The invention discloses a coalbed methane deoxidizing and hydrogen-manufacturing device and technology. The coalbed methane deoxidizing and hydrogen-manufacturing device comprises a water steam generator, a gasifying and deoxidizing reactor, a reduction reactor, a hydrogen generator and an oxidizing reactor. The technology comprises the following steps of firstly, vaporizing the vaporizing raw material in a vaporizing section, enabling the reaction gas after vaporizing to react with oxygen in the coalbed methane under the action of a deoxidizing catalyst, and separating the coalbed methane after deoxidizing into natural gas, CO (carbon monoxide) and other gases; sending the obtained CO into the reduction reactor, generating reduction reaction with metal oxide with high valence state, sending the metal or metal oxide with low valence state after reduction into the hydrogen reactor, and reacting with led water steam to obtain clean raw material of H2 (hydrogen); sending the metal oxide with secondary high valen
