Abstract:
1. A process for preparing at least two compositions suitable for production of gasolines, which process comprises: fractionating an alkylation product to produce a first cut boiling in the range 90-106° C., a second cut boiling at temperature lower than said first cut, and a third cut boiling at a temperature above said first cut, blending at least 2% (by volume of the total composition) of said first cut with a at least 5% of a component selected from at least one of a paraffin, an aromatic hydrocarbon and an olefinic hydrocarbon, said component having a b.p. 60-160° C., to produce a first high octane unleaded gasoline composition of RON at least 97 and MON value at least 86 with not more than 5% of the total composition of hydrocarbon of b.p. more than 160° C. and less than 5% of 2,2,3-trimethylbutane or 2,2,3-trimethylpentane, and incorporating said second and third cuts with said component to produce a second high octane unleaded gasoline composition of Research Octane Number (RON) at least 92 and Motor Octane Number (MON) value at least 80.
