摘要： The invention provides fermentative methods for producing n-propanol. The methods of the invention involve providing a suitable carbon source, a microorganism expressing the dicarboxylic acid pathway, reducing equivalents, and at least one gene coding for an enzyme that catalyzes the conversion of propionate/propionyl-CoA into n-propanol. The methods further involve contacting the carbon source and reducing equivalents with the microorganism under conditions favorable for the production of n-propanol. Also provided are methods for producing propylene and polypropylene from the n-propanol and microorganisms suitable for use in the methods of the invention

摘要： The present invention relates to a method for the production of an olefin from at least one renewable natural raw material. More specifically, the present invention refers to a method whereby is obtained ethylene or propylene at high yield and high productivity by means of the anodic electrodecarboxylation reaction of carboxylic acids, respectively propionic acid and butyric acid, produced from fermentation, preferably of sugars. The method for generating the olefin is simple, has a low cost, and provides low emissions of greenhouse gasses of fossil origin.

摘要： The present invention relates to a process for the production of propene from a mixture of alcohols obtained from at least one renewable source of carbon, comprising the following steps: (a) fermentation of at least one renewable source of carbon for the production of a mixture of alcohols comprising ethanol, isopropanol and 1-butanol; (b) simplified removal of the alcohols from the fermentative wort to generate an aqueous solution containing chiefly ethanol, isopropanol and 1-butanol; (c) joint dehydration of the alcohols to produce a mixture of olefins comprising chiefly ethene, propene and linear butenes, the linear butenes being a mixture of 1-butene and 2-butenes (cis and trans isomers), besides water and by-products, among which oxygenated compounds; (d) removal of water, oxygenated compounds and other by-products to generate a mixture of olefins comprising chiefly ethene, propene and linear butenes; and (f) passing the mixture of olefins through an isomerized bed, so that 1-butene will be isomerized to 2-butenes and, subsequently, passing the mixture of olefins comprising chiefly ethene, propene and 2-butenes through a metathesis bed, for reaction between ethene and 2-butenes, generating additional propene, the molar ratio ethene:linear butenes being corrected to be between 1:1 and 1.3:1, by means of one of the alternatives selected from the group comprising: (i) addition of a stream containing ethanol to the process in step (c); (ii) addition of a stream containing ethene to the process in step (e); (iii) addition of a stream containing ethanol to the process in step (c) and a stream containing ethene in step (e).
