Abstract

Concentration of kerogen of the Hungarian alginites can be carried out by separation in organic solvents. This method is very quick, it does not need a lot of work and the solvent can be removed without residue. Applying other physical method, e. g. separation in calcium chloride solution the amount of the kerogen concentrate is larger but its organic carbon content smaller than using chloroform for separation. The quality of the organic phase is better if solvents of lower specific gravity are used. As the other physical separation methods, this one has also the disadvantage that the kerogen of samples of low organic content can not be separated. Acidic treatment of the samples of high carbonate and relatively low organic carbon content promotes the separation by physical method.
