Research on the application of catalytic materials in biomass pyrolysis

Biomass, as a very important renewable resource, its efficient conversion was an important way to achieve zero CO2 emissions, provide clean and renewable energy, and promote the resource utilization of agricultural waste. Biomass pyrolysis, as a technology that could simultaneously obtain high value-added energy and chemical products such as biochar, bio-oil, and combustible gas, had received widespread attention, in which the role of catalysts in biomass pyrolysis had also been widely studied. In this thesis, the application of catalysts in biomass pyrolysis was reviewed in detail on the basis of introducing the principle and pyrolysis methods of biomass pyrolysis, and found that catalysts could effectively improve the distribution and properties of pyrolysis products, especially for the reforming of bio-oil and bio-gas, which had shown outstanding performance in green energy and functional chemicals. At the same time, the current problems of catalysts in biomass pyrolysis were analyzed, and new thoughts were proposed for future research on biomass catalytic pyrolysis, with a view to providing new ways for efficient catalytic pyrolysis and green sustainable development of biomass.
