History of Science and Engineering Annotation << Back Innovative Technical Solutions of Azerbaijani Oil Workers During the Great Patriotic War. Inventions for the Sake of Victory Huseynov A.A. The article is devoted to the study of the scientific activities of Azerbaijani petrochemical scientists, engineers (including Yu. Mamedaliyev and M. Abdullayev) and technical specialists in the development of innovative technical solutions in the period 1941–1945. The main attention is paid to the developments that played an important role in providing the Red Army with fuel. The work, based on archival materials, examines an exhaustive list of key breakthrough technologies and engineering solutions that made it possible to increase the production of petroleum products, expand their range, improve quality, and improve the production base of Baku oil refi neries. In particular, information is provided on the methods of oil transportation across the Caspian Sea, the development of high-octane grades of aviation gasoline, and thermal cracking and pyrolysis technologies. Based on archival materials, the existing key problems of the oil industry and proposals for overcoming them are identified. Keywords: Baku, Azerbaijani oil refi neries, cracking, pyrolysis, reconstruction, innovations, gasoline, fuel. DOI: 10.25791/intstg.3.2025.1532 Pp. 03-11.
