  • Process and apparatus for the pre-treatment of biomass
    Patent number: 10124314
    Abstract: A process for pretreatment of biomass and an installation for practicing the process, the process including, as well, the subsequent biological treatment and obtaining of biofuel from the biomass. The process is based on the use of at least one scraped surface exchanger and comprises the following steps: heating the biomass to a temperature equal to or lower than 110° C. in an exchanger; further heating the heated biomass so obtained to a temperature between 150 and 175° C. in a scraped surface exchanger; thermal hydrolyzing the biomass at a temperature between 150 and 175° C.; and cooling the thermal hydrolyzed biomass for the subsequent biological treatment thereof.
    Type: Grant
