The invention discloses a
hydrogen production
system by utilizing
thermochemical reaction thermally driven by
solar energy under medium-lower temperature, which comprises a material supplying device for storing materials required for producing
hydrogen, a material mixing device for mixing raw materials and non-reactants, a material measuring device for controlling the volume of raw materials sent into a preheater per unit time, the preheater for preheating raw materials, a
solar energy absorption reactor for driving
raw material to carry out reforming reaction by utilizing absorbed
solar energy heat, a solar energy collector for aggregating solar energy with low energy flow density into medium-lower temperature
heat energy with
high energy flow density in a form of line focus so as to provide heat for material reforming reaction, a condenser for cooling reaction products, a gas-liquid separator for separating gas and liquid of a mixture, and a PSA (
pressure swing adsorption)device for separating the obtained pure
hydrogen. The invention also discloses a method for producing hydrogen by utilizing
thermochemical reaction thermally driven by solar energy under medium-lower temperature. The
system and the method of the invention reduce the cost of producing hydrogen by utilizing solar energy and are beneficial to
mass popularization and application.
