Nitrogen carrier gas flow for reduced steam requirements of water splitting in a packed bed hydrolysis 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...

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...

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

Modeling of Fischer–tropsch Synthesis Packed Bed Reactor for Producing Liquid Fuels from Natural Gas

A tubular pilot scale fixed-bed reactor for the Fischer–Tropsch Synthesis (FTS) was simulated to numerically demonstrate the conversion of synthesis gas (CO+H2) to higher hydrocarbons over an iron based catalyst. The reactor was a 3.1 cm diameter and 2.75 m length steel tube. The feed temperature were between 563583 K. Saturated water was employed to control the peak temperature within the cata...
