Abstract Massive amounts of waste tires are generated globally posing disposal and recycling challenges. Waste tires were gasified in subcritical and supercritical water to study their degradation behavior during syngas production. The process parameters including temperature (325 °C to 625 °C), reaction time (15 min to 60 min) and feed concentration (5 wt% to 20 wt%) were optimized to maximize gas yields from waste tires. The highest total gas yields (34 mmol/g), hydrogen yields (14.4 mmol/g) a...

Abstract Water borne pathogens pose a great threat to the health-care system and their mitigation poses a formidable challenge prompting researchers to find innovative and effective methods for pathogen control. Large scale implementation technologies for wastewater treatment need to be economical and facile. We have utilized industrial waste from citrus fruits to develop green nano-biocomposite materials. Green nano-biosynthesis methods are known to be cost effective, non-toxic and environment ...

Abstract Integration of metals into the biomass matrix has been found to be an alternate strategy to the conventional catalysts that are prone to deactivation. Different metals like Ni (0.98 mol/kg), Ru (0.76 mol/kg) and Fe (0.83 mol/kg) are separately impregnated into banana pseudo-stem to analyse their impact on H2 yields. In-situ gasification of metal impregnated biomass was conducted over sub/- and supercritical water range of 300–600 °C, with 1:10 biomass-to-water ratio for 60 min. X-ray di...

Abstract Pyrolysis/gasification have proved to be promising conversion techniques to convert biomass into fuels. The current research work focuses on impregnation of Ru and Fe into banana pseudo-stem to study kinetics, pyrolytic behaviour and their impact during pyrolysis through thermogravimetric analyser (TGA). Samples weight loss were analyzed by TGA at four different heating rates (5–20 °C min−1) over the temperature range of 30–900 °C. Isoconversional models such as Flynn-Wall-Ozawa (FWO), ...

Abstract Sub and supercritical water oxidation (Sub- CWO & SCWO) technology has gained attention over the past few years due to near complete conversions at shorter residences times. A pharmaceutical sample containing variety of analgesics, antibiotics, antipyretics, antifungal, β-blockers and drug intermediates contributing to overall total organic carbon (TOC) of 2017 ± 49 mg/L was collected from a nearby pharmaceutical industry for this research. The sample was subjected to sub and supercriti...

Abstract Hydrothermal flame is produced in an aqueous environment beyond the thermodynamic critical properties of water. It is an interface developed at the contact of oxidant and fuel in supercritical water and depends on the operating parameters. In-situ diffusion-limited hydrothermal flames were generated in a novel supercritical flame reactor designed by the National Aeronautics and Space Administration (NASA) at Glenn Research Center to investigate the impacts of oxidant flow rate and tempe...

This research work aims to develop a biomaterial entrapped with iron nanoparticles by green synthesis method in which biomass act as both reducing and capping agent. Iron nanoparticles embedded in Citrus limetta peels were characterised using ICP-MS for determination of metal loading, XRD, XPS for crystallinity and oxidation states, TEM followed by FESEM-EDS for particle size and morphology. Sizes of nanoparticles were found to be in the range of 4–70 nm. Batch experiments were conducted to stud...

Nanocatalysts and their integration into biomass have gained importance over the past few years. This research gave insights on impregnation of Ni salts in bagasse and mosambi peels with the variation of pH at 30 °C for 48 h. The highest loading was attained at pH 6.5 for bagasse and 5.2 for mosambi peels. The impregnated metal biomass samples were subjected to in situ hydrothermal gasification over the temperature range 300–500 °C. The transition of Ni2+ to metal nickel nanoparticles during in ...
