Oxidative Conversion of Chars Generated from the Fixed-Bed Pyrolysis of Wood Torrefied at Different Temperatures and Holding Times

Autor: Carmen Branca, Colomba Di Blasi

Publikováno v: Processes; Volume 11; Issue 4; Pages: 997

Fixed-bed pyrolysis of torrefied spruce wood, for a heating temperature of 800 K, results in char yields between about 27–57 wt% (versus 23 wt% for untreated wood), depending on both pre-treatment temperatures (533–583 K) and holding times (8–2

Dynamics and products of potato crop residue conversion under a pyrolytic runaway regime - Influences of feedstock variability

Autor: Carmen Branca, Antonio Galgano, Colomba Di Blasi

Potato, ranked third among food crops, gives rise to huge amounts of plant residues largely unutilized owing to the presence of toxic compounds. The fundamentals of the pyrolytic runaway of these residues are investigated for a packed bed heated at a

Modeling the effects of cultivar and harvest on the decomposition kinetics of potato crop residues

Autor: Carmen Branca, Colomba Di Blasi

Publikováno v: Fuel. 339:127419

Thermogravimetry and kinetic analysis is carried out of the decomposition of potato crop residues, integrated by model compound measurements. Compared with other herbaceous by-products, conversion takes place at lower temperatures, gives rise to high

Kinetic assessment of the thermal decomposition of hemp fiber and the impact of pretreatments

Autor: Carmen Branca, Colomba Di Blasi

Motivated by green building applications (bio-composite and insulation materials), thermogravimetric and kinetic analysis is applied to investigate the thermal degradation of cleaned hemp fibers (F), obtained after water retting and mechanical decort

Enhancement and inhibition of the oxidation rates of pyrolytic chars from wood loaded with potassium compounds

Autor: Carmen Branca, Colomba Di Blasi

Publikováno v: Fuel. 331:125886

The oxidation is studied of chars produced from the highly exothermic packed-bed pyrolysis, carried out at moderate temperatures, of potassium-loaded beech wood (additives KOH, K2CO3, KC2H3O2 and KCl, for potassium contents in char up to about 5 wt%)
