| titleOfInvention | Method for isomerisation of light gasoline fractions containing c7-c8 paraffin hydrocarbons |
| abstract | FIELD: chemistry. ^ SUBSTANCE: invention relates to a method for isomerisation of light gasoline fractions containing C7-C8 paraffin hydrocarbons by extracting the C7-C8 fraction from wide gasoline fractions and bringing said C7-C8 fraction into contact with a catalyst containing a hydrogenating-dehydrogenating component on an oxide support in a hydrogen medium at high temperature and pressure in two reactors, fractionation to obtain a product fraction and a fraction of n-paraffins, monomethyl-substituted paraffins and methylcyclohexane which is recirculated into the gas-raw material mixture. The C7-C8 fraction (raw material) is extracted such that its content of C5-C6 hydrocarbons is equal to 0.1-15 wt %, while that of C8 hydrocarbons is equal to 0.1-20 wt %, by mixing the extracted C7-C8 fraction with hydrogen in molar ratio hydrogen: raw material equal to 0.5-4, with formation of a gas-raw material mixture and feeding said mixture into the first of two series-connected isomerisation reactors at temperature 160-250C, pressure 1.0-4.0 MPa, and bulk speed for feeding material equal to 1-5 h-1. Quenched hydrogen at 40-60C is fed into the second reactor, with molar ratio hydrogen: raw material equal to (0.1-1.0):1, and the oxide support is a composition of metal oxides: aAI2O3bZrO2cWO3dTiO2eMnO2, where weight ratios of the oxides are as follows: a=0.04-0.30; b=0.60-0.90; c=0.05-0.15; d=0.001-0.10; e=0.001-0.01. ^ EFFECT: obtaining isomerisate with high octane number. ^ 2 cl, 3 tbl, 17 ex |
