摘要: A method and apparatus for making carbon black. A plasma gas is flowed into a plasma forming region containing at least one, magnetically isolated, plasma torch containing at least one electrode, and forming a plasma. Collecting the plasma formed in a cooled header and flowing the plasma through at least one reaction region to heat the reaction region, and injecting carbon black forming feedstock into the reaction region, resulting in the formation of at least one grade of carbon black. An apparatus for making carbon black is also described including a plasma forming section containing at least one, magnetically isolated plasma torch containing at least one electrode, in fluid flow communication with at least one carbon black forming reactor section, the plasma section and reactor section separated by a plasma formed collection header.

摘要: 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.

摘要: The present disclosure provides, for example, systems and methods for generating carbon particles. Carbon particles may have a total content of polycyclic aromatic hydrocarbons of less than or equal to about 0.5 parts per million, a content of benzo[a]pyrene of less than or equal to about 5 parts per billion, and a water spreading pressure that is less than about 5 mJ/m2. A carbon particle among the carbon particles may comprise less than about 0.3% sulfur by weight or less than or equal to about 0.03% ash by weight.

摘要: Design advances for improving the performance of a plasma torch. The use of one or more of various advances described herein can improve the efficiency and effectiveness of the torch, the reactor and the manufacturing process. The use of the torch with hydrogen plasma gas, natural gas feedstock, and carbon black production are also described.

摘要: A method and apparatus for operating a DC plasma torch. The power supply used is at least two times the average operating voltage used, resulting in a more stable operation of the torch. The torch can include two concentric cylinder electrodes, the electrodes can be graphite, and the plasma forming gas can be hydrogen. The power supply provided also has the capability of igniting the torch at a pulse voltage of at least 20 kilovolts.

摘要: 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.
