Abstract
We demonstrated that organometallic catalysts can be immobilized in a gas-phase packed bed reactor (PBR) by coating inorganic particles with a non-volatile polymer-catalyst solution. We validated the methodology through a case study on the ethanol coupling reaction (Guerbet reaction) catalyzed by a ruthenium pincer complex and on the hydrogenation of hexene catalyzed by an iridium complex. Our implementation of this technique serves to inspire the adoption of advanced reactor engineering strategies for the study of homogeneous catalysts.

Notes
For batch reactions, the [EtOH] in PEG is 0.87 M. This value was calculated using initial substrate loadings. Under flow in our PBR and CSTR, the [EtOH] is ca. 0.25 M. This value Was determined by simulating the VLE for a PEG/EtOH mixture in CHEMCAD(SRK).
