  • Method of treatment of aqueous effluent
    Patent number: 10919871
    Abstract: A method of treatment of an aqueous effluent stream obtained during production of furfural is disclosed. The aqueous effluent stream containing organic solvents, furfural, and water is subjected to azeotropic distillation to obtain a distillate stream and a treated effluent stream having lower BOD and COD values which can be further reduced by biomethanation.
    Type: Grant
    Filed: June 1, 2017
    Date of Patent: February 16, 2021
    Assignee: BASF SE
    Inventors: Sunil Sadashiv Divekar, Pramod Shankar Kumbhar, Rahul Vasantrao Bagal, ShreekantUttam Satav

  • Preparation of Furfural using mixed solvents
    Patent number: 10040774
    Abstract: Processes for the preparation of furfural from a xylose containing feedstock and more particularly to an elevated temperature conversion of a xylose containing feedstock to furfural in acidic conditions are described. The described process uses a mixture of two solvents in which the humins are formed and solubilized. The described process is operated in continuous mode with no significant amounts of solid by-products formation.
