Abstract

In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the substance is fed through a plasma torch. which causes thermal decomposition of the feed substance. Move the feed through the plasma torch (A) in the cool inlet (1) and proceed to heating first in the region next to the plasma flame in the region following the rear of the flame. plasma lights Mixture of hydrocarbons and plasma gases occurs. causing the temperature to rise to the temperature of the decomposition of raw materials. In the region where free hydrogen and dehycrylenetec carbon is formed in the form of liquid droplets. Through this formation, one or more subsequent steps undergo the final and complete decomposition of hydrocarbons to black carbon and hydrogen in this area may be added further. which causes suspension and reaction with the carbon black has already occurred. This allows for an increase in particle size, density and volume produced without additional energy supply. which after Dispose of manufactured products and separate them. and possibly transfer the hot gas in the pipe back to the torch. to further increase the productivity of additional energy

Claims (4)

1.Method for the decomposition of hydrocarbons to produce hydrogen and carbon black, which is fed through a plasma torch. Which causes the thermal decomposition of the feed substance And where the reaction takes place in the reaction area The characterization that the feeder should use methane to pass through the plasma torch. In the temperature-controlled inlet pipe so that it is below 1000C it should be lower than 650-700C when it leaves the inlet. The feeder is first approximately uniformly heated in the region adjacent to the plasma flame region. Feed this feed substance in the middle relative to the flame of the plasma torch so that the plasma flame surrounds the feeder. In the next area behind the plasma flame A mixture of hydrocarbons and plasma gas has been formed, where hydrogen should be used and which should be recycled, the temperature rises to exceed 1600 C, which is the decomposition temperature of the raw material. And where free hydrogen and dehydrogenetic carbon in the form of liquid droplets arise in this area where the resulting substance passes through one or more of the subsequent stages. It maintains a temperature between 1200C and 1600C and performs the final and complete decomposition of hydrocarbons to carbon blacks and hydrogen. That may add additional ingredients further in this area Which caused the suspension And react with the carbon black frog that has already been produced Which causes an increase in particle size Densities and volumes produced without the use of energy. Which afterwards Discharge the resulting product and separate. And that may transfer the hot gas in the pipe to flow back to the torch in order to further increase the production of energy and temperature in the controlled reaction region. By adjusting the feed velocity for the reagent and the plasma gas. And / or by controlling the power of the plasma torch and / or by modulating the reaction site fire pressure. This makes it possible to control the quality of the carbon black that is made to achieve the desired quality. 2. Method according to Clause 1 that describes the characteristics that In the final step of the method, an additional plasma torch is used to control the temperature. 3. Method according to claim 1 or 2 that characterizes the nature of no other material. Especially materials that cause spoilage Included in decomposition products In addition to materials that are already present in the feed 4. Equipment for use in the determination of claim 1 for effective hydrocarbon decomposition. It consists of a plasma torch (A) and a reaction channel (B) that characterizes that This plasma torch (A) consists of an inlet pipe (1) in the center. At least three electrodes (2,3,4) and at the end of the reactor (B) are attached to the inside of the reaction channel (B ), Carbon-lined, with inlet openings (8) in the side wall area for additional feed agents and at the end of the reactive channel opposite the plasma torch, there is an outlet for the end product, and it may also be possible to have Recirculation tube for manufactured gas Normally hydrogen Which leads to the plasma torch (A)
