CHOREN Industrietechnik GmbH
The CCG® technology is based on a long-standing, proven process of coal gasification for the generation of an ultra-pure, high-energy synthesis gas. The Deutsche Brennstoffinstitut (German Fuel Institute) in Freiberg (DBI) began as early as the 1970's with the development of the entrained-bed gasification of coal. As a result of a widely-based process trial, a 3 MW pilot system was built in Freiberg in 1979. Test coals came from Germany, China, Russia, South Africa, Spain, Australia and the former Czechoslovakia.
Building on the knowledge acquired from the operation of the pilot system, a 200 MW entrained-bed gasification system was finally constructed by Gaskombinat "Schwarze Pumpe" (GSP) for the gasification of 720 t/d dry coal, which already indicated a cooling screen for the protection of the gasification reactor. Intensive research and development work on the GSP process led to an efficient coal gasification system for elutriates and organic waste, and to an independent Carbo-V biomass gasification process.
After the reunion of Germany, Dr. Wolf, a visionary in the sector of sustainable-energy generation, and some remaining employees of DBI and GSP, founded the company Umwelt- und Energietechnik Freiberg (UET), later CHOREN Industries GmbH, in order to continue the research and development work in biomass gasification (CARBO-V) and coal gasification (CCG®).
In the year 2003 the first test operation in the world of a continuously-working BtL system took place. On this basis, the planning work on a project CCG® for Yankuang/China began in 2007. In the years following, planning documents and significant core components were supplied by CHOREN to Yankuang. As well as this, UET and CHOREN in the 1990's developed the technology for the steam-fluidized-bed drying of coal and elutriates.
