“…In China, many manufacturers are subsidized by local governments to encourage them to utilize agricultural and forestry waste to produce BBF, which is also being gradually adopted for industrial power generation and residential heating [7,8]. Several researchers have investigated the use of BBF as a heat source for heating supply, as an alternative to coal [9,10]. Typically, BBF is used in a furnace originally designed to burn coal, to provide the heat needed for the tobacco curing [11,12].…”

A new system for providing heat for the flue-curing of tobacco was developed by modifying the conventional direct combustion of biomass fuel (bio-fuel) such that the energy stored in the fuels was fully utilized. The system consisted of an integrated furnace with a heat dissipation structure for combusting and gasifying bio-fuel including solid fuel as well as combusting the generated gas, and a heat exchanger with a special flue pipe layout. The new device was tested through experiments in different tobacco-growing areas, using the controlled direct combustion of coal and biomass fuel for flue-curing in a bulk curing barn. The results showed that the distribution of temperature in the longitudinal section of the new system exhibited a regular temperature transition pattern corresponding to the solid fuel and gas combustion areas. The amount of carbon monoxide in the flue gas at the chimney exit indicated that the burning of the biomass briquette fuel was more complete, with less than 1.7% carbon monoxide generated. The thermal efficiencies of the biomass briquette fuel and firewood were 55.26 and 53.17%, respectively, which were higher than that of coal (49.52%). The newly developed integrated furnace would be well suited for tobacco curing in tobacco-growing areas, and could be used commercially for drying agricultural products on different scales.

“…The biomass materials contained hemicellulose, cellulose, and lignin, with the capacity of being decomposed into fixed carbon content. 52 In addition, the activated carbon GSC was synthesized following a combination routine route, which includes chemical activation, carbonization, and physical activation. These stages featured changes in the supramolecular properties investigated, and TGA, as shown in Figure 3A, demonstrates the first raw material decomposition at temperatures reaching 104.8 C. This phase indicated the release of water content, as GSC materials mainly decompose at a range of 200 C-350 C, with a 35.45% weight loss.…”

“…57 The activated carbon derived from biomass materials also produces some natural content in low intensity, including some minerals, for example, magnesium, calcium, sodium, potassium, depending on the composition of cultivated soil. 52,63 Furthermore, the limited amount of chlorine and zinc is observed as by-products of ZnOCl, which is not removed by imperfect washing. The values in Table 3 are in line with the conclusions from EDX analysis, which indicate high carbon and oxygen content of GSC samples, alongside the small amount of impurities.…”

Carbonization and activation have been exploited as an economic and efficient approach toward the production of porous activated carbon monolith derived from green stem of cassava (GSC). In addition, ZnCl 2 was used as a chemical activator agent at various concentrations, therefore serving as a key factor in the development of porous carbon. The carbonization process (N 2) was integrated with physical activation (CO 2), and then N 2 sorption, scanning electron microscopy, X-ray diffraction, energy dispersive X-ray were examined to evaluate the specific surface area, pore structure characteristic, morphology structure, crystallinity, and the surface element, respectively. Furthermore, cyclic voltammetry was used to measure the electrochemical performance, through a two-electrode system in 1M H 2 SO 4. Therefore, the synthesized porous activated carbon exhibits a micropores-mesopores combination, and the optimized sample demonstrated nanosheet and nanofiber structures. The results show a high electrochemical behavior in 1M H 2 SO 4 electrolytes, by the electrodes, with specific capacitance, energy, and power densities of 164.58 F g −1 , 22.86 Wh kg −1 , and 82.38 W kg −1 , respectively. This route confirms the opportunity of using novel GSC in the production of porous carbon monolith with nanosheet/nanofiber structure for supercapacitor applications.

Conversely, the difference between both is that capacitors store and deliver energy incredibly quickly, while batteries have an ability to store high energy densities and also high voltages. 4 However, the main challenge of supercapacitor is related to the energy density entry through the narrow gap of batteries. Several electrode materials have been developed and suggested to improve energy density, power density, and cycle life of supercapacitor, 5 and three types were identified. These were then classified into carbonaceous

The behaviour of ash of fuel affects its thermal efficiency when in use. The ash analyses of bio-coal briquettes developed from lean grade coal and torrefied woody biomass have received limited intensive study. Therefore, the present study aims at analysing the ashes of briquette made from lean grade coal and torrefied woody biomass using blended coal tar pitch and molasses as the binder. Bio-coal briquettes were produced from coal and torrefied biomass in various hybrid ratios. Ashing of various briquettes was done in a muffle furnace at 850 °C for 3 h. Mineral phases of the ash were identified using an X-ray Diffractometer (XRD), while the mineral oxides were obtained using an X-ray Fluorescence Spectrometer. The AFT700 Furnace was used with its AFT700 software to evaluate the ash fusion temperatures of the ashes. The XRD patterns look similar, and quartz was found to be the dominant mineral phase present in the raw coal and bio-coal briquettes. The SiO2 (57–58%), Al2O3 (19–21%), and Fe2O3 (8–9%) were the major oxides observed in the ashes. The final fusion temperatures of the ashes range from 1300–1350 °C. The compositions of the ashes of the bio-coal briquettes are classified as detrital minerals. It was concluded that the addition of torrefied biomass (≤ $$10\%)$$ 10 % ) and blended binder ($$\le $$ ≤ 15%) to coal gave a negligible impact on the ashes of the resultant bio-coal briquettes.
