The kinetics of the steam-assisted gasification for three different agro-industrial solid wastes (sawdust, olive and plum pits) was studied by macro thermo-gravimetric analysis (macro-TGA) at different heating rates (5, ...

The air/steam gasification of wood sawdust (SD), plum and olive pits (PP, OP) bio-wastes was studied using macro-thermogravimetric analysis at three heating rates (5, 10, 15K/min). Three stages were identified during ...

La demanda energética se ha convertido gradualmente en un factor crítico para el sector industrial internacional. Por esta razón se han desarrollado y promovido las tecnologías basadas en fuentes de energía renovables, ...

A macro-thermogravimetric analysis (macro-TGA) was applied to analyse the non-isothermal drying of different bio-wastes (quince solid waste, grape marc and pumpkin shell from different enterprises located in San Juan ...

La práctica académica fue realizada en la empresa Carbones del Cerrejón Limited, la cual es una de las grandes empresas pertenecientes al sector primario de Colombia cuyo fin va dedicado a la exploración, extracción, ...

Composites are considered a class of synergic material by using two or more different constituents in order to obtain a final product in which properties are impossible to obtain using only one of the components. The choice ...

For an increase in grain yield, it is necessary to use nitrogen fertilizers, currently urea is the main fertilizer used because of its nitrogen content, however some obstacles must be overcome. Urea, when applied to the ...

Alginate microparticles were prepared by spray drying technique and chemically cross-linked with epichlorohydrin. Microparticles were characterized by size, surface morphology (SEM), zeta potential, thermal analysis (TGA/DSC) ...

Bacterial cellulose (BC) has established to be a remarkably versatile biomaterial and can be used in wide variety of applied scientific endeavors, especially for medical devices. In fact, biomedical devices recently have ...
