Patent number: 10800974Abstract: The present disclosure relates to a process for producing crude bio oil from biomass. The process involves hydrothermally liquefying a biomass in presence of a catalyst at a temperature in the range of 250° C. to 400° C. and at a pressure in the range of 70 bar to 225 bar, to obtain a product mixture comprising crude bio-oil. This product mixture comprising crude bio-oil is cooled to obtain a cooled mixture; the oil is then separated from the cooled mixture to obtain crude bio-oil and a residue containing the catalyst. Carbon content of crude bio-oil is in the range of 60 wt % to 85 wt %.Type: GrantFiled: November 30, 2017Date of Patent: October 13, 2020Assignee: RELIANCE INDUSTRIES LIMITEDInventors: Chidambaram Mandan, Balakrishnan Madhesan, Ramesh Bhujade, Ajit Sapre

Patent number: 10253265Abstract: The present disclosure relates to a process for catalyst assisted production of crude bio-oil from biomass, which involves heating a mixture of biomass slurry and a catalyst at a temperature ranging from 200 to 350° C. and at a pressure ranging from 70 to 250 bars to obtain a mass containing the crude bio-oil. The crude bio-oil is separated from said mass to obtain a separated crude bio-oil. The catalyst being soluble in water is recovered from the aqueous phase and is reused for the preparation of crude bio-oil from biomass.Type: GrantFiled: March 3, 2015Date of Patent: April 9, 2019Assignee: RELIANCE INDUSTRIES LIMITEDInventors: Kshudiram Mantri, Chidambaram Mandan, Ramesh Bhujade, Nagesh Sharma, Raksh Vir Jasra

Publication number: 20190083961Abstract: The present disclosure provides a multi-metallic catalyst system comprising at least one support, and at least one promoter component and an active component comprising at least two metals uniformly dispersed on the support. The present disclosure also provides a process for preparing the multi-metallic catalyst system. Further, the present disclosure provides a process for preparing upgraded fuel from biomass. The process is carried out in two steps. In the first step, a biomass slurry is prepared and is heated in the presence of hydrogen and a multi-metallic catalyst that comprises at least one support, at least one promoter component, and an active component comprising at least two metals to obtain crude biofuel as an intermediate product. The intermediate product obtained in the first step is then cooled and filtered to obtain a filtered intermediate product. In the second step, the filtered intermediate product is hydrogenated in the presence of the multi-metallic catalyst to obtain the upgraded fuel.Type: ApplicationFiled: November 9, 2018Publication date: March 21, 2019Applicant: RELIANCE INDUSTRIES LIMITEDInventors: Chidambaram MANDAN, Kshudiram MANTRI, Ramesh BHUJADE, Nagesh SHARMA, Raksh Vir JASRA

Patent number: 10138428Abstract: 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.Type: GrantFiled: September 28, 2015Date of Patent: November 27, 2018Assignee: Reliance Industries LimitedInventors: Kshudiram Mantri, Chidambaram Mandan, Ramesh Bhujade, Nagesh Sharma, Raksh Vir Jasra
