Analytical pyrolysis As a method to characterize tannery wastes / Antonio Marcilla in Industrial & engineering chemistry research, Vol. 50 N° 15 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 15 (Août 2011) . - pp. 8994–9002 Titre : Analytical pyrolysis As a method to characterize tannery wastes Type de document : texte imprimé Auteurs : Antonio Marcilla, Auteur ; Angela Nuria Garcia, Auteur ; Milagros Leon, Auteur Année de publication : 2011 Article en page(s) : pp. 8994–9002 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Leather  industry  Tannery  Pyrolysis Résumé : The main objective of this paper is to study the thermal decomposition of waste products from leathers tanned with different tanning agents, from two different points of view: (i) thermogavimetric analysis and (ii) flash pyrolysis using a Pyroprobe device connected to a gas chromatograph with a mass spectrometer (Py/GC-MS). Both techniques allow us to characterize the samples by evaluating their potential differences regarding the decomposition process as well as by identifying the significant volatile compounds obtained depending on the tanning processes. The results have been treated using a multrvariate statistical analysis method.

A new dubinin−radushkevich-modified BET combined equation to correlate with a single procedure the full relative pressure range of 77 K N2 isotherms of solids with different textural properties / Antonio Marcilla in Industrial & engineering chemistry research, Vol. 48 N° 24 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 10820–10826 Titre : A new dubinin−radushkevich-modified BET combined equation to correlate with a single procedure the full relative pressure range of 77 K N2 isotherms of solids with different textural properties Type de document : texte imprimé Auteurs : Antonio Marcilla, Auteur ; Amparo Gómez-Siurana, Auteur ; Francisco J. Valdés, Auteur Année de publication : 2010 Article en page(s) : pp. 10820–10826 Note générale : Industial chemistry Langues : Anglais (eng) Mots-clés : A  New  Dubinin−Radushkevich-Modified--BET--Combined--Equation--Correlate--Single  Procedure--Full  Relative--Pressure--Range--77  K  N2  Isotherms--Solids--Different--Textural--Properties Résumé : In this work, a model capable of adequately correlating and reproducing experimental adsorption isotherm data in the overall relative pressure range is suggested. The equation includes a Dubinin−Radushkevich term and a modified BET term that avoids the discontinuity of BET equation at high relative pressures. Thus, the typical independent application of the Dubinin−Radushkevich and BET equations, involving the need of a selection of the respective relative pressure range, is substituted by a single optimization procedure, permitting the calculation of the values of the parameters characterizing the textural properties of solids. The validity of the procedure has been checked through its application to several experimental examples, corresponding to types I, II, and IV isotherms, showing excellent results in all of the cases.
