| description | The invention provides a method and a device for catalytic preparation of hydrogen from naphthenic hydrocarbon. The method comprises the following steps of: fixing a catalyst at the bottom of a reactor after the catalyst is washed by absolute ethyl alcohol; vacuumizing the reactor and introducing nitrogen into the reactor; heating the bottom of the reactor under nitrogen protection to ensure that the temperature of the catalyst slowly rises; stopping introducing the nitrogen after the catalyst is dried to open an organic liquid condenser; setting a dehydrogenation reaction temperature; heating the bottom of the reactor to be the dehydrogenation reaction temperature; injecting and feeding the naphthenic hydrocarbon at a constant velocity; discharging the generated hydrogen from the system after condensation and separation; and condensing the other steam components in a condenser and gathering the components into a product storage tank. By the method and the device, a precious metal catalyst is replaced by chea |
