CHOREN’s

Roots: Low Grade Coal Gasification

After German Reunification former DBI know-how employees accumulate around Dr. Bodo

Wolf including leading engineering competence of gas conglomerate ‘Schwarze

Pumpe’

(GSP)

Research targets the improvement in development of the GSP gasifier for sludge and organic waste drying

R&D work leads to improved coal gasification system and development of proprietary Carbo-V®

biomass gasification system

Component manufacturing for 3rd

parties (e.g. vessel and component fabrication for Sustec/Future Energy, today SIEMENS)

2007 First CCG project in China, 2*400 MW coal gasifiers for repowering project in Ammonia facility commissioning in 2010
