Abstract： To optimize catalyst geometric structures in packed beds and enhance hydrogen production eficiency，the effects of triple-periodic minimal surface （TPMS） structured catalysts on methane steam reforming reactions is investigated. The solid particle method is employed for numerical simulations comparing the flow，heat transfer，and reaction performance among TPMS-structured catalyst particles，conventional through-hole catalyst particles，and spherical catalyst particles. By analyzing reactive catalyst particles and incorporating classical thermal resistance theory，a novel thermal resistance evaluation method is developed to evaluate hydrogen production performance from the perspective of heat transfer and conversion. Results demonstrate that： The proposed thermal resistance evaluation method effectively reflects hydrogen production performance characteristics; the TPMS-structured spherical catalysts reduce flow energy loss by 22.97% compared to conventional spherical structures；in terms of heat transfer performance，they achieve the highest outlet temperature， showing a 4.48K increase over conventional spherical structures while reducing convective heat transfer resistance by 28.68% ； regarding reaction performance，they exhibit the maximum hydrogen production rate，which is 49.93% higher than that of conventional spherical structures， along with a 27.45% reduction in chemical reaction thermal resistance；overall，they achieve （204号 28.03% reduction in total thermal resistance. These findings demonstrate the superior efficiency of TPMS structures in methane steam reforming and provide a novel analytical approach for performance evaluation in packed beds.
