| 20110251440 | METHOD AND APPARATUS FOR PRESSURIZING AND HEAT-TREATING A FLOWABLE SUSPENSION - A method of continually heat-treating a biogenic material in the production of fuels such as ethanol or biogas includes pressurizing the biogenic material with a first pump so as to provide a pressurized suspension. The pressurized suspension is continuously heat-treated at a heat-treatment temperature of from 100° C. to 180° C. in a hydrolysis reactor so as to provide a heat-treated suspension. A temperature of the heat-treated suspension is lowered to below 100° C. The heat-treated suspension is depressurized with a second pump. The first and second pumps are configured to maintain at least one of the pressurized suspension and the heat-treated suspension at a pressure of above 5 bar. | 10-13-2011 |
| 20110247608 | METHOD AND DEVICE FOR TREATING BIOGENIC MATERIAL - A method of subjecting a flowable suspension comprising a biogenic material to a temperature hydrolysis includes passing the flowable suspension through a first downward conduit section. The flowable suspension is passed through a first connecting conduit section and a first upward part. The first connecting conduit section is configured to connect an outlet of the first downward conduit section with an inlet of a second downward conduit section. The flowable suspension is passed through the second downward conduit section. A first flow velocity in the first upward part exceeds a second flow velocity in each of the first downward conduit section and the second downward conduit section. | 10-13-2011 |
