The biomass fuel technology achievements of the Guangzhou Institute of Energy of the Chinese Academy of Sciences passed the appraisal

Recently, the mechanism of aqueous catalytic conversion of biomass and the technology of biomass hydrocarbon fuel completed by the Guangzhou Institute of Energy Resources, Chinese Academy of Sciences have passed the identification
.
The expert group believes that the results are internationally leading
in the catalytic conversion of biomass aqueous phase into bio-aviation fuel.

In this achievement, the dynamic liquid film effect mechanism of complex multiphase flow and reaction synergy of biomass hydrothermal depolymerization is proposed, a hydrothermal multiphase depolymerization system and a water vapor stripping-acid salt depolymerization system are constructed, an efficient catalytic system for hydrothermal conversion of biomass with high hydrothermal stability is developed, and the regulatory mechanism of "synergistic reaction and spatial binding effect" composed of regular pore structure and catalytic active site on the transformation pathway is proposed to fill the domestic gap
.

In addition, the results propose a new mechanism of carburization isomerization based on self-condensation and cross-condensation of furan platform compounds, invent a new technology of carbonization isomerization and aqueous aromatization of biomass to hydrocarbon fuel, realize the co-conversion of hemicellulose and cellulose in biomass to synthesize bioaviation fuel, build the world's first 100-ton pilot plant for the synthesis of biogasoline and aviation fuel by aqueous phase catalysis of biomass such as straw, the oil quality reaches the international ASTM7566 standard, and propose a large-scale production mode of "decentralized degradation into intermediates - centralized hydrogenation to oil"
