WABT - weighted average bed temperature

WABT - Weighted Average Bed Temperature is a way to get one representative temperature from an adiabatic reactor (no heat loss or gain to the surroundings), which in reality have an increasing or decreasing temperature profile from inlet to outlet. The temperature profile occurs due to exothermic or endothermic reactions taking place in the reactor. The WABT is used to indicate the catalyst .

Acknowledgments Adapted for the internet from "The Fluid Bed Reactor," produced by the National Historic Chemical Landmarks program of the American Chemical Society in 1998.

Catalytic Fixed-Bed Reactors

2. Fixed-Bed Reactors for Liquid-Phase Reactions Usually fixed-bed reactors are either operated with gas-phase reactions or in a trickle-bed mode, whereby a liquid reactant trickles through the bed from top to bottom, while a gaseousreactant flowsupward.Here,fixed-bed reactors with reactants in the liquid phase will be considered.

Elements of Chemical Reaction Engineering

Trickle Bed Reactor The material presented in this example is meant to serve as an introduction to trickle bed reactors. Other worked-out trickle bed example problems can be found in an article by Ramachandran and Chaudhari 6. In addition, the hyrodesulfurication of a hydrocarbon in a trickle bed reactor is given in detail by Tarhan 7.

AVR reactor - Wikipedia

The AVR reactor (German: Arbeitsgemeinschaft Versuchsreaktor) was a prototype pebble bed reactor, located immediately adjacent to Jülich Research Centre in West Germany, constructed in 1960, grid connected in 1967 and shut down in 1988.It was a 15MWe, 46 MWt test reactor used to develop and test a variety of fuels and machinery.

CIRCULATING FLUIDIZED BED REACTOR – Chemical Engineering .

Jun 09, 2019 · A circulating fluidized-bed (CFB) reactor is extremely the same as a bubbling fluidized-bed reactor. the main distinction is that the gas rate.If the gas rate of a bubbling fluidized bed will increase, at some Location the force exerted on the particle are enough to move it upwards, carrying it outside of the bed. this case is named elutriation. In a CFB, elutriation carries each sand and char .

Reactors - processdesign

Fixed Bed Reactors; In a fixed-bed reactor, the reagent flows over a stationary bed of packed catalyst (Towler and Sinnott, 2013). This is the most common type of reactor used for heterogeneous catalysis as long as the catalyst does not require continuous regeneration and the reaction mixture does not require high agitation (Towler, 2012).
