A Review of Packed Bed Reactor and Gradient-less Recycle Reactor for Determination of Intrinsic Reaction Kinetics

Optimal synthesis of rotating packed bed reactor

Rotating packed bed (RPB), a novel apparatus involving process intensification (PI), has been successfully used in the chemical industry in recent decades. In this paper, we establish a connection between process integration and process intensification for which we propose a superstructure involving a RPB and a packed bed (PB) in order to determine the optimal integrated design. We describe mod...

Packed bed reactor for degradation of simulated cyanide-containing wastewater

The discharge of cyanide-containing effluents into the environment contaminates water bodies and soil. Effective methods of treatment which can detoxify cyanide are the need of the hour. The aim of the present study is to develop a bioreactor for complete degradation of cyanide using immobilized cells of Serratia marcescens RL2b. Alginate-entrapped cells of S. marcescens RL2b were used for comp...

Oxidation of Ethene in a Wall-cooled Packed- Bed Reactor

Abstract--The selective oxidation of ethene over a silver on cx-alumina catalyst was studied in a pilot plant with a wall-cooled tubular packed bed reactor. Gas and solid temperatures in the catalyst bed were measured at different axial and radial positions as well as concentrations at different axial position. Total pressure, inlet mole fraction ethene, mass flow rate and wall temperature were...

Control of a Fluidized Bed Polyethylene Reactor

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...
