An unleaded gasoline composition comprises, based on the total volume of the unleaded gasoline composition, 50 to 96 vol. % of an unleaded gasoline; 2 to 20 vol. % of a mixed butanol; and 2 to 30 vol. % of a distillate oil fraction comprising a paraffin, an olefin, a naphthene, and an aromatic at an initial boiling point cut of 180&#xb0; C., wherein the unleaded gasoline, the mixed butanol, and the distillate oil fraction are selected to provide the unleaded gasoline composition with a Research Octane Number of 90 to 101, determined in accordance with ASTM D 2699; and a Motor Octane Number of 81.4 to 90, determined in accordance with ASTM D 2700.

Lead-free gasoline blend

An octane-enhancing additive includes a mixed butanol composition, sec-butyl ether, methanol, methyl tert-butyl ether, and a C4-dimer, the mixed butanol composition comprising sec-butanol and tert-butanol, and the C4-dimer comprising di-isobutylene, 2,2,4 trimethylpentane, 2,3,3 trimethylpentane, or a combination comprising at least one of the foregoing.

Alcohol and ether fuel additives for lead-free gasoline

A method of purifying alcohol produced in a process that includes the Oxo process is disclosed. Aldehyde from the Oxo process that remains with the alcohol is removed by a reaction with an alkali sulphite to produce an insoluble adduct and alcohol having a reduced amount of aldehyde mixed with it. The adduct is removed from the alcohol by filtration.

Process for aldehyde removal from alcohols by treatment with bisulphite

A method of recovering 2-ethyl hexanol (2-EH) from crude alcohol that includes the 2-ethyl hexanol, 2-ethyl, 3-propyl acrolein (EPA), and 2-ethylhexanal (EHA) is disclosed. The crude alcohol stream is first separated into a first stream of primarily 2-EH, a second stream of primarily EPA and 2-EH collectively, and a third stream of primarily 2-EH and EHA collectively. The second stream and the third stream are combined to form a combined stream. The combined stream is processed further to form a first product stream comprising primarily 2-EH and a second product stream comprising primarily, 2-EH, EHA, and EPA collectively.

Recovery of ethyl hexanol from recycle streams in 2-ethyl hexanol process

A process for preparing a gasoline octane boosting composition, including contacting a pyrolysis oil with a non-thermal oxygen plasma to produce an oxidized pyrolysis oil; and mixing the oxidized pyrolysis oil with a gasoline additive to produce the gasoline octane boosting composition. The gasoline octane boosting composition can be used in a gasoline blend.
