Optimization of the drying operation requires a model containing the operating variables for fluid bed dryers (FBD). Modeling of FBD is still uncertain since the drying process is unpredictable and relies on empirical ...

Intracellular adenosine-5’-triphosphate (ATP) levels were measured in a metabolically engineered Zymomonas mobilis strain 8b over the course of batch fermentations of glucose and xylose mixtures. Recombinant Z. mobilis, a ...

Hydrodynamic characteristics (gas holdup, friction factor, and mixing in the liquid phase) in a bubble column with a non-Newtonian liquid phase (aqueous solutions of carboxymethylcellulose, or CMC, at different concentrations) ...

During the last few years concerns with distribution, supply and cost of conventional liquid fuels increased considerably. Several developed countries are seriously considering using hydrogen (no fossil combustible) as an ...

Wet granulation is one of the most important operations where fine particles are agglomerated into larger granules by adding a binder. The process is used in many chemical industries including pharmaceutical, mineral ...

Carbon dioxide is one of the most commonly used supercritical fluids. However, its uses are limited due to its low solubility capacity for polar substances. Addition of cosolvents improves the solubility of polar and ...

Currently, supercritical-fluid technology in the pharmaceutical and microelectronics industries is increasingly applied to solve difficult processing problems. The solubility of a solute in the supercritical fluid is the ...
