Patent number: 11878983Abstract: A method of producing levoglucosenone from particulate cellulosic material. The method comprises forming a premix of particulate cellulosic material, water, acid and a polar organic solvent. The solvent has a higher boiling point than levoglucosenone. The pre-mix is fed into a pyrolysis reactor, such as a fluidised bed reactor, in which the pre-mix is fluidised by a fluidising gas. The reactor is maintained at a temperature within the range 250° C. to 450° C., and gaseous products and char are withdrawn from the pyrolysis reactor. Levoglucosenone and the polar organic solvent are condensed from the gaseous products, produced by the reactor.Type: GrantFiled: August 15, 2019Date of Patent: January 23, 2024Assignee: CIRCA GROUP LIMITEDInventors: Anthony James Duncan, Ebbe Jan Dommisse, Warwick Douglas Raverty
