Definitions

  • the subject of present invention is a method of forming of the wet rines and coal silts, and an equipment suitable for applying the method.
  • the object of present invention is to eliminate all the deciencies and inconveniences present with the available and used methods of forming of wet fines and coal silts while its aim consists in developing of a new forming method and designing of an equipment which would be suitable for application of this method.
  • This object has been attained in such a manner that the wet nes or coal silt which is introduced into the mixing vessel is sprinkled with a binding agent comprising a residue obtained in the treatment of petroleum at the AICC rate of 5-10 percent by Weight in proportion to the Wet fines or coal silt and, while the substance is mixed, it is subjected to the action of super heated to 250 C. steam which is introduced to the mixing vessel at the rate of 1-3 tons per hour in proportion to 1 ton of the wet lines or coal silt and against the direction of the moving coal mixture, said binding agent being such a residue as for instance the distillation residue, pressure still tar, hydro-cracking or pyrolysis residue to which an aluminosilicate catalyzer is added at the temperature of 250 C.
  • a binding agent comprising a residue obtained in the treatment of petroleum at the AICC rate of 5-10 percent by Weight in proportion to the Wet fines or coal silt and, while the substance is mixed, it is subjected to the action of super heated to 250
  • the means for application of this method combines a mixing vessel provided with a mechanical mixer coupled with the mechanism of a discharging worm, and a tube ring through which the superheated steam is introduced to the mixing vessel.
  • Substantial technical advantage oiered by the invented method is comprised in the possibility of conducting the drying process of the -wet iines or coal silt and the process of mixing it with the bindingagent in the form obtained in the treatment of petroleum residue, rWithin a single installation system of a simple construction while the danger of forming of explosive mixtures is entirely eliminated. Further technical vantage point is: that the properties of the end product obtained by application of this method are resembling the value properties of the coals.
  • the substance of invention is depicted in the drawing 1n which presented is the diagram of an equipment developed and suitable for forming of wet iines or coal silts according to the invented method.
  • Coal lines or coal silt containing about 30 percent Of water is delivered from a reservoir 1, by means of worm mechanisms 2, to mixing vessel 3 where it is sprinkled with the binding agent at the rate of 10 percent by weight in proportion to the amount of coal lines or coal silt.
  • the binding agent is delivered, by means of a pump 4, from a tank 5 in which the said residue in form of distillation residue, pressure still tar, hydro-crackingor pyrolysis residue.
  • the mixing vessel 3 is provided with a mechanical mixture 7 of high efficiency Whose arms are fitted with steel Scrapers preventing sticking of the mixture to the walls of the mixing vessel, and with a perforated tube ring 8 through which the steam superheated to the temperature of 250 C.
  • a method of developing shapable wet iines or coal silt material comprising introducing said material into a mixing vessel, admixing a binding agent obtained in the treatment of petroleum with said material in an amount of 5-10% by weight of said material and countercurrently subjecting said mixture to superheated steam at a temperature of 250 C. in an amount of steam of 1 to 3 times the amount of material.
