Amongst other leaders that worked on this subject, Heinrich Koppers introduced the coke oven process into the US industry in 1907. Establishing Heinric Koppers AG in 1904, he created the socalled 'half direct' process for recovery tar and ammonia from coke oven gas. By 1923, 90 % of all coke oven plants in the Ruhr district used this process.
