Pyrolysis oils derived from lignocellulosic feedstocks by way of fast pyrolysis offer the possibility of a distinct alternative to the use of petroleum-based fuels. However, an inherent drawback associated with pyrolysis oil its high oxygen content which is due to the nature of the lignocellulosic...

The aim of the present study was to demonstrate the preparation and characterization of planar biomimetic bacterial water-channel protein Aquaporin Z (AQPZ)-incorporated polymer membranes on porous solid substrates by vesicle spreading for water treatment. AQPZ -incorporated polymer vesicles were...

Though manufacturing facilities always seem to be “fire-fighting,” there are times when the plant is actually running well. What is an engineer to do? Plant improvements and optimization opportunities are everywhere, but how does one go about identifying where they are and prioritizing their work...

Temperature distribution in activated carbon bed during adsorption of nitrogen (model gas for hydrogen); experiment & mathematical model Agnieszka Truszkowska 1 , Christopher Loeb 1 , Richard Chahine 2 , Bruce Hardy 3 and Goran N. Jovanovic 1 1 Oregon State University, Department of Chemical,...

A transient three-dimensional heat and mass transfer model is developed for a semi-transparent optically large, non-uniform and non-isothermal particle exposed to an external source of high-flux irradiation and undergoing chemical reaction. The model couples radiation, conduction and convection...

Incineration of wastes and combustion of chlorine-rich coal are the major sources of local and global environmental pollution related to hydrogen chloride (HCl) emission. At the same time, HCl is a common tail gas in chemical industry such as PVC and Freon production. HCl is regarded as the most...

Removal of heat from confined cabins and space habitats is of immense importance to NASA in order to ensure proper thermal control. The design of important thermal subsystems for future applications as in boilers, condensers, evaporators, heat exchangers etc will involve complicated fluid flow...
