The invention discloses a catalytic hydrogen production method and device suitable for a hydrogen energy automobile. The method disclosed by the invention specifically comprises the following steps: electromagnetically heating to dry a catalyst under nitrogen protection, stopping introduction of nitrogen and starting a liquid organic hydride cooler; starting a temperature control rheometer, maintaining the rotating speed of a rotary electromagnetic heating disc, and after the catalyst is stabilized at the reaction temperature, spraying, atomizing and feeding the liquid organic hydride intermittently; and condensing, separating and discharging the product hydrogen. According to the method and device disclosed by the invention, hydrogen production reaction conditions are uniformly designed and optimized to obtain the optimal reaction conditions. According to the method and device disclosed by the invention, a noble metal catalyst is replaced by cheap raney nickel, so that the reaction cost is lowered, and a carbon deposition deactivated catalyst can be regenerated by eliminating carbon with water vapor. A spraying and atomizing feeding method is adopted, the rotary electromagnetic heating is arranged, the surface temperature return time of the catalyst is fully utilized, and dehydrogenation reaction is carried out under a wet-dry multiphase reaction condition, so that the reaction efficiency is improved. No carrier gas is adopted, and the produced hydrogen is high in purity and free of being re-separated, so that the method and device are suitable for the hydrogen energy automobile.

The invention discloses a catalyst for methane preparation using biomass and coal and a preparation method and application of the catalyst and belongs to the field of catalyst preparation and application. The catalyst uses active coke as the carrier to load an active component which is nickel, cerium or yttrium and auxiliaries which are iron oxide and calcium oxide. The preparation method includes: mixing low-rank coal with binder and iron oxide powder to prepare active coke; impregnating for several times to load the active component and the calcium oxide. Methane can be generated by directlymixing the obtained catalyst with the biomass and coal and feeding water steam to perform reaction. The active coke is prepared from the low-rank coal, so that the carrier which is porous and large in specific surface area can be provided, and the preparation cost of the catalyst can be lowered; the catalyst can simultaneously catalyze biomass and coal pyrolytic reaction, water gas change reaction and methanation reaction.
