CarboTech AC GmbH provides a range of products which include: * [Granular Activated carbon](/source/Activated_carbon)s * [Extruded Activated Carbon](/source/Activated_carbon)s * [Powdered Activated Carbon](/source/Activated_carbon)s * [Impregnated Activated Carbon](/source/Activated_carbon)s * Pool Activated Carbons * Carbon [Molecular Sieve](/source/Molecular_Sieve)s * Mobile Adsorber Rentals ==History== The roots of CarboTech AC GmbH connect to the early 1938, when the foundation of the [bituminous coal](/source/bituminous_coal) mining society ('''Steinkohlenbergbauvereins''') has taken place. After [World War II](/source/World_War_II), the '''Bergwerksverband GmbH''' began setting up experimental facilities for the production and development of activated carbons from [bituminous coal](/source/bituminous_coal). In 1956, a large-scale pilot plant was commissioned on the site of the former Queen Elisabeth coal mine ([Zeche Königin Elisabeth](/source/%3Ade%3AZeche_K%C3%B6nigin_Elisabeth)) in [Essen](/source/Essen) and in 1958, foundation for the '''Bergbau-Forschung GmbH''' [http://www.archive.nrw.de/LAV_NRW/jsp/bestand.jsp?archivNr=421&tektId=108 Archive NRW] as the research institute of [bituminous coal](/source/bituminous_coal) mining was established. Later in the 1970s, the development of Carbon [Molecular Sieve](/source/Molecular_Sieve)s took place and this enabled the production of 99.999% pure [nitrogen](/source/nitrogen) and [hydrogen](/source/hydrogen) by Bergbau-Forschung GmbH.[http://patents.justia.com/patent/5275640 Patent, Bergwerksverband GmbH] Between the years 1972 and 1980, Bergbau-Forschung received various patents [http://patents.justia.com/assignee/bergwerksverband-gmbh Patents, Bergwerksverband GmbH] for [Pressure swing adsorption](/source/Pressure_swing_adsorption) plants for [nitrogen](/source/nitrogen) production and [hydrogen](/source/hydrogen) purification.[http://www.carbotech.de/unternehmen/?lang=en#history CarboTech History] In the year 1974, the reactivation of activated carbon using the [fluidized bed](/source/fluidized_bed) method was developed by the Bergbau-Forschung. In 1980, a procedure of the dry DeSOx/DeNOx was developed. Until 1988, the activated carbon manufacturer Bergwerksverband was a 100% subsidiary of the Bergbau-Forschung. Later the company underwent several changes and expansions in the product range which include [Powdered Activated Carbon](/source/Activated_carbon)s and [Impregnated Activated Carbon](/source/Activated_carbon)s. Between the years 2001 and 2004, CarboTech Aktivkohlen GmbH had spin-off to Rütgers Chemicals AG, Rütgers CarboTech GmbH and finally in the year 2005, the company was taken over by '''International Chemical Investors Group'''.[http://www.ic-investors.com/news/details/article/international-chemical-investors-to-acquire-five-ruetgers-chemicals-businesses.html IC-Investors News, June 2005] Later in the year 2006, the name of the company changed to '''CarboTech AC GmbH'''. In 2016, the heat recovery system for activation and reactivation was expanded and put into use. In 2017 the rotary kiln was also upgraded for reactivation. In 2018, the area for mobile Plug & Clean systems was expanded. In 2021, the company entered the food, beverage, cement, and automotive markets. The company site was acquired from the lease and the company property at the old production site in Castrop-Rauxel was sold. In 2023, the company expanded to become a full-service provider with an exchange service (including silo and multi-chamber vehicles), cooperation in plant engineering, grinding and packaging systems. ==Group of CarboTech Companies== The Bergbau Forschung which was established in 1958 is the root for the company. After several changes due to spin offs and after the take over from the International Chemical Investors Group, in the period between 2010 and 2013, the original company was split into CarboTech AC GmbH, CarboTech Production GmbH and CarboTech Services GmbH. ==References== {{Reflist}} Category:1958 establishments in West Germany Category:Chemical companies of Germany Category:Chemical companies established in 1958 Category:Companies based in Essen Category:Manufacturing companies of Germany --- Adapted from the Wikipedia article [CarboTech](https://en.wikipedia.org/wiki/CarboTech) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/CarboTech?action=history)).
