Abstract

Liquéfaction des matières charbonneuses dans une installation à étages multiples avec donneur d'hydrogène. Le procédé comprend : a. La séparation d'une quantité suffisante de la fraction à bas poids moléculaire d'avec la fraction de liquide à poids moléculaire élevé pour former un courant de résidus lourds contenant moins de 50 % en poids environ de la fraction liquide à bas poids moléculaire, par rapport au poids de la fraction liquide à poids moléculaire élevé; b. La mise en contact du courant de résidus lourds avec un solvant supplémentaire donneur d'hydrogène et un gaz contenant de l'hydrogène, dans des conditions de liquéfaction, dans une seconde zone de liquéfaction ; c. La séparation de l'effluent provenant de la seconde zone de liquéfaction en une fraction de vapeurs et une fraction de liquide; et d. La récupération des produits hydrocarbonés liquides à partir des fractions de vapeurs et de liquide. Application à la production d'hydrocarbures liquides à partir du charbon.Liquefaction of carbonaceous materials in a multi-stage installation with a hydrogen donor. The method includes: a. Separating a sufficient amount of the low molecular weight fraction from the high molecular weight liquid fraction to form a heavy residue stream containing less than about 50% by weight of the low molecular weight liquid fraction, by relative to the weight of the high molecular weight liquid fraction; b. Contacting the heavy residue stream with an additional hydrogen donor solvent and a hydrogen-containing gas, under liquefaction conditions, in a second liquefaction zone; vs. Separating the effluent from the second liquefaction zone into a vapor fraction and a liquid fraction; and D. The recovery of liquid hydrocarbon products from the vapor and liquid fractions. Application to the production of liquid hydrocarbons from coal.
