BACKGROUND 2,6-dimethylphenol (2,6-DMP) is a product of phenol methylation, especially important for the plastics industry. The process of phenol methylation in the gas phase is strongly exothermic. In order to ensure good temperature equalization in the catalyst bed, the process was carried out using a catalyst in the form of a fluidized bed - in particular, the commercial iron-chromium cataly...

Recent experiments have investigated the response of smooth muscle cells to transient stretch-compress (SC) and compress-stretch (CS) maneuvers. The results indicate that the transient SC maneuver causes a sudden fluidization of the cell while the CS maneuver does not. To understand this asymmetric behavior, we have built a biomechanical model to probe the response of stress fibers to the two m...

Film coating of fine particles (5-20 microns) by polymers has a wide range of industrial applications, yet few techniques are commercially available that are environmentally friendly. In this study, four different techniques are considered with an ultimate goal of developing a reliable technique that is scaleable and is also environmentally friendly. Two of these techniques are fluidization bas...

ISSN 2277 5056 | © 2012 Bonfring Abstract--Fluidization is an operation in which solid particles are kept under suspension supported by the upward flow of liquid/gas phase. In classic fluidization the solids density are higher than the liquid, where as in Inverse fluidization the solids density are lower than that of continuous liquid phase. The phase holdup measurements in three phase classic/...

Liquid fluidization of mixtures solid particles spherical and cylindrical shape has been numerically simulated. The simulations explicitly resolve the solid–liquid interfaces by means an immersed boundary method implemented in a lattice-Boltzmann flow solver. A soft collision algorithm deals with particle–particle contacts close-range hydrodynamic interaction. systems studied have overall solid...

The physical parameters of two products widely used in the confectionery industry – peanuts and cocoa beans have been studied. hydrodynamic characteristics these products, influencing fluidized bed roasting regime, determined. hydrodynamics a rotating-pulsed fluidization cited materials has examined. Dependences are derived for calculating pressure drops initial velocity particles during creati...

Composite zeolites impregnated with anhydrous salt particles are promising materials for use in domestic thermochemical energy storage (TCES), however they have limited power output. Fluidization has the potential to increase mass and heat transfer of TCES systems. In this study, a composite material LiX zeolite MgCl2 is produced. This batch then fluidized at different gas velocities study whet...

This paper aims to study the biosorption for removal of lead, cadmium, copper and arsenic ions using algae as a biosorbent. A series experiments were carried out obtain breakthrough data in fluidized bed reactor. The minimum fluidization velocities beds found be 2.27 3.64 mm/s mish sizes 0.4-0.6 0.6-1 mm diameters, respectively. An ideal plug flow model has been adopted characterize solved nume...
