Fixed bed vs packed bed reactors

Web6K views 3 years ago At high enough linear velocity, the smallest catalyst particles escape from the bed and have to be separated from exhaust gases and recycled. In fluidized bed, heat... 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. •
