Definitions
- the invention relates to a process for the maturing of coal for coking, in which coal is ground, the grinding stock is mixed with a binder and a batch containing the binder mixed with the ground material is produced.
- the invention has for its object to provide a new method of the type mentioned for the Aufbereifung of coal for coking that carry out reliably with little technical effort Lässf.
- This object is achieved according to the invention in that a binder which is liquid or solid over the ambient temperature range is used.
- the disadvantages of water as a binder are advantageously avoided in the entire ambient temperature range which is approximately between the limits of -60 ° C. and + 60 ° C.
- solidification of the grinding material mixed with binder by freezing is excluded. Heating measures are eliminated.
- the bed of the invention can be advantageously processed into a coal cake and compacted in a mold and solidified into a block.
- the block formed from the bed of the invention has a particularly high stability.
- the bed can be coked directly in a suitable oven.
- binders viscous hydrocarbons of high molecular weight, especially tar.
- tar can be used, which is obtained during the subsequent coking process.
- the millbase and binder are mixed in such a ratio and over such a period of time that form from the carbon particles and the binder Agglomeratteilchen that unfold to the outside no adhesive effect and not adversely adhere to the container or means for compaction.
- the mixing takes place in such a way that the pourable agglomerate particles develop an external adhesive effect only under the influence of the compression pressure.
- a particularly strong and uniform solidification of the coal cake is achieved in this way during further processing of the bed to a coal cake by the compression.
- the coal cake is a largely homogeneous mold block.
- FIG. 1 shows a granule particle of carbon particles and tar binder used in the method according to the invention
- Fig. 2 is a compaction of a bed of granules of FIG. 1 to a coal cake explanatory illustration
- Fig. 3 shows a coal cake or mold block for the coking generated from the bed of Fig. 2.
- a bed e.g. Hard coal milled, with coal particles in grain sizes up to 6 mm.
- the coal particles are mixed with tar as a binder, as obtained in the subsequent coking of the bed.
- 90 to 95% by weight regrind are omitted, e.g. 5-10% by weight of the tar binder.
- the mixing takes place with circulation of the mixture mass over such a period of time that granulate particles 1 according to FIG. 1 are formed which consist of carbon particles 2 and the tar particles 3 holding the carbon particles 2, the tar binder 3 becoming so in the course of the granulation has withdrawn inside the Granulatteichen 1 that they are not sticky and the granules is therefore pourable without clumping.
- particles 1 of approximately the same mass and dimensions are formed.
- a bed can also contain distinctly different agglomerate or granule particles.
- the bed can be coking directly in a top-loading oven. Alternatively, it may be further processed to a coal cake as described below.
- granulate particles 1 are introduced into a molding box 5 while filling the bed 4 and compressed by means of a static or / and impulse-generating device 6. The introduction and compression of the granules in the molding box 5 takes place in layers in the example shown.
- the tar binder 3 remains effective over a wide temperature range.
