Publication number: 20130337523Abstract: A process for the treatment of biomass is provided. The process comprises forming a biomass slurry by mixing biomass with a working fluid, and inducing the biomass slurry to flow through an inlet into a passage. A high velocity transport fluid is injected into the slurry through a nozzle communicating with the passage. The injection of the high velocity transport fluid applies a shear force to the slurry such that the working fluid is atomised and forms a vapour and droplet flow regime, an at least partial vacuum is formed within the passage downstream of the nozzle, and a condensation shock wave is generated within the passage downstream of the nozzle and vacuum by condensation of the transport fluid. An apparatus for treating biomass using the aforementioned process is also provided.Type: ApplicationFiled: August 15, 2013Publication date: December 19, 2013Inventors: John Gervase Mark Heathcote, Marcus Brian Mayhall Fenton

Publication number: 20100129888Abstract: The present invention provides processes for the treatment of a starch-based feedstock. The processes include mixing together a starch-based feedstock and a working fluid to form a slurry, hydrating the starch-based feedstock with the working fluid, adding an enzyme to the slurry, pumping the slurry into a substantially constant diameter passage of a fluid mover, and injecting a high velocity transport fluid into the slurry through one or more nozzles communicating with the passage, thereby further hydrating the starch-based feedstock and activating the starch content of the slurry. Apparatuses for carrying out such processes are also provided. Processes for converting a feedstock to a polysaccharide and systems for producing ethanol using the processes and apparatuses of the invention are also provided.Type: ApplicationFiled: November 2, 2009Publication date: May 27, 2010Inventors: Jens Havn Thorup, John Gervase Mark Heathcote, Marcus Brian Mayhall Fenton
