Description

The experimental study of the uranium-lignite association has been investigated at different temperatures from 20 to 4000C. Fixation of uranyl species by the lignite (45 to 2500C) and reduction of them to uraninite (120 to 4000C) were observed. The reduction of uranium is accompanied by dehydrogenation of the lignite

Abstract (French)

L'association uranium-lignite est etudiee experimentalement a des temperatures de 20 a 4000C. On observe la fixation d'especes chimiques uranylees par le lignite (45 a 2500C) et la reduction de ces especes en uraninite (120 a 4000C). Cette reduction de l'uranium s'accompagne d'une dehydrogenation du lignite
