This study investigates the role of structured catalyst geometry in intensifying FTS performance using FeMnK catalysts selectively tailored for aviation-range hydrocarbons. The catalyst was synthesized via organic combustion and further modified by microwave irradiation, with structural properties characterized by X-ray diffraction. Aluminum honeycomb monoliths with square, circular, and triangular channel geometries were designed and fabricated by 3D printing, followed by catalyst deposition through dip-coating. High-pressure FTS experiments conducted at 30 bar and 300 °C demonstrate that channel geometry significantly influences conversion and selectivity by affecting flow dynamics and reactant mixing. The results highlight the potential of geometry-optimized structured catalysts to enhance FTS efficiency and support advanced reactor designs for sustainable aviation fuel production.}, language = {en} } @misc{JafariAbadiMbuyaetal., author = {Jafari, Mitra and Abadi, Amirreza and Mbuya, Christel-Olivier Lenge and Dorneanu, Bogdan and Arellano-Garcia, Harvey}, title = {Fischer-Tropsch synthesis and hydrocracking process integration : a study on mesoporosity modification and acidity optimization}, series = {100 Years Fischer-Tropsch Process A Central Pillar of Future Energy Systems Conference}, journal = {100 Years Fischer-Tropsch Process A Central Pillar of Future Energy Systems Conference}, pages = {1 -- 3}, abstract = {Machine learning (ML) is employed to identify the key parameters influencing CO conversion and C5+ selectivity.

Specifically, the goal is to optimize the acidity of the zeolite by determining the ideal concentration of NH4+ during the ion-exchange step.}, language = {en} }
