[2] Construction of the complex of catalytic cracking units was launched in Baku by the decision of the Ministry of Oil Industry of the USSR in the former Soviet Union.

The order was issued on the establishment of the New Baku Refinery by the Ministry of Oil Industry of the USSR on date July 29, 1953.

At the time, there was a shortage of high-quality gasoline in the Soviet Union, and it was natural to build the refinery in Baku, close to oil deposits.

In order to meet requirements of international standards of oil, the project was organized on cleaning the fuel with alkali and production of crude naphthenic acid in this unit under the license of “Merichem” company (USA).

Catalytic cracking device for the production of high octane gasoline components was built and put in service in 1993.

Besides the catalytic reforming unit exploited in 1980, it helps to increase the quality of produced diesel fuel and gasoline.

In honour of the 50th anniversary of "Azerneftyanajag" Oil Refinery and its achievements in production, it was renamed after Heydar Aliyev, the leader of Azerbaijan on April 22, 2004.
