Reactors - processdesign

Feb 22, 2016 · Fixed-bed Reactors. Indirect heat transfer is not often utilized to control the temperature in fixed-bed reactors, as it hard to maintain uniform temperature across the radial section of the catalyst bed. In cases where temperature control is required, the reactor will be split into smaller sections.
