Process for obtaining alkylation gasoline through the use of refinery blends and organic acids

A process for production of alkylate gasoline using a refinery mixture containing olefins and iso-paraffins, said process comprising:

• (a) adding an organic acid catalyst comprising methanesulfonic acid at 99% purity in amounts ranging from 10 to 50 weight % respective to the mass of the refinery mixture and the organic acid, to a batch reactor provided with a Teflon lining and a propeller;
• (b) sealing and cooling the reactor to −5° C.;
• (c) adding the refinery mixture containing olefins and iso-paraffins, by the employment of micrometric valves;
• (d) connecting the reactor to a heating device and heating at a rate of 5° C./minute up to a temperature within a range of 0 to 140° C.;
• (e) injecting nitrogen to pressures within a range of 2 to 6 MPa and, at the same time, stirring the reaction at 1500 rpm using the propeller for reaction times from 5 to 30 minutes;
• (f) shutting off heating and stirring;
• (g) stabilizing the product mixture to ambient temperature;
• (h) taking a gas sample by using a gas collector plastic bag;
• (i) afterwards, cooling down the reactor to −5° C.;
• (j) extracting a liquid product comprising alkylate gasoline at −5° C. and a solid used catalyst;
• (k) neutralizing the liquid product comprising alkylate gasoline with a saturated solution of sodium bicarbonate at ambient temperature;
• and
• (l) recycling the solid used catalyst in consecutive production of alkylate gasoline according to steps (a)-(k).
