Description

Technical Field

[0001] The invention relates to the field of pyrolysis / gasification devices, and in particular to a device and method for preparing adjustable synthesis gas by two-stage adsorption enhancement of organic solid waste. Background Art

[0002] As "carbon neutrality" becomes one of the important topics in the world, reducing dependence on fossil fuels is the key to reducing carbon emissions. Multi-source organic solid waste such as biomass and domestic waste is one of the most promising alternatives to fossil fuels. Pyrolysis / gasification is considered to be one of the most promising organic solid waste conversion technologies, which can convert renewable energy such as biomass and domestic waste into high-value syngas. However, the syngas produced by pyrolysis / gasification cannot be directly used for the synthesis of downstream products. The adjustment of the molar ratio of H2 to CO in the syngas plays an important role in the synthesis of downstream products (H2 / CO=2:1 in methanol production, H2 / CO=1:2 in Fischer-Tropsch synthesis, and H2 / CO=1:1 in dimethyl ether production). Therefore, how to obtain syngas with a coordinated H2 / CO ratio in the pyrolysis / gasification process of organic solid waste is a challenge.

[0003] China's invention patent CN110066670A discloses a "biomass continuous catalytic pyrolysis method and integrated device for catalyst regeneration". This device combines the two processes of catalytic pyrolysis and catalyst regeneration, which are usually separated, in the same device, achieving graded utilization of heat, high energy utilization efficiency, energy saving and environmental protection. However, this solution cannot further collect and utilize the CO2 generated during the pyrolysis / gasification process.

[0004] In order to meet the needs of different chemical synthesis processes, the H2 / CO molar ratio of syngas needs to be precisely adjusted. This requires the development of technologies that can flexibly adjust the H2 / CO ratio to suit different industrial applications. Summary of the invention
