Temperature Swing Adsorption (TSA) processes are applied for the removal of impurities from various gas streams. The limiting factor of a TSA process is the regeneration step, which is characterized by long heating and cooling times. To reduce the regeneration time, indirectly heated and ... En savoir plus
Low Density Steels (LDS) mostly have additions of aluminum and/or manganese to reduce their weight and to obtain steel grades with various microstructures. The automotive industry is keenly interested in the development of LDS for reducing CO2 emissions by increasing fuel efficiency, ... En savoir plus
Microwave heating has been used in industry because of its pollution free and rapid heating technique [1]. It consists of an electromagnetic wave that passes through a media with a frequency between 300 MHz and 300 GHz [2] to generate heat in the system. The purpose of the current work ... En savoir plus
Microreactors have gained popularity in fuel production industry. This is due to its high surface area to volume ratio, enhanced mass and heat transfer, short residence time and a more sustainable practice. The catalytic hydrodeoxygenation (HDO) reaction of 4-Propylguaiacol (4PG) to 4 ... En savoir plus
Many industrial applications require special treatments for fluid products, such as: deagglomeration, dispersion, homogenization, emulsion, special mixing or even catalysis of chemical reactions. Such effects can be obtained through cavitation in a closed ultrasonic reactor, in which it ... En savoir plus
For civil engineering structures the interaction between concrete, its reinforcing steel bars and various environmental agents like humidity, CO2, O2 , and chloride is extremely important. Generally, the concrete provides appropriate conditions to prevent steel reinforcement bars from ... En savoir plus
Using the software COMSOL Multiphysics® based on the finite element method, a one-dimensionnal model has been developed to predict the transient behavior of a gaseous hydrogen flow through a porous bed. The problem is solved at a macroscopic scale, therefore, the porous bed is seen as a ... En savoir plus
Biodegradable scaffolds are often inserted in the body, to provide mechanical support to recovering broken or damaged tissues. Monitoring the degradation chemistry and mechanical response of these scaffolds is important: their degradation rate should match tissue regeneration rate, while ... En savoir plus
Granular and powdered activated carbons have been widely used for purification/filtration in air and water as catalysts or organic adsorbents. To obtain mechanical filtration capacity and inorganic reduction performance, activated carbon can be formed as a block-shaped porous media, ... En savoir plus
The DOE BETO consortium "ChemCatBio" has developed a packed bed catalyst for use in a Catalytic Fast Pyrolysis (CFP) process for producing biofuels and chemicals from lignocellulosic biomass. Another BETO consortium known as "CCPC" (Consortium for Computational Physics and Chemistry) is ... En savoir plus
