<p>Chemical treatment of bulky organic materials, in particular straw and other biomass, with volatile chemicals, such as NH3, SO2, HF, HCl, which is added to the material before, during or after a (semi)continuous compression, in particular in a piston press (1) or an extruder, and then the reaction mixture is kept enclosed and heated in a reaction chamber (6) at an elevated temperature and pressure for a period sufficient to cause the intended conversion of the material. In the treatment straw can be converted to readily digestible feeds or to fiber products for use paper or cardboard products or be pre-treated with a view to complete hydrolysis aqueous acid or enzymes.</p> |
