    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 catalyst precursor composition comprising: a) a source of chromium, molybdenum or tungsten; b) a first ligand having the general formula (I); (R1)(R2)P—X—P(R3)(R4)  (I) wherein: X is a bridging group of the formula —N(R5)—, wherein R5 is selected from hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, a substituted heterohydrocarbyl group, a silyl group or derivative thereof; at least three of R1 to R4 are independently selected from optionally substituted aromatic groups, each bearing a polar substituent on at least one of the ortho-positions; and optionally one of R1 to R4 is independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; c) a second ligand having the general formula (II); (R1′)(R2′)P—X′—P(R3′)(R4′)  (II) wherein: X′ is a bridging group as defined for X of the first ligand, component (b), of general formula (I); at least R1′ and R2′ of R1′ to R4′ are independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; and optionally none, one or both of R3′ and R4′ are independently selected from an optionally substituted aromatic group bearing a polar substituent on at least one of the ortho-positions. The present invention also relates to a catalyst system comprising the catalyst precursor composition of the present invention and additional component; d) a cocatalyst. The present invention further relates to a process for the trimerization and tetramerization of olefinic monomers, particularly the trimerization and tetramerization of ethylene to 1-hexene and 1-octene, wherein the process comprises contacting at least one olefinic monomer with the catalyst system of the present invention.
