摘要:
In a system for the production of carbon black and hydrogen by the decomposition of hydrocarbon gas, there is in connection with the thermal decomposition reactor (1) provided a reactor (2) with adjustable temperature zones in order to influence and control the properties of the carbon black as well as to modify the surface and structure of the carbon black. The reactor has means for supplying gases and materials in the various temperature zones. Downstream of the reactor (2) there is provided a cooler (3) for the reactions products, in which feed gas and plasma gas can be preheated (19) and which is followed by separation means which may preferably consist of a cyclone (4, 5) for separating coarse particles from the carbon component. The cyclone (4, 5) is connected to a filter device (7) wherein carbon black of the desired particle size and structure is filtered out to a silo (8) and further processing. The system is equipped with a pipe for transfer of hydrogen partly to the chemical process industry, as an energy carrier, as well as back to the reactor (2) via a return pipe.

The hot raw effluent gas stream from a free-flow partial oxidation gas generator is split into two hot raw gas streams which are separately processed. One split gas stream is cleaned by quenching and scrubbing with water. Entrained particulate carbon is removed therefrom as a carbon-water dispersion from which it is extracted with a liquid organic extractant. The resulting liquid organic extractant-carbon-water dispersion is vaporized using the sensible heat from the other split gas stream. Particulate carbon is then removed from the other split gas stream by scrubbing with a liquid hydrocarbon fuel to separate out a liquid hydrocarbon fuel-carbon dispersion which may be supplied to the gas generator as a portion of the feed. The remaining gaseous mixture is cooled and separated into a clean dewatered product gas stream, water, and liquid organic extractant. The latter two materials are recycled,

摘要:
In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. In the area immediately below the plasma flame a mixing of the hydrocarbon material and the plasma gas occurs, the temperature being increased to decomposition temperature for the raw material. In this area free hydrogen and dehydrogenated carbon material are produced in the form of drops of liquid. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.
