The invention provides non-naturally occurring microbial organisms containing a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms selectively produce a fatty alcohol, fatty aldehyde or fatty acid of a specified length. Also provided are non-naturally occurring microbial organisms having a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms further include an acetyl-CoA pathway. In some aspects, the microbial organisms of the invention have select gene disruptions or enzyme attenuations that increase production of fatty alcohols, fatty aldehydes or fatty acids. The invention additionally provides methods of using the above microbial organisms to produce a fatty alcohol, a fatty aldehyde or a fatty acid.
摘要:
Disclosed is a preparing process of synthesizing methanol as high clean fuel using coal gasifying, power plant or other industrial waste gas and compounding absent gas itself, which comprises the following steps: introducing industrial waste gas as raw materials; processing industrial waste gas to prepare one or two product gases of O2, CO and H2; introducing product gases to synthetic tower; controlling the ratio of the gases entering synthetic tower and ensuring the gas components in synthetic tower, and automatically supplementing the absent gas in synthetic tower by computer, till the supplement obtains required ratio, to synthesis methanol; and inputting methanol as fuel to storage base for use.

Methods and systems for the synthesis of alcohol are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and solubility of olefins in water. The high shear device may allow for lower reaction temperatures and pressures and may also reduce reaction time. In an embodiment, a method of making an alcohol comprises introducing an olefin into a water stream to form a gas-liquid stream. The method further comprises flowing the gas-liquid stream through a high shear device so as to form a dispersion with gas bubbles having a mean diameter less than about 1 micron. In addition, the method comprises contacting the gas-liquid stream with a catalyst in a reactor to hydrate the olefin gas and form an alcohol.
摘要:
A method is described for reducing sulfate ions in a first alcohol, including contacting a first alcohol comprising sulfate ions with an anion resin to reduce the concentration of sulfate ions present in the first alcohol and form a treated alcohol.
摘要:
This invention relates to a process for the production of olefins, alcohols, ethers, ethoxylates, glycols, and olefin oxides from alkanes in a halogen, preferably bromine or chlorine, system, wherein there are halogenation (reaction of halogen with the alkanes), oxidation (reaction of alkyl halide with a metal oxide), optional neutralization (reaction of hydrogen halide and metal oxide), and regeneration (reaction of metal halide with air, oxygen, or other oxygen gas containing mixtures) reactions which take place in the process and wherein at least one of the reactions wherein water and halogen and/or hydrogen halide are present is carried out in reactors made from metallurgy including zirconium and/or zirconium-based alloys that contain varying amounts of alloying elements such as tin, niobium, chromium, iron, oxygen, and nickel. Preferably, this same metallurgy is used in the fabrication of separation and purification equipment for the process.
摘要:
The invention concerns a fatty alcohol obtainable by a method which consists in reducing the carbonyl function of a vegetable or animal oil, the method consisting in: reacting said vegetable or animal oil with appropriate amounts of polymethyl-hydroxysiloxane (PMHS) in the presence of a catalytic system prepared from a metal salt or complex and a reduction agent, followed by hydrolysis of the resulting siloxane with a basic agent and separating and purifying the desired alcohol thus formed. Said alcohol can be used in a perfume composition, in particular as solubilizing agent.
