Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.
The Kværner process or the Kværner carbon black and hydrogen process (CB&H) is a method of producing carbon black and hydrogen gas from hydrocarbons such as methane, natural gas and biogas with no greenhouse gas pollution. The process was developed in the 1980s by the Norwegian engineering firm Kværner, and was first commercially exploited ...
Carbon black is essentially formed out of primary carbon, but its structure is much less arranged than that of, for example, graphite. Carbon black exists in the form of discrete particles, however, during the production process its spherical particles, also called primary particles, cluster (aggregate) into chains or clusters.
The Kværner process or Kvaerner carbon black and hydrogen process (CB&H) [162] is a method, developed in the 1980s by a Norwegian company of the same name, for the production of hydrogen from hydrocarbons (C n H m), such as methane, natural gas and biogas.
The Wacker process or the Hoechst-Wacker process (named after the chemical companies of the same name) refers to the oxidation of ethylene to acetaldehyde in the presence of palladium(II) chloride and copper(II) chloride as the catalyst. [1]

Carbon nanocones are produced in an industrial process that decomposes hydrocarbons into carbon and hydrogen with a plasma torch having a plasma temperature above 2000 °C. . This method is often referred to as Kvaerner Carbon Black & Hydrogen Process (CBH) and it is relatively "emission-free", i.e., produces rather small amount of air pollutan
