摘要:
An object of the present invention is to provide a process for producing an octadiene from 2,7-octadienyl formate in an industrially useful manner in which palladium can maintain its catalytic activity for a long period of time. More specifically, the present invention relates to a process for producing an octadiene which includes the steps of continuously adding 2,7-octadienyl formate into a reaction system in which a mixture of a palladium compound, a tertiary organophosphorus compound and a solvent is present; and subjecting the 2,7-octadienyl formate to reaction while continuously distilling off a reaction product containing the resulting octadiene out of the reaction system.

Methods and compositions for the production of oil, fuels, oleochemicals, and other compounds in Prototheca are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Prototheca cells containing exogenous genes encoding, for example, a lipase, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a fatty acyl-ACP thioesterase, a fatty acyl-CoA/aldehyde reductase, a fatty acyl-CoA reductase, a fatty aldehyde reductase, a fatty aldehyde decarbonylase, and/or an acyl carrier protein are useful in manufacturing transportation fuels such as renewable diesel, biodiesel, and renewable jet fuel.

摘要:
A process for making a bio-naphtha and optionally bio-propane from a complex mixture of natural occurring fats & oils, wherein - said complex mixture is subjected to a refining treatment for removing the major part of non-triglyceride and non-fatty acid components, thereby obtaining refined fats & oils; - said refined fats & oils are transformed into linear or substantially linear paraffin's as the bio-naphtha by an hydrodeoxygenation - or from said refined fats & oils are obtained fatty acids that are transformed into linear or substantially linear paraffin's as the bio-naphtha by hydrodeoxygenation or decarboxylation of the free fatty acids - or from said refined fats & oils are obtained fatty acids soaps that are transformed into linear or substantially linear paraffin's as the bio-naphtha by decarboxylation of the soaps.
