Gas-solid conversion in fluidised bed reactors [PDF]
, 2008 Asimplified model for gas–solid reactions in fluidised bed (FB) is proposed. Such models already exist for catalytic gas–solid reactions (CGSRs), providing general description of the system in terms of main governing parameters.

AIChE Journal, EarlyView.Abstract Magnetic field‐assisted concentration swing adsorption (CSA) provides an electrification‐compatible alternative to conventional temperature swing adsorption (TSA) by enabling rapid heating/cooling and energy‐efficient regeneration under near‐isothermal conditions, thereby eliminating the need for sensible heat input.

Coherent structures and bubble-particle velocity in 2-D fluidized beds [PDF]
, 2008 This work presents an experimental study to characterize ascending bubbles and granular velocity in the dense phase of a 2-D fluidized bed. Three different non-intrusive techniques based on images obtained with a high speed camera are developed, and ...

Mixing dynamics in bubbling fluidized beds [PDF]
, 2018 Solids mixing affects thermal and concentration gradients in fluidized bed reactors and is, therefore, critical to their performance. Despite substantial effort over the past decades, understanding of solids mixing continues to be lacking because of ...

Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma
Advanced Intelligent Systems, EarlyView.A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Towards accurate three-dimensional simulation of dense multi-phase flows using cylindrical coordinates [PDF]
, 2014 Most industrial scale fluidized-bed reactors are cylindrical, and the cylindrical coordinate system is a natural choice for their CFD simulation. There are, however, subtle complexities associated with this choice when using the Two-Fluid Model.

Confined fluidised bed porosity in the light of bubbling-bed models [PDF]
Chemical and Process Engineering, 2012 Abstract Based on hydrodynamic data, Kato-Wen and Kunii-Levenspiel bubbling-bed model parameters, supplemented with assumptions characteristic for tested confined fluidised bed, were analysed. The calculated bubble diameters and the bed composition proved essential influence of inter-particle space of packed compacted component onto fluidisation ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT In this study, the possibility of using aquafaba powder, derived from chickpea cooking water, as a natural emulsifier in the formulation of plant‐based coffee whitener was evaluated. For this purpose, coffee whiteners, which are emulsion type products, are obtained by high‐shear mixing followed by high‐pressure homogenization of the aqueous ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...
