Beschreibung
Zusammenfassung:	Method of delignification of plant material, said method comprising:providing said plant material comprising cellulose fibres and lignin;exposing said plant material requiring to a composition comprising:an acid;a modifiying agent selected from the group consisting of: sulfamic acid; imidazole; N-alkylimidazole; taurine; a taurine derivative; a taurine-related compound; alkylsulfonic acid; arylsulfonic acid; triethanolamine; and combinations thereof;a metal oxide; anda peroxide;for a period of time sufficient to remove substantially all (at least 80%) of the lignin present on said plant material.
