The invention provides a system and a process for catalytic cracking of a carbon-based material by coupling a monolithic catalyst with microwaves. The system comprises a microwave multi-mode pretreatment reactor, an infrared temperature controller, a gas storage device, a gas supply device, a gas flow controller, a microwave resonant cavity, a quartz reaction device, an integral porous composite catalyst, a transverse single-mode microwave reactor, a waveguide, a material storage device and a condensing device. A mixture of a carbon-based material and activated carbon enters a microwave multi-mode pretreatment reactor for pretreatment, and obtained cracked gas enters a gas storage device for continuous feeding; the cracking gas enters a microwave resonant cavity and is in continuous contact with an integral porous composite catalyst in a microwave field in an inert atmosphere, and the cracking gas is catalytically converted into hydrogen-rich gas and waste residues; hydrogen-rich gas is cooled by the condensi
