| 20100203608 | METHOD FOR THE CONVERSION OF BIOMASS FROM RENEWABLE RAW MATERIALS IN ANAEROBIC FERMENTERS - The invention relates to the field of biochemistry and relates to a method that is used in a biogas production plant. The object of the present invention is a method which realizes a shorter total retention time of the raw materials in the biogas plant and/or a higher quantity and/or quality of the biogas. The object is attained through a method in which renewable raw materials are placed in an at least first anaerobic fermenter/reactor together with liquid and further starting materials necessary for methanogenesis, and there subjected to a fermentation process. Subsequently the fermentation residue is subjected to a solid/liquid phase separation and the separated solid phase is subjected to thermopressure hydrolysis at temperatures of at least 170° C. and pressures of at least 1.0 MPa. The solid phase thus treated may either be returned to the first anaerobic fermenter/reactor or fed to a second anaerobic fermenter/reactor and subjected to a further fermentation process. | 08-12-2010 |

| 20100288709 | PROCESS AND APPARATUS FOR IMPROVING THE DISINTEGRATION OF THIXOTROPIC SUSPENSIONS BY MEANS OF ULTRASOUND - A method for a disintegration of a thixotropic suspension by ultrasound, includes diverting at least one partial flow from a total suspension flow downstream of an ultrasonic treatment unit, increasing a flow rate of the at least one partial flow and mechanically stressing a thixotropic suspension flow. Additionally, the method includes adding the at least one partial flow to the stressed thixotropic suspension flow to establish the total suspension flow and ultrasonically treating the total suspension flow. | 11-18-2010 |
