Kinetic modeling of solid-gas reactions at reactor scale: A general approach [PDF]
International audienceA rigorous simulation of industrial reactors in the case of solid-gas reacting systems is a complicated task due to several difficulties linked to the kinetic problem at the scale of the solid grains and to the problem of gas and ...

The evaluation of geopolymer properties prepared by alkali activation of black coal ashes with high content of loss on ignition [PDF]
The utilization of fly ashes in Slovakia is lower than in other countries and dumping of fly ashes prevails. The dumping changeschemical and phase composition of fly ashes and so it decreases possibilities for their utilization. Fly ashes are mainly used

Phase transformations in xerogels of mullite composition [PDF]
Monophasic and diphasic xerogels have been prepared as precursors for mullite (3Al2O3-2SiO2). Monophasic xerogel was synthesized from tetraethyl orthosilicate and aluminum nitrate nanohydrate and the diphasic xerogel from colloidal suspension of silica ...

Effect of crystallization time on the hydrothermal synthesis of zeolites from kaolin and bauxite [PDF]
Kaolin and bauxite were used as alumina and silica sources to synthesize zeolites hydrothermally. The source mate-rials as well as the synthesized zeolites were characterized by X-ray diffraction (XRD) scanning electron microscopy (SEM), en-ergy ...
