CLAIMS

What is claimed is:

Process for the simultaneous extraction of lignin and silica from lignocellulosic plant material, characterized in that it comprises the steps of: a) fractionating the lignocellulosic plant material in the presence of an acid solution, so as to obtain a solid fraction comprising cellulose, residual lignin and silica;b) extracting simultaneously lignin and...

DESCRIPTION

Technical field of the invention

The invention relates to a process for the simultaneous extraction of a lignin and a silica, in particular a chemically unmodified lignin and silica, from lignocellulosic plant material and the use of the mixture obtained as a reinforcing filler for the mechanical reinforcement of elastomer polymers.
