Embodiment Construction

[0010] The biomass raw materials such as straws with a moisture content of 10-20% are subjected to crushing pretreatment and quantitatively sent to the pyrolysis reactor. The pyrolysis reaction of biomass raw materials under the isolation of air occurs during the transportation process in the pyrolyzer. The pyrolysis temperature is 550-650℃, and the pyrolysis reaction time is at least 5 minutes. By monitoring the temperature and adjusting the flue gas heating device accordingly The load realizes the regulation of the pyrolysis reaction temperature. After pyrolysis, biomass raw materials are transformed into gas and solid phase products. The gas phase pyrolysis products include hydrogen, carbon monoxide, carbon dioxide, methane and other non-condensable gases at room temperature and tar and other macromolecular hydrocarbons that condense into liquid at room temperature. The basic reaction of pyrolysis is:

Abstract

A biomass hydrogen energy generating method is characterized in that using biomass thermal chemical hydrogen generating method to convert biomass into clean high-temperature hydrogen-abundant fuel gas, which can be directly used in fusion carbonate fuel battery without purification to generate electricity.

Description

Technical field [0001] The invention relates to a method of biomass hydrogen energy generation. Background technique [0002] With the shortage of fossil fuels and the increasingly tight energy supply situation, the development of biomass energy has attracted great attention. Biomass energy has the characteristics of abundant resources, huge reserves and renewable. Biomass power generation technology uses waste biomass resources such as straws to produce green power, which is of great significance for alleviating the shortage of power supply and ensuring energy security. The currently developed biomass power generation technologies mainly include biomass direct combustion power generation and gasification power generation. Direct combustion power generation uses biomass as boiler fuel to produce superheated steam, and realizes electricity production through steam turbines and gas turbines; gasification power generation uses fluidized bed, fixed bed and other forms of gasifiers to...
