Methods and compositions are provided for increasing packed bulk density of coal, whose surface moisture varies from 5 to 15 weight percent, to desired levels in the range of 45 to 50 lbs./cu.ft., and for controlling and maintaining the improved bulk density. The method involves treating the coal with dilute water solutions (0.01 to 1.0 weight percent of solids) of water soluble, nontoxic polymers, belonging to the classes of polyethylene oxides and polyacrylamides, in amounts between .5 gram and 120 grams of polymer solids per metric ton of coal.

L'invention se rapporte à des procédés et compositions permettant d'accroître la masse volumique tassée du charbon, dont l'humidité de surface varie entre 5 et 15 % en poids, jusqu'à ce qu'elle atteigne des niveaux requis compris entre 45 et 50 livres/pied cube, et permettant également de réguler et de maintenir cette masse volumique améliorée. Le procédé consiste à traiter le charbon avec des solutions aqueuses diluées (contenant de 0,01 à 1,0 % en poids de solides) de polymères non toxiques, solubles dans l'eau, appartenant aux catégories des oxydes de polyéthylène et des polyacrylamides, et présentes en quantités comprises entre 0,5 g et 120 g de solides polymères par tonne métrique de charbon.
