Grindability of Torrefied Camelina Straw and Microparticle Evaluation by Confocal Laser Scanning Microscopy for Use as Biofuel

Fuels, Journal Year: 2024, Volume and Issue: 5(2), P. 137 - 156

Published: April 11, 2024

This study examined the combined effect of torrefaction and microwave absorbers on improving biomass thermochemical characteristics grindability for heat, power, value-added products. Camelina straw in two grinds, ground (6.4 mm screen size) chopped with biochar addition (0%, 10% 20%), was torrefied a bench-scale reactor at temperatures 250 °C 300 residence times 10, 15 20 min under inert conditions nitrogen-activated. After torrefaction, geometric mean particle size distribution, moisture content, ash bulk densities were determined, grinding performance values without determined compared raw camelina straw. The results showed that diameter decreased after both grinds. specific energy required significantly addition, longer times, increased temperatures. Torrefied had lowest 34.30 kJ °C/20 min. surface morphology by confocal laser scanning microscopy particles indicated (>10%) temperature can create profound distortion, beyond °C, colossal damage carbonized weight fractions produced.

Microwave absorber utilization to improve grinding and particle surface structure characteristics of torrefied switchgrass particles for bioenergy applications

Heliyon, Journal Year: 2024, Volume and Issue: 10(11), P. e32423 - e32423

Published: June 1, 2024

Torrefaction treatment improves biomass grindability by transforming fibrous herbaceous to a more brittle and lighter coal-like material. Microwave assisted torrefaction is promising technology for conversion into energy, fuels, chemicals. The study applied microwave absorbers in the process improve thermochemical characteristics of switchgrass. Switchgrass two particle sizes was torrefied reactor with biochar added as absorber under inert conditions. After torrefaction, geometric mean size distribution selected physical were evaluated, ground chopped without compared those untreated diameter results decreased, specific energy required grinding switchgrass significantly reduced extended residence times at temperature 300 °C. grinding, lowest 32.82 kJ °C/20 min recorded biochar. 10% added/250 °C resulted deep cell wall disarrangement, whereas °C, large surface deformation carbonized weight fractions observed.

Upgrading Fast Pyrolysis Oil with Vacuum Gas Oil by Catalytic Hydrodeoxygenation in Supercritical Ethanol

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(11), P. 9794 - 9803

Published: May 15, 2024

This work demonstrated an effective approach to upgrading bio-oils by pyrolysis bio-oil with vacuum gas oil (VGO) catalytic hydrodeoxygenation (HDO) in supercritical ethanol both hydrogen and formic acid as the situ source. The effects of ethanol, bio-oil/VGO mass ratio, reaction temperature, source, time on co-upgrading VGO over Ru/Al2O3 were investigated this study. Crude bio-oil, crude VGO, co-upgraded oils characterized comparatively for their physical/chemical properties compositions. It was found that optimal conditions at a 4:1 350 °C 2 h catalyst. obtained have improved thermal stability homogeneity, which could be used environmentally friendly sustainable feed large-scale petroleum refinery.

A Comparative Study of Hydrogen-Rich Gas Production from Gasification of Three Agricultural Feedstocks

Published: Aug. 26, 2024

This study comparatively investigated the hydrogen-rich gas generation profiles from agricultural feedstocks (Zea mays stalk, Arundo donax rhizome, and Arachis hypogaea husk) through gasification or pyrolysis-gasification process. The hydrogen production efficiency output of CO were evaluated under varying conditions, including temperatures 800°C to 1100°C steam supplies 1 mL/min 5 mL/min. Pyrolyzed can rapidly (0.60 L/min) release at a temperature 900°C with supply. Furthermore, increasing pyrolysis does not decrease production, while pyrolyzed show higher (an increase 1.64% 10.36%) compared those that have undergone pretreatment. novelty present includes 1) comparison non-pyrolyzed 2) investigation syngas releasing rate feedstock various conditions.
