This folder contains the supporting data and files prepared for a Zenodo deposit related to the paper **Oscillatory motion of trickle-bed reactor can break up liquid channeling and thus increase reaction efficiency**. Abstract:We report the observation that applying an oscillatory pitching motion can substantially increase the reaction efficiency in a trickle-bed reactor used for the hydrogenation of liquid organic hydrogen carriers (LOHC). In the present experiments, steady-state reaction was reached 14 times faster and with approx. 25% larger mean efficiency for the pitching reactor compared to the conventional stationary reactor. Increasing the pitching amplitude from 1◦ to 4◦ accelerated the reaction by about 45%. Strong memory effects were observed, with increased reaction efficiency being maintained for 2 hours in a non-moving reactor, if the reactor had been operated under oscillatory pitching motion beforehand. Therefore, the present results indicate that substantial efficiency increases do not require continuous oscillations, instead already occasional reactor motions may suffice. We hypothesize that the increase in efficiency is due to breaking-up of liquid channels. Computational Fluid Dynamics (CFD) simulations and cold-flow experiments are reported that strongly support this theory.
