Critical review on enhanced production of methane in microchannel reactors as carbon dioxide utilization approach

Original language description

Methanation of carbon dioxide is a key strategy for capturing and utilising carbon in response to rising CO2 emissions. Unlike conventional reactors, microreactors offer significant process intensification through improved heat and mass transfer, greater control and suppression of side reactions, enabling cleaner and more efficient methane production. This review explores the rapidly evolving field of CO2 methanation in microreactor systems. A comprehensive evaluation of recent studies shows that scaled-up multichannel microreactors, often integrated into modular configurations, are predominantly used with Ni- or Ru-based catalysts under stoichiometric H2/CO2 ratios, at temperatures of 275-350 degrees C and at elevated pressures. Despite promising results, the transition from laboratory to industrial application remains limited, highlighting the urgent need for pilot-scale demonstrations and validated scale-up approaches. This work makes a novel contribution by delivering a detailed analysis of the factors that influence CO2 methanation performance in microreactors, addressing the key practical and engineering aspects that are relevant to real-world implementation, presenting the emerging trends and technological pathways for synthesising methane from CO2, and critically discussing the scale-up strategies and the techno-economic constraints that are specific to microchannel methanation systems.
