Process intensification in multifunctional reactors: A review of multi-functionality by catalytic structures, internals, operating modes, and unit integrations

Applied research on methane steam reforming properties of porous structural catalyst fabricated by selective laser melting technology

“…Therefore, the optimal design of the reactor structure is imperative for ensuring the sustained stability and performance of the entire catalytic system. The high packing density of the traditional granular catalyst can easily lead to excessive pressure drop in the reactor and poor heat and mass transfer performance of the fluid during the reaction, thus affecting the activity of the catalyst [25][26][27][28][29][30]. In recent years, the extensive utilization of static mixers in industrial mixing, heat transfer, and reaction units has presented a novel thinking for exploring structural catalysts in methane steam reforming [31,32].…”

Performance, Efficiency, and Flexibility Analysis of a High-Temperature Proton Exchange Membrane Fuel Cell-Based Micro-Combined Heat-and-Power System with Intensification of the Steam Methane Reforming Step by Using a Millistructured Reactor

“…A critical unit in micro-CHP systems is the reforming step. The industrial-scale operation of energy-intensive reactions, such as endothermic steam methane reforming (SMR), is challenging due to ineffective heat transfer from the external burners to the packed catalyst beds . It is obvious that thermal integration of the process is an important strategy to improve the overall energy efficiency of the system.…”

Can process intensification change the future of biodiesel?

“…With a simple and robust design, the monolithic reactor is considered a potential PI replacement for the conventional packed bed reactor in catalytic gas-solid reactions [115]. The monolithic catalyst is a construction of multiple narrow straight parallel channels manufactured from ceramics or metallic components which create an ease passage for the reactant flow [116]. This design reduces the pressure drop and increases the specific surface area of the reactor, thus, improving the conversion rate per unit volume and heat and mass transfer efficiency [116].…”
