Patent number: 10138378Abstract: A method and apparatus for making carbon black having increased surface area, reduced grit and/or reduced extract levels. A plasma gas is flowed into a plasma forming region to form a plasma. The plasma then flows through a throat region which is narrower than the plasma forming section, which is connected to a separate carbon black forming region. This causes the plasma to accelerate and become turbulent prior to the exit point in the throat region. The carbon black forming feedstock is injected into the turbulence created by the throat region at a point above, at or near the exit point, resulting in the formation of a carbon black in the separate carbon black forming region. The throat region and/or injector region can be cooled, e.g., water plasma gas cooled.Type: GrantFiled: January 21, 2015Date of Patent: November 27, 2018Assignee: MONOLITH MATERIALS, INC.Inventors: Alexander F. Hoermman, Roscoe W. Taylor, Nils Severin Myklebust

Patent number: 10100200Abstract: A method of making carbon black. A method of making carbon black is described including combusting feedstock with plasma in an apparatus having a series of unit operations with individual capacities. The individual capacities of the unit operations are substantially balanced by replacing at least part of the feedstock with a feedstock having a molecular weight heavier than methane. This results, among other things, in increased utilization of the individual capacities of the unit operations and increased overall throughput.Type: GrantFiled: January 7, 2015Date of Patent: October 16, 2018Assignee: MONOLITH MATERIALS, INC.Inventors: Peter L. Johnson, Robert J. Hanson, Roscoe W. Taylor, James Premkumar

Publication number: 20180022925Abstract: Apparatus and process for the continuous production of carbon black or carbon containing compounds. The process is performed by converting a carbon containing feedstock, including generating a plasma gas with electrical energy, accelerating the plasma gas through a nozzle, whose diameter is narrowing in the direction of the plasma gas, guiding the plasma gas into a reaction area where feedstock is injected under conditions generated by aerodynamic and electromagnetic forces, including intense rapid mixing between the plasma gas and feedstock occurs. There is no significant recirculation of feedstock into the plasma chamber, and the reaction zone does not immediately come into contact with any contact surfaces. The products of reaction are cooled, and the carbon black or carbon containing compounds are separated from the other reaction products.Type: ApplicationFiled: February 1, 2016Publication date: January 25, 2018Applicant: MONOLITH MATERIALS, INC.Inventors: Ned J. HARDMAN, Roscoe W. TAYLOR, Robert J. HANSON, Peter L. JOHNSON

Publication number: 20180016441Abstract: A method of separating combustible gasses from the pores of carbon black. A method of making carbon black in a reactor is described that results in a high concentration of combustible gasses contained in the pores of the carbon black produced. The combustible gasses contained in the pores are replaced with inert gas to render the carbon black safer to process in downstream equipment.Type: ApplicationFiled: February 1, 2016Publication date: January 18, 2018Applicant: MONOLITH MATERIALS, INC.Inventors: Roscoe W. TAYLOR, Peter L. JOHNSON

Publication number: 20180015438Abstract: A method of cooling a liner in a plasma chamber. A recycle gas is contacted with or passed through the liner to cool the liner and pre-heat the recycle gas. The pre-heated gas is then recycled through the plasma chamber to become part of the plasma forming process. The method further comprises the liner is graphite, the recycle gas passes through at least one cooling channel present in the liner, at least one of the cooling channels are covered with at least one removable liner/channel cover, carbon deposits are formed from the presence of hydrocarbons in the recycle gas, at least one channel is formed in a spiral cooling channel pattern, at least one channel is formed in a substantially straight cooling channel pattern, and a plenum to aid in the production of an even distribution of cooling gas in the channels.Type: ApplicationFiled: February 1, 2016Publication date: January 18, 2018Applicant: MONOLITH MATERIALS, INC.Inventors: Roscoe W. TAYLOR, Alexander HOERMANN

Publication number: 20170058128Abstract: A high temperature heat integration method of making carbon black. A method of making carbon black is described, including reacting a carbon black forming feedstock with hydrogen gas in a plasma reactor to produce effluent gas containing carbon black and unused hydrogen, cooling the effluent gas for further processing, and recycling the unused hydrogen back into the carbon black forming process, where the unused hydrogen gas is pre-heated in a heat exchanger to a temperature up to the reaction temperature in the reactor before being recycled into the carbon black forming process. The heat exchanger for use in such process is also described.Type: ApplicationFiled: August 19, 2016Publication date: March 2, 2017Applicant: MONOLITH MATERIALS, INC.Inventors: Peter Louis JOHNSON, Roscoe W.
