Fixed bed vs packed bed reactors
WebIf it is controlled by mass transfer diffusion then you should go for batch wise process or other assembly like fluidised bed. But if it controlled by reaction kinetics then packed bed... WebPressure drop over a slurry reactor is much less, typically 0.1 MPa versus 0.4 MPa for a multi-tubular unit decreasing the gas compression cost. • Because of the lower catalyst loadings in slurry bed reactors the catalyst consumption per ton of product is four times lower than in fixed bed units. •
