A process for treating lignocellulosic material, for example, straw, uses a nitrogen containing acid, a nitrogen containing organic acid or a soluble salt of these acids in conjunction with an accelerating agent which is a strongly ionising water soluble substance to release the cellulosic and ligneous components. The acid may be sulphamic acid used in conjunction with magnesium sulphate as the accelerating agent. In a second stage of the process a neutralising alkaline agent may be used to separate out the ligneous component. The process may be a semi-dry process conducted under atmospheric pressure and at temperatures up to 100 DEG C. End products suitable for use in papermaking and/or for animal feed may be produced by the process. |
