CATALYSIS IN PETROLEUM REFINING INDUSTRY

Abstract

The deep processing of heavy oil increases the production of hydrocarbon gases. The resulting butanes do not always find an equivalent market. A mixture of oxygenates with a high octane number is obtained in this work via oxidation of industrial isobutane fraction. The reaction proceeds both in with and without using Au/Silicalite-1 and Cu/SiO2 as catalysts. The influence of factors that reduce the formation of undesirable impurities (hydroperoxides, peroxides, and acids) is studied. Tert-butyl alcohol (TBA) obtainable with a selectivity of 64–69% and butane conversion of 55–69% is a target product. TBA has a RON of 113. Alcohols and ketones having RONs within 106–115 appear together with TBA during the oxidation. The best result was obtained for a Cu/SiO2 catalyst. More than 18% of TBA and 2.9 times more ketones are removed from a unit volume of a reaction space in the presence of a catalyst than during oxidation without a catalyst. The total productivity of the products suitable as high-octane components is 40 g/(L h), while the RON of this mixture is ≈111. A mixture of oxygenates including TBA has a lower volatility than that of methyl tert-butyl ether, which is especially important for the stability of gasolines in summer.
