An unsteady state analysis of packed bed reactors for gas-solid reactions.

Evaluation of Strategies for Temperature and Moisture Control in Solid State Packed Bed Bioreactors

Different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. The experiments were carried out within a 1-L solid-state packed bed bioreactor in which Aspergillus niger was cultivated on wheat bran....

Electron-transfer-initiated benzoin- and Stetter-like reactions in packed-bed reactors for process intensification

A convenient heterogeneous continuous-flow procedure for the polarity reversal of aromatic α-diketones is presented. Propaedeutic batch experiments have been initially performed to select the optimal supported base capable to initiate the two electron-transfer process from the carbamoyl anion of the N,N-dimethylformamide (DMF) solvent to the α-diketone and generate the corresponding enediolate ...

Imaging of hydrocarbon reactions in zeolite packed-bed reactors using positron emission profiling
