Hans Tropsch (born October 7, 1889 in Plan (West Bohemia), † October 8, 1935 in Essen ) was a German chemist .

Life

Tropsch attended the Kaiser-Franz-Joseph-Realschule in Plan until 1907 and studied at the German Technical University in Prague and at the German University in Prague . In 1913 he received his doctorate with a thesis on new derivatives of pyridine for Dr.-Ing. After working as an assistant to Hans Leopold Meyer , he went on to work in industry in Mühlheim am Main from 1914 to 1916 . In the meeting reports of the Vienna Academy of Sciences in 1914, he was able to present his first major study. 1916-17 he worked in a dye factory in Mülheim an der Ruhr and then briefly at the Kaiser Wilhelm Institute for Coal Research, also in Mülheim. 1917-20 he worked in the Rüttgerswerk in Niederau .

From 1920-28 he was back at the Kaiser Wilhelm Institute, where he worked with director Franz Fischer and Otto Roelen , from 1923 investigated the conversion of synthesis gas (CO and H 2 ) into long-chain organic substances and until 1925 the Fischer-Tropsch synthesis (FTS) (Patent 484,337; July 25, 1925 and Patent 524,468, November 2, 1926). It was promoted by Ruhrchemie AG in competition with IG (which preferred Bergius- Pier's hydrogenation process ). ( Rudolf Schenck had independently developed a similar process in Munich from 1922–26.) After the introduction of the forced exchange economy in July 1931 (→ German banking crisis ), the AGVS was used on an industrial scale from 1933 onwards. Tropsch and Hans Schrader were department heads. Kurt Peters was his successor here in 1928 .

In 1928 he accepted a call to Prague, where he was to set up and head a new coal research institute. Around 1930 he completed his habilitation in the chemistry of fuels at the German Technical University in Prague.

In 1931 he went to the USA and worked at Universal Oil Products and the Armor Institute of Technology in Chicago. Due to illness, he returned to Germany in 1935, where he died shortly afterwards in a hospital in Essen.
