摘要 |
It is described a process for thermal hydrolysis and team explosion of biomass, said method comprising the steps of: (i) leading the biomass approximately continuous to a first preheating step and preheat the biomass, (ii) leading the preheated biomass into at least two reactors sequentially, (iii) heating and pressurising the reactor by addition of steam, (iv) keeping the reactor(s) at a certain temperature and pressure for a certain time, (v) leading the heated and pressurized biomass from the reactor(s) to a first pressure relief tank without any substantial pressure reduction and quickly relief the pressure of the biomass by means of a nozzle, in order to disintegrate the biomass, (vi) leading the biomass from the first pressure relief tank to a second pressure relief tank having a lower pressure than the pressure of the first pressure relief tank, (vii) leading the so treated biomass to a downstream facility for subsequent treatment. The invention also comprises a device for thermal treatment of biomass. |
