Hydrogen energy is the clean and green secondary energy and energy carrier. Using solar energy driven methanol steam reforming to produce hydrogen can realize high efficiency hydrogen production and solar energy storage. Based on the advantages of high heat and mass transfer efficiency of fluidized bed

a concentrated solar energy fluidized bed methanol reforming system for hydrogen production is designed. The light pathway of heliostats field and the irradiation energy flow distribution on reactor surface are simulated

and the influence law of different operating parameters on the reforming reaction is explored. The results show that

compared with fixed bed

using fluidized bed reactor is more beneficial to improve the efficiency of hydrogen production by methanol steam reforming. When the irradiation intensity is 10 000 W/m2

the mole ratio of water to methanol is 1.4

the inlet flow rate is 0.40 m/s and the bed thickness is 0.20 m

the methanol conversion rate can reach 99.6% and the hydrogen yield can reach 2.57 mol/mol. The present investigations provide reference significance for reactor design and operation parameter optimization of solar methanol reforming hydrogen production.
