摘要

An experimental evaluation of a microchannel reactor was completed to assess the reactor performance for the catalytic decomposition of vaporised formic acid (FA) for H2 production. Initially, X-ray powder diffraction (XRD), elemental mapping using SEM-EDS and BET surface area measurements were done to characterise the commercial Au/Al2O3 catalyst. The reactor was evaluated using pure (99.99%) and diluted (50/50 vol.%) FA at reactor temperatures of 250–350°C and inlet vapour flow rates of 12–48 mL.min-1. Satisfactory reactor performance was demonstrated at 350°C as near- equilibrium FA conversion (>98%) was obtained for all flow rates investigated. The best operating -1 point was identified as 350°C and 48 mL.min (pure FA feed) with a H2 yield of 68.7%. At these conditions the reactor performed well in comparison to conventional systems, achieving a H2 -1 -1 production rate of 11.8 NL.gcat .h . This paper therefore highlights important considerations for ongoing design and development of microchannel reactors for the decomposition of FA for H2 production.
