Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, the present invention includes preheating device, steam generator, reforming reactor, heating furnace, purification tower and air cooling chamber;

[0027] The bio-oil is sent to the reforming reactor after being preheated by the preheating device, and the steam generator sends water vapor into the reforming reactor, and the iron ore and calcium oxide are respectively sent to the reforming reactor through the feeding device. The heating furnace produces high-temperature flue gas to provide heat for the reforming reactor;

[0028] Bio-oil, iron ore, water vapor, and calcium oxide are catalytically reformed in the reforming reactor to generate crude hydrogen-rich synthesis gas and high-temperature carbon-coated iron ore;

[0029] The crude hydrogen-rich synthesis gas is sent to a purification tower, condensed ...

Description

technical field [0001] The invention belongs to a system for preparing hydrogen-rich synthesis gas by catalytic reforming of bio-oil, in particular to a system for preparing hydrogen-rich synthesis gas by catalytic reforming of bio-oil with iron ore. Background technique [0002] As the main product of biomass pyrolysis and liquefaction, bio-oil has the advantages of high energy density, convenient transportation and storage, easy further processing and large-scale centralized utilization. Hydrogen production by catalytic reforming of bio-oil is an important way for high-value utilization of bio-oil. Catalytic reforming of bio-oil for hydrogen production uses catalysts to increase the activity of bio-oil cracking and gasification, thereby greatly reducing the temperature of cracking and gasification. It is currently a more feasible means of bio-oil utilization. At present, there are mainly carbonate-based natural ore catalysts represented by dolomite and transition metal ca...
