Biomass gasification streams typically contain a mixture of CO, H2, CH4, and CO2 as the majority components and frequently require conditioning for downstream processes. Herein, we investigate the catalytic upgrading of surrogate biomass gasifiers through the generation of syngas. Seeking a bifunctional system capable of converting CO2 and CH4...

This work presents an overview of issues for the modeling of laminar flows in monolith catalysts. Both 0-D and 3-D models are evaluated for a parallel channel structured honeycomb catalyst (PC-HC), and a gyroid 3-D printed structured catalyst (G-3D). At the 0-D homogeneous reactor modeling level, the analysis is focused on the effect of the...

Among challenges implicit in the transition to the post–fossil fuel energetic model, the finite amount of resources available for the technological implementation of CO2 revalorizing processes arises as a central issue. The development of fully renewable catalytic systems with easier metal recovery strategies would promote the viability and...

This work presents a comparative study toward the development of efficient microreactors based on three-dimensional (3D)-printed structures. Thus, the study evaluates the influence of the metal substrate geometry on the performance of structured catalysts for the CO2 methanation reaction. For this purpose, the 0.5%Ru–15%Ni/MgAl2O4 catalyst is...
