Title: Burkhard Freund: Innovator in Carbon Black Production
Introduction
Burkhard Freund is a notable inventor based in Erftstadt, Germany, with a significant contribution to the field of carbon black production. He holds a total of 9 patents, showcasing his innovative approach to materials science and engineering.
Latest Patents
Freund's latest patents include a method for producing a specific type of black with a CTAB surface area of 100 to 160 m²/g, a quartile ratio of more than 1.60, and an FP index greater than 0. This black is produced in a furnace reactor, where 60 to 90 percent by weight of the raw black material is injected into the reactor in the first third of the reaction zone. The remaining raw black material is injected upstream at another point. Additionally, the combustible is managed to ensure that 90 to 100 percent by weight evaporates upon first contact with the raw black material, and 80 to 99 percent evaporates 5 milliseconds before contact. These blacks are particularly useful in rubber mixtures. Another patent focuses on carbon black with a CTAB surface area ranging from about 10 to 35 m²/g and a DBP absorption of about 40 to 180 ml/100 g, with a D50 value of at least 340 nm. This carbon black can be produced in a furnace-black reactor from both liquid and gaseous raw materials, offering improved dispersibility and economic advantages in rubber mixtures, especially for extrusion profiles.
