Ecotoxicological characterization of biochars: role of feedstock and pyrolysis temperature.
Seven contrasting feedstocks were subjected to slow pyrolysis at low (300 or 350°C) and high temperature (550 or 600°C), and both biochars and the corresponding feedstocks tested for short-term ecotoxicity using basal soil respiration and collembolan reproduction tests. After a 28-d incubation, soil basal respiration was not inhibited but stimulated by additions of feedstocks and biochars. Howe...
متن کاملThermogravimetric characterization of corn stover as gasification and pyrolysis feedstock
Interest in generating energy from biomass has grown tremendously in recent years. Corn stover is an agricultural by-product, which is abundant in quantity. Gasification and pyrolysis are efficient methods of harnessing energy efficiently from corn stover. The performances of mathematical models to predict the product gas quality rely on characterization of feed materials and the reaction kinet...
متن کاملPyrolysis and catalytic pyrolysis of protein- and lipid-rich feedstock
In this study, pyrolysis of microalgal remnants was investigated for recovery of energy and nutrients. Chlorella vulgaris (C.vulgaris) biomass was first solvent-extracted for lipid recovery then the remnants were used as the feedstock for fast pyrolysis experiments using a fluidized bed reactor at 500 o C. Yields of bio-oil, biochar and gas were 53, 31, and 10wt.%, respectively. Bio-oil from C....
متن کاملWine by-products: phenolic characterization and antioxidant activity evaluation of grapes and grape pomaces from six different French grape varieties.
Grenache, Syrah, Carignan Noir, Mourvèdre, Counoise and Alicante Bouchet grape seeds and skins, harvested in 2009 and 2010 in the Rhône valley area of France, and their respective pomaces remaining after vinification, were analyzed for their phenolic composition and antioxidant activity. The polyphenol content was quantified by HPLC and the Folin-Ciocalteu assay. The antioxidant potential was m...
متن کاملKinetic equations for thermal degradation of polymers
Kinetic equations are analyzed for thermal degradation of polymers. The governing relations are based on the fragmentation–annihilation concept. Explicit solutions to these equations are derived in two particular cases of interest. For arbitrary values of adjustable parameters, the evolution of the number-average and mass-average molecular weights of polymers is analyzed numerically. Good agree...
