Hydrogen Production via Microchannel Steam Reforming Using Metal-Organic Framework (MOF) Integrated Catalysts for Enhanced Thermal Management and CO2 Capture Integration

Project Abstract

Hydrogen production through microchannel steam reforming is investigated with an emphasis on MOF-integrated catalysts designed to significantly enhance thermal management and enable CO2 capture integration within compact reforming modules. The study develops a multiscale modeling framework that couples microchannel heat transfer, heterogeneous reaction kinetics, and MOF-enabled catalytic activity to optimize reforming performance under industrially relevant space–time constraints. A synthesized MOF catalyst with high intrinsic surface area and tunable metal nodes is embedded within a structured catalyst monolith to promote selective steam reforming while suppressing carbon formation at elevated temperatures. The research examines the synergistic effects of MOF confinement, pore architecture, and metal dispersion on catalytic activity, stability, and resistance to sintering, particularly under oscillatory heat flux typical of integrated heat exchangers. Thermal management is addressed through advanced heat transfer analyses, including conjugate heat transfer and phase-change considerations for feed preheating and product cooling, to minimize hotspot development and achieve uniform temperature profiles across microchannels. The work also integrates CO2 capture strategies by incorporating amine-functionalized MOF components and assessing their CO2 adsorption-desorption behavior in the reforming stream, aiming to facilitate on-site CO2 separation without compromising reforming efficiency. Reaction engineering aspects include kinetic parameterization for light-off behavior, steam-to-carbon ratios, and reforming versus methane reforming pathways as a function of catalyst loading, MOF conductivity, and channel geometry. A comprehensive techno-economic analysis evaluates capital expenditure, operating costs, and energy efficiency gains achievable through microchannel design and MOF-enhanced catalysis, comparing against conventional packed-bed reformers. Life cycle assessment estimates environmental impacts emphasizing CO2 avoidance potential and energy intensity reductions realized by integrating heat management and capture within a single compact unit. The experimental program, supported by in-situ spectroscopy and microscopy, characterizes catalyst evolution, selectivity to syngas (H2/CO), and carbon deposition tendencies under dynamic operating conditions. Sensitivity analyses identify critical design variables, including MOF thermal conductivity, pore connectivity, and channel aspect ratio, that most influence overall hydrogen yield, purity, and process resilience. The anticipated outcome is a scalable, thermally uniform microchannel reformer with MOF-integrated catalysts capable of delivering high hydrogen productivity, reduced CO2 emissions, and streamlined integration with downstream CO2 capture systems, while maintaining operational simplicity and robust long-term performance. This work contributes to the advancement of compact, efficient, and environment-friendly hydrogen production technologies suitable for decentralized energy systems and synthetic fuel applications.
