., CO2) so that nitrogen and CO2 work simultaneously and more effectively to develop more activated carbon pore structures Pelleted activated carbon has a higher specific pore surface area of 105.857 cm3/g, pore volume of 0.164 cm3/g, and better adsorption capabilities for nitrogen (75.252 cm3/g), CO2 (1.554 mmol/g) and methylene blue (1.215 mg/g) adsorptions than powdered activated carbon GRAPHICAL ABSTRACT
