Abstract

Two physically separated, co-existing lithotypes of German brown coal (a structured 'woody' and an 'amorphous' lithotype) were subjected to ruthenium tetroxide (RuO4) oxidation and pyrolysis-g.c.-m.s.. Both techniques provided results that indicated quite different origins for the two fossil fuel types. Particularly obvious in the oxidation products were lignin-derived aromatic acids corresponding to some of the phenolic pyrolysis products (more prevalent in the 'woody' material) and higher plant liptinite derived acids correlating with alkene/alkane doublets in the pyrolysates (more prominent in the 'amorphous' sample), reflecting these differences.
