The present invention provides an organometal catalyst having a cationic metal complex and a borate-based bulky anion, where the metal is one or more selected from the group consisting of metals in group 13, a method for preparing the same, and a method for preparing an oligomer or a polymer using the same.

A method for making organo-metal material involves providing a metal ion source in a medium that removes metal ions from the source and forms 1D metal-containing coordination polymers that self-assemble and precipitate as at least one of a 2D and 3D coordination polymer material that can be thermally treated to produce a porous metal oxide material.

A nanocage-confined catalyst has the formula: NC-m[M(Salen1)X]-n[M′(Salen2)]. NC is a material having a nanocage structure, and M(Salen1)X and M′ (Salen2) are active centers, respectively; each occurrence of M is independently selected from the group consisting of Co ion, Fe ion, Ga ion, Al ion, Cr ion, and a mixture thereof. Each occurrence of M′ is independently selected from Cu ion, Ni ion and a mixture thereof, m is 0 to 100; n is 0 to 100, with the proviso that at least one of m and n is not 0; each occurrence of Salen1 and Salen2 is independently a derivative of Shiff bases; X is an axial anion selected from the group consisting of substituted or unsubstituted acetate, substituted or unsubstituted benzene sulfonate, substituted or unsubstituted benzoate, F—, Cl—, Br—, I—, SbF6-, PF6-, BF4-, and a mixture thereof.

The present invention provides an organometal catalyst having a cationic metal complex and a borate-based bulky anion, where the metal is one or more selected from the group consisting of metals in group 13, a method for preparing the same, and a method for preparing an oligomer or a polymer using the same.

A process is provided for the selective oligomerisation of C5 to C20 alpha-olefins to produce polyalphaolefin oligomers with a molecular weight distribution that is suitable for use in lubricant base oils.

Processes for regenerating ionic liquid catalyst in which reaction vessel is operated under conditions sufficient to perform, in the presence of an ionic liquid catalyst, a hydrocarbon conversion reaction and provide a reaction effluent. The reaction effluent is separated into a hydrocarbon phase and a spent ionic liquid catalyst, wherein the spent ionic liquid catalyst includes conjunct polymer. The spent ionic liquid catalyst is contacted with hydrogen in a regeneration zone at conditions sufficient to reduce an amount of conjunct polymer in the spent ionic liquid catalyst to provide a regenerated effluent. The regenerated effluent is separated into a liquid phase comprising regenerated ionic liquid catalyst and a vapor phase comprising hydrogen and hydrogen chloride. The hydrocarbon phase is separated into a plurality of liquid hydrocarbon streams. The vapor phase is isolated from the liquid hydrocarbon streams. Alkylation processes are also disclosed.

A process to form a cyclic olefin polymerization catalyst which includes contacting a metal alkoxide with a transition metal halide to form a transition metal precatalyst, and contacting the transition metal precatalyst with a metal alkyl activator to form the activated catalyst comprising a transition metal carbene moiety. A cyclic olefin polymerization process is also disclosed.
