Claims9
A process for the production of furfural from lignocellulosic material comprising the steps:
- a) treating lignocellulosic material by applying steam to release furfural into said steam;
- b) separating the steam containing furfural from the treated cellulosic material;
- c) transferring the separated steam to a segregation device;
- d) segregating the phase containing furfural from the steam;
- e) subjecting the steam to a utilization step;
- wherein segregating according to step d) is carried out by adsorption and wherein the utilization step e) is heating.
