The invention discloses a reaction system and method for preparing a gas fuel by catalytic pyrolysis of organic solid waste. According to the method, collected organic solid waste is placed in a two-stage drying chamber for drying and then fed into a pyrolysis furnace, and pyrolytic carbon produced by the reaction is fed into a pulverizer and sprayed into a combustion chamber for combustion; the flue gas generated by the combustion of the combustion chamber heats the pyrolysis furnace and a catalytic cracking chamber; heated flue gas is introduced into a secondary drying chamber flue gas inletto dry a material; oil water vapor generated in the pyrolysis furnace enters the catalytic cracking chamber for secondary cracking refining; a catalyst is selected from a two-dimensional column-supporting molecular sieve, oil-water mixed vapor after catalytic cracking is introduced into a condenser, non-condensable gas coming out from the condenser is sequentially purified by a dust removing device and a CO2 absorption t
