Gerhard Öhlmann

Gerhard Öhlmann

Gerhard Öhlmann (born December 31, 1931 in Neuhaldensleben ) is a German chemist and academy professor . As a chemist, Öhlmann dealt with physical chemistry , especially catalysis research and kinetics .

Career

Gerhard Öhlmann was born in Neuhaldensleben , which was merged with Althaldensleben in 1938 to form the town of Haldensleben near Magdeburg in what is now Saxony-Anhalt . He is the son of the waiter and innkeeper Erich Öhlmann and his wife, the trimmers Marianne Öhlmann , geb. Becker . His siblings are the older sister Margot (1927–1998) and the younger brother Lothar (* 1940; doctor). From 1938 to 1941 he attended primary school, first in Neuhaldensleben and then in Börgitz , Gardelegen district , the middle school in Stendal and the high school in Haldensleben , which he graduated from high school in 1950 .

Immediately after high school studied Öhlmann 1950-1951 chemistry at the Martin Luther University in Halle (Saale) . His chemistry studies, he led from 1951 to 1956 at the Zhdanov University in what was then Leningrad in the Soviet Union , now Saint Petersburg in Russia continues, graduating with a degree in chemistry . His diploma thesis "Interaction of some beta-monoalkyl-substituted glycidic acids with aniline" was written under the guidance of the doctoral lecturer WF Martynow .

Öhlmann has been married to the chemist Marina Nikolajewna Selenina since 1956 , the couple has an adult daughter Katharina (* 1958), who works as an advertising economist and fashion designer.

Chemist

He began his professional activity in August 1956 in Leipzig at the "Institute for Organic-Chemical Industry" in Permoser Strasse, which was then under the direction of the professor and later rector in Merseburg Eberhard Leibnitz . As early as February 20, 1957, however, he switched to an apprenticeship at the Zhdanov State University in Leningrad. The topic of his dissertation was: "Interaction of aliphatic and aromatic glycidic esters with ammonia and aniline". The reviewers were Professor TI Temnikowa and WF Martynow , who had already advised him on his thesis. The Russian degree obtained was “Candidate in Chemical Sciences”, equivalent to “Dr. rer. nat. ”at German universities.

From July 1957 to May 1960, Öhlmann was "working group leader" in the Leipzig institutes of the German Academy of Sciences in Berlin (DAW) and then until May 1962 at the DAW Institute for Measurement and Testing Technology in Berlin . Together with other institutes, this original “Institute for Organic-Chemical Industry” was transferred from the Ministry of Chemical Industry to the DAW in the second half of the 1950s.

From mid-1962 to the end of 1973, Öhlmann was head of the “Kinetics” department at the “Institute for Physical Chemistry” at DAW in Berlin. During this time he also obtained his habilitation in 1969 at the Humboldt University of Berlin , chemistry section (section director: Hans-Georg Henning ) with the habilitation thesis "Kinetics and Mechanism of Gas Phase Oxidation of Saturated Hydrocarbons of Medium Chain Length (C7-C8)". The reviewers were Professors Wolfgang Schirmer and Günter Hilgetag .

In the course of the beginning reform of the academy, which was carried out from 1968 to 1972, the Central Institute for Physical Chemistry (ZIPC) was established in Berlin in May 1968 , including the “Institute for Inorganic Catalysis Research” and the “Institute for Structural Research” as well as the “Institute for scientific device engineering ".

In 1970 Öhlmann was appointed professor at the German Academy of Sciences in Berlin (DAW), which was renamed the Academy of Sciences of the GDR (AdW) when the academy was reformed in 1972 . In 1972 he was also elected as a "corresponding member" of the learned society of the AdW of the GDR.

From the beginning of 1974 to the end of 1985, Öhlmann was the director of the "Catalysis Kinetics" division of the ZIPC of the AdW and was also the deputy director of the Central Institute for Physical Chemistry (ZIPC) . In 1974 he was elected as a "full member" of the learned society of the AdW.

From the beginning of 1986 to June 1990, Öhlmann was director of the ZIPC , succeeding Wolfgang Schirmer , after which he resigned from the position of director and was handed over to his successor Lutz Zülicke . From July 1990 to the end of May 1991, Öhlmann was head of the “Multi-Component Catalysts” department in the catalysis division at ZIPC. In the course of the liquidation of the AdW of the GDR, Öhlmann left the ZIPC and the learned society in June 1991; his transition to early retirement took place.

Business consultant

After German reunification , Öhlmann was a scientific advisor in the research department of the "United Aluminum Works" (VAW) in Bonn , and later from 1995 - after zeolite research was separated from the VAW - scientific advisor in the independent company "Alsi-Penta Zeolithe GmbH" in Schwandorf .

In 1993 and 1994 Öhlmann made several stays in "Savannah" ( USA ) as a consultant to the company "Intercat - Savannah, INC."

From 1995 to 1997, Öhlmann carried out consulting and experimental engineering activities for several months at the US company TRICAT in Bitterfeld for the development and technical implementation of a process for the production of a new sorbent based on an Al-rich molecular sieve.

At the end of 2003, Öhlmann signed a consulting contract with TRICAT Zeolithes GmbH in Bitterfeld, which was also taken over by "Südchemie AG" as "Südchemie Zeolithes GmbH" after the company was taken over. In the years 2004 to 2008, the scientific and technical conditions were worked out here in cooperation with the IBUTEC company in Weimar and the associated thermal process stages for a technology for the production of a zeolite catalyst (MTProp) were implemented.
