ABSTRACT:
The invention relates to a lignin preparation prepared from black liquor derived from an alkali delignification process, such as the sulphate process, soda process or polysulphide process. The lignin preparation comprises mainly lignin and at least the major part of the sodium content of the lignin separated from the black liquor deriving from such processes has been replaced with calcium, therewith to provide a lignin preparation having improved properties which render the preparation more suitable for use as fuel.
