PROCEDURE FOR THE USE OF CARBON WASTE AND CARBON FUELS
The present invention relates to processes for the utilization of coal waste: coke mill, coal and blast furnace recycled materials as by-products of environmental pollution, waste and fuels derived from coal waste.
In the past, coke coarse (as a by-product of coke production), fine coal (as a by-product of coal mining) and blast furnace recyclates (as by-products of iron making) were simply discarded in large quantities, causing a source of environmental contamination and fire.
Coke is a pure coal with high calorific value, a pure combustion fuel used primarily in iron and other industries. It is made of metallurgical grade coal which is ignited in large furnaces without the presence of air. The volatiles are removed from the carbon and only the pure carbon remains. Smaller pieces of coke - coke dust and coke mill - represent a loss in coke production. Coke dust has accumulated as waste for years as a result of the above-mentioned coking process. Waste coke dust vases do not provide a beautiful sight and are eternal sources of environmental pollution.

First Example
As shown in Figure 1, 90.72 kg (200 lbs.) Of wet carbon powder 1 is placed in a mixer 2. The water content was determined by measurement at 30%. Thus, the mixture is relatively dry. The substance is stirred until evenly distributed in water. Stirring for about 10 minutes is usually sufficient. A large amount of carbonic acid is removed from the carbon, which will result in the pH of the adhesive mentioned above.
A hygroscopic solvent 3 (methyl ethyl ketone) in which 10% by volume of 4 styrene polymer resin 5 was dissolved was added to the mixer at 7% by weight. The material in the mixer is stirred until the solvent 3 is completely dissolved in a mixture of carbon powder and water. 10 minutes is usually sufficient.
7% emulsion 6a polyvinyl acetate - 6b water 7b was added and stirred until homogenized. The resulting mixture is briquetted using a conventional briquetting machine at a pressure of 20 MPa.
Example 2:
Remaining at Figure 1, the process described above is repeated with dry coke 9. The preparation of the coke-water mixture 9, from which solid briquettes 11 can be obtained, requires less water 10.
About 10% by weight of water is added to the dry coke 9 and stirred until homogeneous (several times for 10 minutes). The steps of Example 1 are repeated and in the final step heavy briquettes are pressed on an 8 briquetting machine.
According to the present invention, the carbon components in the waste coke 9 and powdered carbon are polymerized to form a long chain polymer compound having a higher briquette or pellet strength 11 than previously. Oxides of carbon are known to hydrolyze in water. This reaction results in the presence of free carboxyl radicals in the mixture. The addition of methyl ethyl ketone facilitates coupling to the free carbon ions by polymer-water ion exchange so that the styrene polymers 4 are dissolved.
In the next phase, polyvinyl acetate 6a is added to the carbon sludge. Again, the presence of the catalytic methyl ethyl ketone causes the styrene 4 to react with the polyvinyl acetate 6a. It is understood that an exothermic reaction occurs at a temperature of 8-9 ° C (15 ° F) during the briquetting of 8, with an increase in ambient temperature.
The resulting solid fuel 11, briquettes and / or pellets, is structurally stable and does not crumble during storage or handling. The solid fuel product has a reliable internal cohesiveness and high calorific value for both industrial and domestic use, and does not release solid pollutants into the environment because it burns cleanly.
Third example:
In accordance with the block diagram of Fig. 2, an equal amount of fly powder 12 and blast furnace slurry 13, possibly flakes 22, are mixed with hydrochloric acid 14 and water 15. Flywheel 12 and blast furnace slurry 13 are present in this mixture at 39% by weight, excluding water 15. This ratio was arbitrarily chosen. Hydrochloric acid 14 is added at a concentration of 4% and an appropriate amount of water 15, usually 8% by weight, is added. This initial mixture is stirred several times for ten minutes. The hydrochloric acid (14) is adjusted to facilitate the desired mixing of the waste material (16) with the pH of the mixture to give a solid fuel 17 which is not prone to disintegration.
Add s% coke 9 to the masterbatch and stir for an additional two minutes until the coke 9 is evenly distributed. While high-strength fuel 17 is not essential for household and similar applications, coke mill 9 acts as a curing agent to hold the final product together, allowing the fuel 17 to be used as a high-temperature source in blast furnaces. For uses other than blast furnaces, the coke grate 9 may be replaced by 1 carbon powder.
Thereafter, 3% by weight of conditioner 18 is added to the twice-stirred mixture to bind the acrylonitrile polymer in the mixture and stir for an additional five minutes. Methylethyl ketone is mixed with acrylonitrile as a solvent to prevent premature freezing and also to act as a clearing agent. Then 5% by weight 19 homopolymers were added and the mixture was stirred for another 5 minutes. The homopolymer 19, together with the acrylonitrile, facilitates the blending of carbonaceous materials into a non-crumbling solid fuel 17.
After continuous mixing of the obtained briquette raw material 20, it is conventionally added to a briquetting machine 21 where it is compressed into briquettes.
The strength of the briquettes does not deteriorate over time and burns cleanly in stoves, stoves, blast furnaces.
The amount of water added to the mixture may be varied depending upon the moisture content of the ingredients in the mixture. While this and other examples illustrate a mixture of recycled materials, it should be recognized that any of the waste materials can be used on their own or can be used with other carbonaceous waste materials in the form of high calorific, environmentally friendly and disintegrating briquettes, or similar. materials.
Our preferred homopolymer material, 32,024 homopolymer polyvinyl acetate emulsion, is available from National Starch and Adhesive. The conditioner used herein is an acrylonitrile polymer which is kept in a liquid state for a long time with methyl ethyl ketone. Acrylonitrile polymer is available from Polimerland and Ballard Medical Products. The use of industrial grade methyl ethyl ketone produced by Dice Chemical Co. and Thatcher Chemical Co. is recommended. 90 % methylethyl ketone and 10% acrylonitrile polymer are suitable, although these amounts are variable.
The invention may be practiced in other ways without departing from the claims, that is, the examples illustrated are exemplary and non-limiting.
