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.
Since the year 2012, CHOREN Industrietechnik GmbH has continued the business sector 'CCG® Coal Gasification' of the former CHOREN Industries GmbH.
The extensive know-how regarding CCG® coal gasification continues to be further developed by specialists who were taken over by CHOREN Industries GmbH and other companies.
CHOREN Industrietechnik GmbH is the only company in the world which possesses the know-how and all associated patent and brand rights of CHOREN Industries GmbH relating to the CCG® coal-gasification process, and which can offer corresponding licenses and engineering-technical performances for the CCG® coal-gasification process.
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.
This is the base material for the manufacture of classical synthesis gas products, such as methanol and ammonia, and is used for the manufacture of fuels and a great number of chemical base materials, or can be used for electric power and heat generation.
As a result of the application of the innovative burner concept for the dry coal-dust gasification, as well as the subsequent water-quench, the following advantages result for the process:
- High quality of the synthesis gas: No aromatics, tars, phenols and condensates
- High raw material variability: Hard coal, lignite, petroleum coke, mixtures of waste and/or biomass
- The employment of inferior coal qualities with high ash content is possible
- Low capital expenditure due to compact design and optimized water-quenching
- Low operating costs
- High flexibility through fast startup and shutdown
- High level of plant availability through simple and rugged design
