A comprehensive kinetic simulation of different types of plant fibers: autocatalytic degradation mechanism
(2019-08-15)
Kinetic analysis of the non-isothermal degradation of three different plant fibers has been performed using isoconversional model-free methods, model-fitting methods in order to establish if different kinetic approaches ...
Non-isothermal kinetic applied to thermal decomposition of commercial alkyd varnish
(Springer, 2005-01-01)
Samples of commercial alkyd resin varnish were spread in a film form on slides, dried at room temperature and exposed to solar radiation from one day up to seven months.Thermogravimetric measurements have been done. Based ...
Kinetic parameters of red pepper waste as biomass to solid biofuel
(2016-03-01)
This work aimed to study the kinetic of thermal degradation of red pepper waste as solid biofuel to bioenergy production. The thermal degradation experiments were conducted at three heating rates, 5 °C/min, 7.5 °C/min and ...
A review of pharmacokinetic parameters of metabolites and prodrugs
(Drug Metabolism Letters, 2014)
In drug discovery and development, the kinetic study of active metabolites plays an important role, helping to define the time course of the drug in the body and its activity or toxicity. After a pharmacokinetics assessment ...
Kinetic studies of urban solid residues and leachate from sanitary landfill
(Springer, 2009-08-01)
Urban solid residues are constituted of food remaining, grass leaves, fruit peelings, paper, cardboard, rubber, plastic, etc. The organic fraction formed represents about 50% during the decomposition yields biogas and ...
Sublimation/volatilisation kinetics of 8-hydroxyquinolines and their nitro-derivatives
(Kluwer Academic Publ, 2001-01-01)
5-Nitro-8-hydroxyquinoline (B) and 5,7-dinitro-8-hydroxyquinoline (C) were obtained from nitration of 8-hydroxyquinoline (A) and purified in acetone medium and under heating in which the formation of (B) or (C) depends on ...
On the analysis of glow curves with the general order kinetics: Reliability of the computed trap parameters
(Elsevier Science, 2017-04)
Nowadays the most employed kinetics for analyzing glow curves is the general order kinetics (GO) proposed by C. E. May and J. A. Partridge. As shown in many articles this kinetics might yield wrong parameters characterizing ...
Thermal degradation of a composite solid propellant examined by DSC - Kinetic study
(Kluwer Academic Publ, 2004-01-01)
The thermal decomposition of ammonium perchlorate (AP)/hydroxyl-terminated-polybutadiene (HTPB), the AP/HTPB solid propellant, was studied at different heating rates in dynamic nitrogen atmosphere. The exothermic reaction ...
Determination of the intrinsic kinetic parameters of sulfide-oxidizing autotrophic denitrification in differential reactors containing immobilized biomass
(ELSEVIER SCI LTDOXFORD, 2012)
Nitrogen removal coupled with sulfide oxidation has potential for the treatment of effluents from anaerobic reactors because they contain sulfide, which can be used as an endogenous electron donor for denitrification. This ...
Non-isothermal kinetic for lyophilized leachate from sanitary landfill and composting usine
(Springer, 2007-12-01)
Leachate samples from a sanitary landfill of Araraquara city and composting usine of Vila Leopoldina, São Paulo, Brazil were lyophilized to remove the water content. TG/DTG curves at different heating rates were recorded. ...
