Abstract Agricultural residues can be converted to value-added products such as fuel pellets. Bio-based additives, including alkali lignin, glycerol and l -proline were used for binding formulation of canola hull fuel pellets. The binding formulation was optimized to produce pellet with the mechanical durability (by drop test) of 99%, relaxed density of 1,110 kg/m3, and energy density of 18,603 MJ/m3. l -proline showed the best performance in the enhancement of mechanical properties of pellet wh...

Supercritical water is an excellent green solvent for many chemical reactions such as oxidation, gasification, pyrolysis and liquefaction. It is a promising reaction medium for the generation of hydrogen from biomass through a series of degradation reactions, such as hydrolysis, steam reforming, water–gas shift reaction, hydrogenation and methanation. Supercritical conditions at temperatures greater than 374 °C and pressures above 22.1 MPa are found helpful to degrade a variety of biomasses and ...

Abstract Supercritical water gasification has been a promising technique for hydrogen production using several lignocellulosic biomasses and organic wastes. Various organic wastes such as sewage sludge, lignocellulosic biomass, municipal solid waste, industrial effluents and cattle manure that have been used as feedstocks for supercritical water gasification. With the objective of hydrogen production from alternative and less explored resources, Canadian Athabasca bitumen was used as a feedstock...

The aggregating usage of fossil fuels, rising demand for energy, fluctuating fuel prices, and increasing emissions of greenhouse gases are some of the concerning factors contributing to a shift in the interest from fossil fuels to biofuels. Biofuels are carbon-neutral sources of energy as the CO2 emissions resulting from their combustion is utilized by the plants during photosynthesis leading to no net increase in atmospheric CO2 levels. It is indispensable to focus on the new approaches to the ...

Abstract Pinecone is a lignocellulosic forest residue with value-added industrial importance in terms of energy and materials production. Although promising, pinecone has received inadequate attention as a biofuel feedstock for thermochemical conversion. Water above its critical temperature (T C ≥ 374 °C) and critical pressure (P C ≥ 22.1 MPa), termed as supercritical water, has high kinetic energy and densities similar to that of gases and liquids, respectively. When employed in gasification, s...

Abstract The stability of turbulent non-premixed biogas flame was studied experimentally by varying the fuel composition (i.e., changing the carbon dioxide content in the fuel, which is mainly composed of CH 4 and CO 2 ) and altering the fuel nozzle geometry. The fuel was discharged through a central nozzle surrounded by a co-axial airflow passing through a low-swirl (25°-angle vanes) generator. The results revealed that the biogas flame stability limits are highly sensitive to fuel composition ...

In the present work, we describe a simple method to fabricate dual-phobic fluorosilane-coated polydimethylsiloxane/camphor-soot/polydimethylsiloxane (FPCP) composite surfaces. The surface morphology and silane treatment provide the needed texture on the FPCP composite surface to demonstrate superamphiphobicity in the air and oleophobicity in the underwater environment. High-resolution field emission-scanning electron microscopy (FESEM) imaging of the FPCP composite surface illustrates the top su...

Abstract Humic acid is a model compound of sewage sludge that occurs as a result of decomposing organic matter. Supercritical water gasification of humic acid was performed at a temperature, feed concentration and reaction time of 600 °C, 15 wt% and 75 min, respectively with variable concentrations (5–15 wt%) of Lewis acid metal chloride catalysts. The non-catalytic gasification of humic acid resulted in H2 yield (0.79 mol/kg), total gas yield (1.59 mol/kg), carbon gasification efficiency (2.2%)...
