摘要:
A two-step process for the oligomerization and hydration of a mixed butenes feed is provided and is implemented in a two-stage system. The two-step process yields a product consisting of diisobutenes (DIBs) and mixed butanols. The DIBs are produced via the selective oligomerization of isobutene in a first stage and the mixed butanols are produced via the hydration, in a second stage, of mixed butenes that remain unreacted in the first stage.
摘要:
The invention relates generally to a charcoal ignition fluid that is composed of a cellulose ether polymer, butanol, and water. The charcoal ignition fluid has performance characteristics similar to petroleum distillate but is more sustainable. Additionally, the charcoal ignition fluid can include ethanol and/or an alcohol to reduce the water content. Moreover, the charcoal ignition fluid can include an acetate salt to increase the visible flame for safety purposes. The charcoal ignition fluid may also include an organic ester to enhance the odor of the ignition fluid.
摘要:
The present invention is directed to the preparation of oxygenated, unsaturated hydrocarbon compounds, such as derivatives of furfural or hydroxymethyl furfural produced by aldol condensation with a ketone or a ketoester, as well as methods of deoxidatively reducing those compounds with hydrogen under acidic conditions to provide saturated hydrocarbons useful as fuels.
摘要:
A process for recovering ethanol obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and ethyl acetate and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. The ethanol product is recovered from the residue stream.
摘要:
The present disclosure identifies methods and compositions for modifying photoautotrophic organisms as hosts, such that the organisms efficiently produce alkanes, and in particular the use of such organisms for the commercial production of alkanes and related molecules. Other materials, methods, and compositions are also described.

摘要:
This invention relates to fuel compositions for use in combustion engines, such as for motor vehicle and aircraft usage. The fuel composition contains at least 99.5% of aromatic hydrocarbons and paraffinic hydrocarbons. The composition also preferably contains no lead, no multi-ring compound (only single ring compounds are present), less than about 15 ppm sulfur, and/or less than about 5 ppm nitrogen species. The resulting fuel is a drop-in fuel that provides clean burning with little to no engine deposit, high lubricity, high stability, and low corrosion.
