| Summary: | The objective of this study was the development of catalysts for catalytic liquid-phase hydrogenation of gasoline fractions of Atyrau Refinery LLP at elevated hydrogen pressure. The selective efficient catalysts on the basis of the platinum metals applied on various carriers are synthesized. The hydrogenation of two gasoline fractions Stable catalysate LH (0.37% benzene), straight-run gasoline AVT (3.18% benzene) was studied. After the catalytic hydrogenation the benzene is absent, the content of aromatic compounds is reduced from 55.12% to 32.5 (wt.). The content of olefins is reduced from 0.23 to 0.11% (wt.) and paraffins content is decreased from 12.41 to 11.99% (wt.), but the amount of isoparaffins increased from 30.08 to 34.09% (wt), naphthene content increased from 2.12 to 10.14% (wt). Octane numbers of petrol fractions after hydrogenation were practically unchanged, while the benzene content decreased from 3.18% (initial sample) to the total absence in the samples. |
