  • Catalyst composition and a catalytic process for conversion of biomass to crude bio oil
    Patent number: 10118159
    Abstract: The present disclosure provides a catalyst composition for conversion of biomass to crude bio oil. The composition comprises at least one metal compound, at least one support and at least one stabilizing/solubilizing agent. Also disclosed are processes for the preparation of catalyst composition, and hydrothermal conversion of biomass to crude bio oil.
    Type: Grant
    Filed: May 8, 2014
    Date of Patent: November 6, 2018
    Assignee: Reliance Industries Limited
    Inventors: Chidambaram Mandan, Kshudiram Mantri, Supriya Apegaonkar, Ramesh Bhujade, Nagesh Sharma, Raksh Jasra
  • Process for the production of bio-oil
    Patent number: 9909072
    Abstract: The present disclosure relates to a process for the production of bio-oil which involves heating a mixture of a biomass slurry and a first catalyst composition 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, a residue and the catalyst; separating the crude bio oil from said mass to obtain a separated crude bio oil; extracting said separated crude bio oil with at least one solvent and evaporating said solvent to obtain a solvent free crude bio oil; subjecting said solvent free crude bio oil to reduction in the presence of a second catalyst composition and hydrogen source at temperature and pressure conditions similar to those employed for the conversion of bio mass into crude bio oil to obtain bio-oil. The second catalyst composition is the same as that of the first catalyst composition.
