Siemens Energy and Clariant, a world leader in specialty chemicals, signed an agreement to cooperate in the commercialization of a new, jointly developed sour gas shift (SGS) technology for coal gasification. The agreement appoints Clariant as the exclusive catalyst supplier for all projects where Siemens offers sour gas shift ("SGS") systems. While the collaboration covers all global projects, commercialization will focus on China – the region with the highest growth rate of coal-to-chemical projects. Stefan Heuser, Head of the Catalysts Business Unit at Clariant, stated: "This global cooperation is a very important step in marketing our innovative catalysts for coal-to-chemical applications.
