In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio

Chemie Ingenieur Technik, EarlyView.
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

Chemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

3D‐Printed Coil Immobilized Enzyme Reactors for Laccase Biocatalysis in Single‐ and Two‐Phase Flow

Chemie Ingenieur Technik, EarlyView.
Development of 3D‐printed immobilized enzyme reactors functionalized with laccase for continuous‐flow biocatalysis. Surface coupling and reactor design enhanced stability and mass transfer, enabling efficient and reusable biocatalytic processes.

Process Modeling for Propylene Polymerization to Transfer Reaction Kinetics From Lab to Plant

Chemie Ingenieur Technik, EarlyView.
The modeling approach combines an industrial model for a fourth‐generation Ziegler–Natta catalyst with lab‐scale derived kinetics of a novel fifth‐generation catalyst. By transferring intrinsic kinetics across scales, polypropylene production can be predicted. Accurate melt flow rate prediction is only obtained with an additional adjustment.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.
