CATALYST ASSISTED CONVERSION OF BIOMASS TO BIO-OIL

摘要

The present disclosure relates to a process for the production of crude bio-oil which involves heating a mixture of biomass slurry and a mixed catalyst system in the presence of a hydrogen source at a temperature ranging from 200 to 350° C. and at a pressure ranging from 70 to 250 bars to obtain a mass containing crude bio-oil. The crude bio-oil can then be separated from said mass containing crude bio-oil. The mixed catalyst system remains in solid form and can be easily separated and reused in the next cycle of hydrothermal conversion of biomass to crude bio-oil.

主权项

1. A process for preparing bio-oil, said process comprising:
a. preparing and/or collecting a biomass slurry; b. adding a mixed catalyst system to the biomass slurry to obtain a mixture; c. heating said mixture in the presence of a hydrogen source at a temperature ranging from 200 to 350° C. and at a pressure ranging from 70 to 250 bars for a time period ranging from 10 to 180 minutes to obtain a mass containing crude bio-oil; and d. separating the crude bio-oil from the mass containing crude bio-oil to obtain a separated crude bio-oil and a sludge containing a residue and the mixed catalyst system.
