Abstract

LA PRESENTE INVENTION DECRIT UNE SUSPENSION AQUEUSE DE CHARBON CONTENANT DEUX GROUPES SEPARES DE PARTICULES DANS LESQUELS LES PARTICULES DU PREMIER GROUPE ONT UNE TAILLE MOYENNE COMPRISE ENTRE 210 ET 60 MM, LE MAXIMUM NE DEPASSANT PAS 300 MM, ET LES PARTICULES DU SECOND GROUPE ONT UNE TAILLE MOYENNE COMPRISE ENTRE 16 ET 120 DE LA TAILLE MOYENNE DES PARTICULES DU PREMIER GROUPE. LA COURBE DE DISTRIBUTION GRANULOMETRIQUE CUMULEE PORTEE SUR UNE ECHELLE BILOGARITHMIQUE MONTRE UNE ZONE PLATE SITUEE ENTRE LES VALEURS D ET D REPRESENTANT LES TAILLES MOYENNES DES DEUX GROUPES DE PARTICULES DE CHARBON. EN PLUS DU CHARBON ET DE L'EAU, LA SUSPENSION CONTIENT UN POLYELECTROLYTE ANIONIQUE NON-TENSIOACTIF AYANT UN PM500 ET EVENTUELLEMENT UN STABILISANT DU TYPE GEL ORGANIQUE. UTILISATION DE CETTE SUSPENSION A TRES HAUTE CONCENTRATION EN CHARBON POUR FACILITER LE TRANSPORT DE CELUI-CI OU DIRECTEMENT COMME COMBUSTIBLE
