DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to the production of carbon black in a pure form based on natural gas or methane.
BACKGROUND OF THE INVENTION
Decomposition of hydrocarbons for the production of carbon black is a well known process and there are a number of methods in existence for this purpose. The production of carbon black on the basis of methane is also described in Norwegian patent application No. 91 4904 by the same applicant. In the method which is described in this application, it has been shown that it is possible to decompose hydrocarbons in such a way that the physical properties of the carbon black to a great extent can be predetermined on the basis of given process parameters.
This has proved to be an extremely valuable possibility which can open the way for wider areas of application and for the achievement of better quality for products in which carbon black is already in use as the basic material.
From GB 1 492 346, GB 1 400 266 and DD 292 920 are known methods and processes for the production of carbon black by the pyrolytic decomposition of a hydrocarbon stock in a plasma reactor. The produced carbon black may be used in the rubber, electrical, paint and printing industries. However, the use is only directed to a general application of carbon black, and the application of a specific quality in order to obtain special properties for products is not disclosed.
There has been a need to find new applications for carbon black and especially for pure carbon black produced on the basis of natural gas, since the natural gas resources which have been established are very substantial. Methane is a hydrocarbon gas which exists in large quantities, is reasonably priced and has been shown to be well suited as a stock material for the production of pure carbon black and hydrogen. It seems that insufficient attention has been paid to the possibility and the significance of the use of pure carbon black as the basic material for final products.
SUMMARY OF THE INVENTION
Thus the object of the present invention is to provide new methods for the application of pure carbon black. A further object of the invention is to provide opportunities for the application of these materials in the form of basic materials which are both financially favourable and also afford improved quality.
These objects are achieved by the application of pure carbon black which is produced by the decomposition of natural gas or methane into their basic elements for the production of admixtures for the rubber industry, as pigments and printer's ink, for battery production, as a reduction material in the metallurgical industry, as an anode material in aluminium production, a carburizing material for the steel industry, activated charcoal, etc.
The surprising fact has been demonstrated that on the basis of natural gas or methane which are decomposed into their basic elements, viz. carbon black and hydrogen, carbonaceous materials in particular can be obtained in which the properties of the carbon, i.e. its specific weight, particle size, surface, characteristics, porosity and structure can be preset before production in such a manner that the end product obtained is specially suited to the particular above-mentioned purposes. The use of natural gas as a starting material provides a reasonably priced carbon black with special properties for special purposes and it has been shown that by means of the special application according to the invention, electrodes, admixtures, etc. are obtained with particularly favourable properties, as, e.g., in the aluminium industry or in the metallurgical industry, and a far more pollution-free production process is obtained. In the production of activated charcoal it has been shown that by means of the invention a material can be obtained with substantially better adsorption properties than with the activated charcoal used hereto, based on traditional raw materials such as wood, pit coal, lignite, peat, coconut shells, etc. In this process it is also possible to control the activated char
