Synthesis of Silver Sulfide Quantum Dots Via the Liquid–Liquid Interface Reaction in a Rotating Packed Bed Reactor

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...

Citronellyl Butyrate Synthesis in Non-Conventional Media Using Packed-Bed Immobilized Candida Rugosa Lipase Reactor

The synthesis of citronellyl butyrate by direct esterification reaction catalyzed by immobilized lipase from Candida rugosa was studied in a continuous packed bed reactor using n-hexane as organic solvent. Parameters such as residence time, temperature, and pH were examined. The optimum conversion was obtained at a flow rate of 1 ml/min (residence time 8 min), temperature of 50 °C, and pH 7.5. ...

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...

Catalytic Combustion of Biogas-Hydrogen Mixtures in a Packed Bed Reactor

Effect of Pulsing on Reaction Outcome in a Gas-Liquid Catalytic Packed-Bed Reactor

There has been continuous interest and fascination with the fluid dynamics of trickle-beds (i.e., cocurrent gas-liquid packed-bed reactors) at least since Weekman and Myers (1964) first proposed a regime map for their operation. Consistent with other flow regime maps before (Baker, 1954; for gas-liquid pipe flow) and since (e.g., Mandhane et al., 1974; for pipe flow), visual observations were u...
