TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The reforming catalyst is a noble metal catalyst or loaded nickel-based catalyst.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The pressure of the material biogas is 1.2 MPa. The tube-and-shell reactor comprises a reactor shell passage, an upper closure plate and a lower closure plate. The reactor shell passage is fixedly connected to the upper closure plate and the lower closure plate separately. The upper part of the reactor shell passage is connected to a smoke outlet and its middle part is connected to a secondary air inlet. One side on the lower part of the reactor shell passage is connected to a primary air inlet and its other side is connected to a tail gas inlet. A converting pipe is connected in the reactor shell passage and its two ends are respectively connected to a converter flange and a converted gas outlet. The upper part of the converting pipe is connected to a material gas inlet. A thermal insulating plug and a converting catalyst salver are arranged inside the converting pipe. The converter flange is connected to a flange cover. The reactor shell passage is equipped with a first gas distribution plate, a second gas distribution plate and a third gas distribution plate in turn inside. The membrane separator comprises a cavity, a gas inlet end and a tail gas outlet end. The cavity is equipped with a palladium membrane component inside. A hydrogen outlet pipe is installed on the cavity. The two ends of the cavity are respectively equipped with a first flange and a second flange. The air inlet end is connected to a gas inlet end, which is connected to a third flange fixedly connected to the first flange. A gas inlet end tube plate is arranged between the first flange and the third flange. The tail gas outlet end is connected to a gas outlet end, which is connected to a fourth flange fixedly connected to the second flange. A gas outlet end tube plate is arranged between the second flange and the fourth flange.
