Design of reforming catalysts: Development of new technologies for the manufacture of motor fuels on this basis

Abstract

The results of studies on the state of platinum in alumina-platinum reforming catalysts performed at the Institute of Hydrocarbon Processing, Siberian Branch of the Russian Academy of Sciences, in the past 20 years are summarized. The main result is the determination of the important role of the nonmetallic states of platinum (Ptσ) in adsorption and catalysis. The main principles of the development of highly efficient catalysts and technologies for their manufacture are formulated. Data on the industrial applications of new reforming catalysts at seven commercial reforming plants under conditions of reforming gasoline production (about 3 million tons per year) with research octane numbers of 96–100 are given. The applicability of new catalysts to the combined conversion of C3–C4 and C5+ alkane mixtures into high-octane motor fuel components is demonstrated. The results of the development of three modifications of a new technology for the manufacture of environmentally safe high-octane gasoline with the selectivity of formation of the target product close to 100% are presented.
