Gasoline composition
Abstract
Abstract A MOTOR FUEL COMPRISING 1-40 VOLUME PERCENT OXYLATE AND 99-60 VOLUME PERCENT ALKYLATE. THE OXYLATE CONSISTS OF TERTIARY BUTYL ALCOHOL, ISOPROPYL ALCOHOL, AND METHYL ALCOHOL. PREFERRED COMPOSITION FOR THE OXYLATE IS ABOUT 20-90 VOLUME PERCENT TERTIARY BUTYL ALCOHOL, 5-40 VOLUME PERCENT ISOPROPYL ALCOHOL, AND 5-40 VOLUME PERCENT METHYL ALCOHOL. THE ALKYLATE USED IN THE MOTOR FUEL COMPOSITION CAN BE OBTAINED, FOR EXAMPLE, FROM SULFURIC OR HYDROFLUORIC ACID ALKYLATION. THE OXYLATE IMPROVES THE OCTANE OF THE ALKYLATE GASOLINE MORE THAN EXPECTED, AND ALSO THE OXYLATE HAS AN UNEXPECTEDLY HIGH BLENDING OCTANE NUMBER IN THE ALKYLATE OVER A WIDE RANGE OF PERCENTAGE AMOUNTS OF OXYLATE IN THE ALKYLATE.
