Leaving Leipzig, Bosch worked for BASF AG, of which (when it became part of the cartel IG Farben) he was later president; and here he succeeded in transferring from laboratory to industrial scale Fritz Haber's process for synthesizing ammonia from its elements, hydrogen and nitrogen, catalytically at high pressures. Research on this process involved the carrying out of more than 20,000 experiments, including an exhaustive search for catalysts among the metals and their compounds. The Haber-Bosch process became the main industrial procedure for nitrogen fixation. He also invented the Bosch process for preparing hydrogen on a manufacturing
scale by passing a mixture of steam and water gas over a suitable catalyst
at high temperature. |
