RESEARCH AND SELECTION OF CATALYSTS FOR INSTALLATION PENTANE-HEXANE ISOMERIZATION
There are strict restrictions on the quality requirements of gasoline produced at refineries, currently operating pentane-hexane isomerization (PGI) plants, including PGI-434, use the foreign ATIS-21 catalyst from Axens, which has a number of disadvantages during operation. A study was conducted to find an alternative catalyst. To eliminate these disadvantages, it is proposed to use an alternative catalyst SI-2B of Russian production. The analysis is carried out and the comparative characteristics of the catalysts are presented, including a comparison of the activities in the formation of isomers. The results of the study show that replacing the ATIS-2L catalyst at the PGI-434 installation with a SI-2B catalyst will improve the conditions of the isomerization process, as well as lower capital and operating costs. The most profitable catalyst has been selected.
