“…The surface of AHF was smoother whereas some fissures were observed on the surface of AHFC and AHFT which could be due to the disintegration of hemicelluloses and cellulose from the lignocellulosic matrix on hydrothermal carbonization and pyrolysis. 32 The porosity increased in AHFC and AHFT compared to the raw fiber and the pores were clearly visible in both the hydrochar and the pyrochar with the appearance of droplet like depositions. The SEM images of adsorbents after adsorption (AHFCU and AHFTU) showed the filling of the pores with the metal ion.…”

“…The HHV for juice processing residues varied from 16.53 to 18.72 MJ kg −1 (Table 4), which is higher than the HHV reported for other lignocellulosic biomass, such as rice husk, ponkan peel, sugarcane bagasse, elephant grass, cotton stalk, wood sawdust and arecanut husk. 4,17,27,[50][51][52] On the other hand, the LHV reflects in practice the maximum amount of bioenergy that can be produced from biomass combustion, and the bioenergy potential recoverable from juice processing residues varied from 15.24 to 17.03 MJ kg −1 . By combining a considerable bioenergy potential with a great abundance of these feedstocks, it is posited that juice processing residues have the potential to compete favorably with low-rank coals.…”

“…The bulk density of orange bagasse is higher than other well-known biomass residues such as rice husk, coconut shell, ponkan peel, sugarcane bagasse, elephant grass, cotton stalk and arecanut husk. 4,17,[49][50][51][52] Usually, a higher bulk density value implies low costs for storage, transportation and handling. Another important factor connected with handling and transportation is the bioenergy density, which represents the available potential bioenergy relative to the biomass volume.…”

“…As noted in Table 5, FVI for apple bagasse, cashew-apple bagasse and orange bagasse are comparable to typical biomass for bioenergy purposes. 4,17,[50][51][52] Therefore it is expected that juice processing residues (higher FVI values) possess better biofuel properties in terms of flammability and heat generation. 54,55 In an effort to obtain information about fossil fuel equivalence and potential CO 2 retention, both the energy density and the emission factor for conventional liquid fossil fuels (e.g., petroleum, diesel fuel, fuel oil and gasoline) were used following the procedure found in related literature.…”

This work aims to investigate the energy-related characteristics of apple bagasse, orange bagasse and cashew-apple bagasse to identify their potential as bioenergy feedstocks. For this, a detailed characterization was performed, including proximate analysis, ultimate analysis, atomic molar ratio, heating values, chemical composition, bulk density, bioenergy density, fuel-value-index (FVI), fossil fuel equivalence and potential CO 2 retention. Proximate composition revealed moisture, volatile matter, fixed carbon and ash contents in the range of 7.8-9.3%, 67.1-74.2%, 16.2-22.0% and 1.6-5.7%, respectively. Typical values for carbon (44.8-49.9 wt.%), hydrogen (5.5-6.6 wt.%) and oxygen (40.1-44.2 wt.%), with low sulfur (< 0.1 wt.%) and nitrogen (< 2.7 wt.%) contents were found. In regard to bulk density (237.7-554 kg m −3 ) and bioenergy density (3.93-10.1 GJ m −3 ), juice processing residues have substantial values when compared with well-known lignocellulosic residues. Recoverable energy potential from the juice processing residues varied from 15.24 to 17.03 MJ kg −1 . From FVI analysis, apple bagasse is expected to be more suitable for thermochemical processing. Orange bagasse, on the other hand, has the highest equivalent in fossil fuel volume. Consequently, its use as solid fuel may lead to a decrease in CO 2 emissions from reference fuels.

“…Hydrothermal carbonization (HTC) is a promising thermochemical process that converts wet biomass like animal manures into solid fuel and functionalized materials by using high temperatures and saturated vapor pressures [1][2][3]. Traditionally, lignocellulosic biomasses have been mainly used as a feedstock for HTC to produce solid fuel with properties similar to lignite coal [4]. In the last few years, however, HTC technology has been used for numerous non-lignocellulosic biowastes [5,6].…”

Hydrothermal degradation of β-estradiol and oxytetracycline at selective reaction severities

et al. 2020

View full text Add to dashboard Cite

Hydrothermal carbonization (HTC) is a thermochemical process that produces biofuels and carbon-based materials from wastes; the solid product is commonly known as hydrochar. However, the fate of common pharmaceutical products during HTC has not been explored extensively. Knowledge on degradation pathways for emerging contaminants is important for further application of hydrochar, especially for water purification and soil amendment. Therefore, the objective of this study was to investigate the degradation of two emerging pollutants (i.e., oxytetracycline and 17β-estradiol) with HTC temperature, residence time, and initial chemical states. High-performance liquid chromatography and gas chromatography-mass spectroscopy (GCMS) were used to analyze the levels of degradation of oxytetracycline and β-estradiol and the secondary products generated due to their primary degradations, respectively. The results showed that the degradation of oxytetracycline and β-estradiol did not depend significantly on the HTC temperature and residence time. However, their degradation depends significantly on the initial pH of the solution. The maximum degradation of oxytetracycline and β-estradiol was observed at 84.1 ± 2.9% and 100% at initial pH 8 and pH 3, respectively. GCMS results showed that stable acidic compounds (such as benzoic acid and furoic acids) were produced due to the degradation of both oxytetracycline and β-estradiol in most of the experimental conditions.
