Abstract
Abstract Conversion of methanol, and/or other lower aliphatic organic compounds containing at least one hetero atom, such as oxygen, sulfur, nitrogen or halogen, to higher hydrocarbons, notably hydrocarbons boiling in the gasoline boiling range, is known. The volatility of this synthetic, high octane gasoline are improved by admixing low octane natural gas liquids therewith, perhaps accompanied by addition to said admixture of n-butane as well.
