TL;DR: In this paper, a combined mesoscale-microscale predictive approach was developed to apprehend the aerodynamic macroscale phenomena in structured packing-containing columns, including the elbow loss and jet splitting at the packed bed entrance, elbow loss at the column wall, the elbow losses at the jump from one layer to another, and the collisional losses at crisscrossing junctions.

TL;DR: In this paper, the transient kinetics of NiO carriers in the temperature range of 600 to 900°C in both a fixed bed microreactor and a fluid bed reactor were investigated.

TL;DR: In this paper, a double-slit model was developed to predict the frictional two-phase pressure drop, external liquid holdup, pellet-scale external wetting efficiency, and gas-liquid interfacial area in cocurrent downflow trickle-bed reactors operated under partially wetted conditions in the trickle flow regime.

TL;DR: In this paper, the potential and limits of in situ removal of water under DME synthesis conditions in a fixed-bed membrane reactor were studied numerically, and the motivation for in situ H2O removal was to displace the water−gas shift equilibrium to enhance conversion of CO2 into methanol to improve DME productivity.

TL;DR: In this paper, state-of-the-art correlations for shear and velocity slip factors and Ergun single-phase flow bed constants (Blake−Kozeny−Carman and Burke−Plummer bed parameters) were developed.
