TH8170B - Systems for producing carbon black - Google Patents

Abstract

Production system Carbon black and hydrogen by the decomposition of gas hydrocarbons that are involved in thermally decomposition reactions (1) with the active part (2) are connected with temperature-adjustable regions to allow Influence and regulate properties of carbon black, including Adjust the skin and structure of carbon black too. Reaction section with gas feeding device And materials in different temperature regions following the reaction part (2) are used for cooling (3) for the reaction products. This may pre-heat the feed gas and the gas plasma (19) and which is connected by a separation device. It is preferable to have a cyclone (4,5) for separating coarse particles from carbon. The cyclone component (4,5) is attached to a filter device (7) that filters the carbon black with the required particle size and structure. To the silo (8) and continue the process. The system has a pipeline for delivering part of the hydrogen to the chemical industry, carrying energy, as well as back to the reaction part (2) via the return tube.
