Ammonia cracking hollow fibre converter for on-board hydrogen production

This work studies the feasibility of a pioneer technology for on-board hydrogen production: Ammonia Cracking Hollow Fibre Converter. The catalytic activity series ruthenium-based catalysts supported on carbon xerogel, during ammonia cracking reaction, was studied in packed bed reactor. To improve their physical-chemical properties, xerogels were activated either dioxide or atmosphere. most active catalyst (i.e. Ru-NCX) then deposited inside micro-structured hollow fibre support by combination sol-gel and incipient wetness impregnation methods. At 450 °C 1 atm reactor 4.6 times more efficient than rNH3 = 6.5 × 104 molNH3/m3·h·gcat 3.0 105 molNH3/m3·h·gcat, respectively), due to its narrower residence time distribution reduced mass transfer limitations. Furthermore, use converter entailed significantly lower pressure drop >99% less), volume 80% less) loading compared Therefore, potential this new is enormous, as it will push incorporation green present-day fuel scenario.
