The present invention discloses a device and method for generating high-purity hydrogen by biomass pyrolysis-chemical looping combustion. The device comprises a biomass pyrolysis unit, a chemical looping hydrogen generation unit and a waste heat recovery unit; the biomass pyrolysis unit comprises a vertical bin, a screw feeder, a rotary kiln pyrolysis reactor and a high temperature filter; the chemical looping hydrogen generation unit comprises a path switching system of intake gas end, at least one packed bed reactor and a path switching system of tail gas end, wherein the packed bed reactor is composed of three parallel packed bed reactors I, II and III, which are continuously subjected to fuel reduction-steam oxidation-air combustion stages (steam purging stage) successively; the waste heat recovery unit comprises a waste heat boiler, a cooler and a gas-liquid separator. According to the present invention, a process flow of generating hydrogen from biomass is short, high-purity hydrogen can be obtained by simple condensation and water removal of a hydrogen-containing product that is generated after entrance of a pyrolysis gas into the chemical looping hydrogen generation unit, no complex gas purification device is employed, and the costs for hydrogen generation are low.

A burner combustion chamber (3), a burner (7) for performing a burner combustion in the burner combustion chamber (3) a reformer catalyst (4) to which burner combustion gas is fed, and a heat exchange part (13a) for heating the air fed to the burner (7) are provided. A switching device (16, 17) able to switch an air flow route for introducing the outside air to the burner (7) between a high temperature air flow route (13) for introducing the outside air flowing within the heat exchange part (13a) and heated at the heat exchange part(13a) to the burner (7) and a low temperature air flow route (14) for feeding the outside air, which does not flow within the heat exchange part (13a) and thereby is lower in temperature than the outside air heated at the heat exchange part (13a), to the burner (7) is provided.

A catalytic reaction analysis dual reactor system and a method for measuring the catalytic activity of a catalyst by correcting for non-catalytic effects with the catalytic reaction analysis dual reactor system. The dual reactor system contains a first reactor comprising a first catalyst on a first catalyst support, and a second reactor comprising a second catalyst support, wherein the particle size and amount of the first catalyst and the second catalyst support are substantially the same, and the effect of the catalyst is isolated by correcting the result obtained from the first reactor containing the catalyst with the result obtained from the second reactor containing the catalyst support.
