Definitions

  • the invention relates to a method for the treatment of water-rich coals, in particular lignite, by heating a mixture of. Raw coal and hydrocarbons.
  • the invention has for its object to improve a method of the type described above, the lower water content of the coal can be achieved.
  • the invention proposes that a mixture of finely ground raw coal, a heavy hydrocarbon oil and light hydrocarbons is heated to 50-300 ° C. with a residence time of 0.1-30 minutes, with water and light hydrocarbons being removed simultaneously the mixture is separated, the light hydrocarbons are recycled to form the mixture and the water and the remaining mixture of the coal and the heavy hydrocarbon oils are removed from the process.
  • the raw coal can be ground to the fineness required for the hydrogenation before being mixed into the hydrocarbon oils, but advantageously also in a mixture with these.
  • the mixture can be prepared in the usual way.
  • the ratio of coal, calculated anhydrous, to the heavy hydrocarbon oil will generally be chosen between 1: 2 and 1: 0.7, preferably with the highest possible coal concentrations.
  • a quantity of light hydrocarbons should be added to the mixture in such a way that it is sufficiently pumpable.
  • the ratio of serious Light hydrocarbon oils can be selected between 1: 3 and 1: 0.25 depending on the use of the former oils.
  • Heavy hydrocarbon oils used are generally heavy oil or residue fractions boiling above about 200 ° C. which originate from coal hydrogenation, but corresponding foreign oils can also be used.
  • the prepared mixture is then, optionally after preheating, introduced into an apparatus suitable for the heat treatment with simultaneous removal of water and light hydrocarbons, e.g. B. in a distillation column or a falling film evaporator.
  • the heat treatment is carried out at temperatures of about 50 to 300 ° C., optionally at elevated pressures of up to about 10 bar, for a period of 0.1 to 30 minutes.
  • the water and hydrocarbon vapors obtained are condensed in a conventional manner and separated from one another.
  • the hydrocarbons are returned to the raw coal mixer and the water is removed from the process.
  • the coal / heavy oil mixture obtained from the treatment apparatus can be fed directly to the coal hydrogenation, which can be carried out in a known manner.
  • the water contents in these mixtures are less than 8% by weight, based on the coal. In general, values of 5% and lower can be achieved. Design example:
  • Raw lignite is introduced via line 1, a high-boiling oil originating from the coal hydrogenation via line 2 and a light petrol likewise originating from the hydrogenation is introduced into the mixing apparatus 4 via line 3.
  • the mixture passes through line 5 in a rotary drum 16, in which generally at a slightly elevated temperature, for. B. 50 - 80 ° C, a fine grinding takes place.
  • the mixture is then introduced via line 7, the preheater 8 and line 9 into the heat treatment apparatus 10, which is shown here as a falling film evaporator.
  • the heat treatment takes place with sufficient duration, in the course of which the water and gasoline vapors formed are drawn off via line 13.
  • the coal / oil mixture subsequently provided for hydrogenation with a water content of z. B.
  • the water and gasoline vapors are condensed in the condenser 14, the liquids obtained are fed via line 15 into the phase separation 16 and there into a gasoline stream, which is returned via line 3 to the mixing apparatus 4, and into a water stream, which is discharged via line 17 the process is removed.
  • Finely ground Australian lignite with a water content of 55% by weight was dried in a conventional manner by heating to a water content of 10% by weight.
  • the mixture thus obtained, coal content 40%, was so highly viscous that it was not pumpable.
  • a mixture of coal, heavy oil and xylene, ratio 1: 1: 1, was then produced from Australian brown coal and treated according to the invention at 150 ° C. for 20 minutes.
  • the water content of the coal / heavy oil mixture intended for the hydrogenation, coal content 50% by weight, was less than 1% by weight, based on the coal.
  • the mixture was pumping itself.

Abstract

Dans ce procede de traitement par chauffage d'un melange de charbon brut et d'huiles hydrocarbonees, on chauffe a une temperature de 50 a 300 C un melange de charbon brut finement divise, d'une huile lourde hydrocarbonee et d'hydrocarbures legers pendant 0,1 a 30 minutes; de l'eau et des hydrocarbures legers se separent simultanement du melange. Les hydrocarbures legers peuvent etre ajoutes au melange en circuit ferme. On elimine du processus d'une part l'eau et d'autre part le melange restant compose de charbon et d'huiles lourdes hydrocarbonees. En reunissant en une seule etape le chauffage du melange et sa separation en ses composants, on peut reduire considerablement la teneur en eau du charbon. De plus, il est facile de proceder de facon que le melange de charbon et d'huiles hydrocarbonees puisse etre transporte par pompage.
