Abstract (en)
A novel gasoline additive is described comprising a mixture of methanol, iso-propanol, methyl t-butyl ether and, optionally, a C5- isomerate, typically in amounts of, per 100 parts by weight of additive, from about 5 to about 90 parts by weight methanol, from about 3 to about 35 parts by weight iso-propanol, from about 3 to about 35 parts by weight mthyl t-butyl ether, and from 0 to 35 parts by weight of C5- isomerate. A process is described for producing such an additive from natural gas streams by isomerising n-butane component thereof to iso-butane, dehydrogenating propane component of the natural gas stream to propylene and iso-butane formed by isomeration of n-butane to iso-butene respectively, converting resulting propylene to iso-propanol, etherifying resulting iso-butene with methanol to form methyl t-butyl ether, and blending resulting iso-propanol and methyl t-butyl ether with methanol, and optionally with a C5- isomerate formed by isomerising C5 and heavier hydrocarbons present in the natural gas stream, to form the additive.
