Bio-multi-reactor hydrogen generation method and system

A bio-multi-reactor hydrogen generation method using a bio-multi-reactor hydrogen generation system including a plurality of carbonization-water gasification furnaces and a plurality of heating furnaces arranged alternately side by side, the method comprising:

• arranging biomass of different sizes or coal, which are solid combustibles, and a water gasification catalyst in each of the carbonization-water gasification furnaces;
• dry distilling the solid combustibles by heating from each of the heating furnaces adjacent to each of the carbonization-water gasification furnaces;
• gasifying carbon obtained by the dry distilling within each of the carbonization-water gasification furnaces into a water gas containing carbon monoxide by blowing steam through a top of each of the heating furnaces into the carbon to cause a water gasification reaction to take place;
• increasing reaction speed at which the water gas is generated by the water gasification catalyst;
• maintaining each of the heating furnaces at a temperature for dry distilling the solid combustibles in each of the carbonization-water gasification furnaces by collecting a combustible gas generated in the dry distilling of the solid combustibles in each of the carbonization-water gasification furnaces in a tank and supplying the combustible gas to each of the heating furnaces for combustion;
• and
• gasifying soot or tar having stuck to an inside of each of the carbonization-water gasification furnaces during the dry distilling of the solid combustibles by steam blown from steam blowing pipes in two or more upper and lower rows installed in each of the carbonization-water gasification furnaces.
