Title: PROCESS FOR PRODUCING HYDROGEN BY MEANS OF ADSORPTION CATALYSIS OF CRUDE SYNTHETIC GAS, AND DEVICE THEREFOR
Abstract:
Provided is a process for producing hydrogen by means of the adsorption catalysis of a crude synthetic gas, comprising the following steps: 1) mixing water vapour and a crude synthetic gas in a water-carbon molar ratio of 2 to 6 : 1, adding a reduced reforming catalyst with an adsorption function, and carrying out a reforming hydrogen-producing reaction in a fluidised state; 2) subjecting the reforming catalyst after the reaction to high-temperature combustion so as to oxidise and remove a carbon deposit and sulphur-containing components thereon, and heating the reforming catalyst so as to release CO2 and realise regeneration; and 3) subjecting the regenerated reforming catalyst to in-situ reduction at 400ºC to 900ºC, and recycling the resulting reduced reforming catalyst for hydrogen production to obtain a product, namely, hydrogen. Also provided is a device for producing hydrogen by means of the adsorption catalysis of a crude synthetic gas. By means of the method, the crude synthetic gas containing tar and sulphur can be further converted into hydrogen, so that the steps of the sulphur removal and tar separation of the crude synthetic gas are omitted, and the selection range of hydrogen-producing raw material gases is greatly broadened; the reforming catalyst is reduced in-situ, without a reduction procedure needing to be additionally arranged; and the device saves the use of auxiliary apparatuses such as a degassing tank and a reduction reactor, such that the procedure is greatly simplified.
