  • Phycocyanin extraction and production of crude bio-oil from biomass
    Patent number: 10195585
    Abstract: The present disclosure relates to a process for the conversion of biomass to crude bio-oil. Phycocyanin is extracted from the biomass to form phycocyanin extracted biomass (PEB) and subjecting the PEB to HTL conversion to obtain crude bio-oil. PEB results in improved yield of crude bio-oil as compared to the crude bio-oil yield from biomass without first extracting the phycocyanin from the biomass.
    Type: Grant
    Filed: December 29, 2015
    Date of Patent: February 5, 2019
    Assignee: Reliance Industries Limited
    Inventors: Badrish Ranjitlal Soni, Mandan Chidambaram, Kshudiram Mantri, Vijayakumar Vinodhkumar, Sasanka Raha, Venkatesh Prasad, Ramesh Bhujade, Santanu Dasgupta, Nagesh Sharma, Raksh Vir Jasra

  • Method of reducing or maintaining the value of an alkylene oxide production parameter in a process of making an alkylene oxide using a high efficiency catalyst
    Patent number: 9181207
    Abstract: Methods of reducing or maintaining the value of an alkylene oxide production parameter (such as alkylene oxide production rate) in a process of making an alkylene oxide by reacting an alkylene and oxygen over a high efficiency catalyst are shown and described. One method comprises reducing the concentration of oxygen in the reactor feed gas to reduce or maintain the value of the alkylene oxide production parameter.
