Abstract

Procédé de traitement d'un charbon sous-bitumineux et de charbons de mauvaise qualité contenant du calcium. Une solution d'un composé ou d'un sel répondant à la formule MX où M est H** +, un ion ammonium ou un cation monovalent ou multivalent, et X est un anion capable de former des composés de calcium insolubles, thermiquement stables, est maintenue en contact avec une charge de charbon particulaire, pendant un temps suffisamment long pour imprégner le sel ou le composé dans les pores du charbon. Application à l'amélioration de la liquéfaction du charbon.Process for treating sub-bituminous coal and low-quality coals containing calcium. A solution of a compound or a salt having the formula MX where M is H ** +, an ammonium ion or a monovalent or multivalent cation, and X is an anion capable of forming insoluble, thermally stable calcium compounds , is maintained in contact with a particulate carbon filler, for a time long enough to permeate the salt or compound into the pores of the carbon. Application to the improvement of the liquefaction of coal.
