摘要:
The invention relates to a method of treating a hydrocarbon containing formation, comprising: (a) providing a composition to at least a portion of the hydrocarbon containing formation, wherein the composition comprises water and an anionic surfactant which is an internal olefin sulfonate (IOS), which has a weight ratio of branched IOS molecules to linear IOS molecules N which is greater than 0 to smaller than 11:89; and (b) allowing the composition to interact with the hydrocarbons in the hydrocarbon containing formation. Further, the invention relates to a hydrocarbon recovery composition which comprises the composition used in said method, and to a hydrocarbon containing composition produced from a hydrocarbon containing formation which in addition to hydrocarbons contains the composition used in said method.
摘要:
A solution to the problem of reducing the bulk and weight of detergents for delivery to users by providing in at least one embodiment an in situ, discrete, batch mixing method and system for a diluent and concentrated detergent at a point of dispense. While some systems are designed to mix diluents and detergents, those systems are typically designed for continuous flow, for example, in a manufacturing facility. The present invention provides for mixing the diluent and detergents in discrete batches sized for a user at the point of dispense, using a method and system that can be located even in remote areas without an external power supply. The system and method only needs diluent line pressure in at least one embodiment. Further, the method and system controls access to the batch quantity so that multiple batches are not unintentionally extracted. The method and system can be used with vending machines placed on site.
摘要:
A process for the double bond isomerization of a vinylidene olefin, comprising contacting a feed comprising the vinylidene olefin with an isomerization catalyst which comprises a molecular sieve in an acidic form, which molecular sieve comprises pores which have a pore size of more than 0.6 nm; and a process for treating an olefin mixture which comprises a linear α-olefin and a vinylidene olefin which is isomeric to the linear α-olefin and which is of the general formula CH2═C(R1)R2, wherein R1 represents an ethyl group and R2 represents a linear 1-alkyl group, which process comprises isomerizing the vinylidene olefin to form a double bond isomer of the vinylidene olefin by contacting a feed comprising the olefin mixture with an isomerization catalyst which comprises a molecular sieve in an acidic form, which molecular sieve comprises pores which have a pore size of more than 0.6 nm, and separating the linear α-olefin from the double bond isomer of the vinylidene olefin.

A process for the double bond isomerization of an olefin, which process comprises contacting a feed comprising the olefin with an isomerization catalyst, wherein prior to contacting the feed with the isomerization catalyst one or more components of the feed are pretreated by contacting with a pretreating material which comprises a zeolite which has a pore size of at least 0.35 nm; a plant which is suitable for carrying out the isomerization process; and a process for treating an olefin mixture which comprises a linear α-olefin and a vinylidene olefin which is isomeric to the linear α-olefin and which is of the general formula CH2═C(R1)R2, wherein R1 represents an ethyl group and R2 represents a linear 1-alkyl group, which process comprises isomerizing the vinylidene olefin to form a double bond isomer of the vinylidene olefin by contacting a feed comprising the olefin mixture with an isomerization catalyst, and separating the linear α-olefin from the double bond isomer of the vinylidene olefin, wherein prior to contacting the feed with the isomerization catalyst one or more components of the feed are pretreated by contacting with a pretreating material which comprises a zeolite which has a pore size of at least 0.35 nm.
