  • Publication number: 20230021045
    Abstract: A method for co-production of monophenols and cellulose by transition metal oxide catalytic oxidation of biomass is disclosed. The method uses transition metal oxide as catalyst and pretreated dry biomass as raw material to obtain high purity and selectivity of monophenolic chemicals with co-produced cellulose under mild conditions.
    Type: Application

  • Patent number: 8562697
    Abstract: The invention discloses a process for hydrolyzed reforming of the ligneous cellulose biomass to produce bio-gasoline, which directly transfers the hydrolyzed-material liquid obtained from ligneous cellulose biomass through hydrolyzing into aqueous catalytic reforming system, the feed subjects to aqueous catalytic reforming reaction in low-temperature reforming reactor filled with catalyst Ni/SiO2—Al2O3 and in high-temperature reforming reactor filled with catalyst Ni/HZSM-5 in turn, the reactant is condensed and phase-separated: uncondensed bio-gasoline is absorbed by absorption liquid-C6 alkane, condensed liquid is phase-separated through phase-separator, bio-gasoline is obtained in the upper layer of the phase-separator. The invention creates a new process for producing high-quality liquid fuel oil using biomass as feedstock, which can automatically layer and separate, omitting the step of rectifying and purifying product. The feedstock is cheap and broadly available.
