摘要： In at least one embodiment, a process to produce a poly alpha-olefin (PAO) includes introducing a first alpha-olefin to a first catalyst system comprising activator and a metallocene compound into a continuous stirred tank reactor or a continuous tubular reactor under first reactor conditions to form a first reactor effluent. The first alpha-olefin is introduced to the reactor at a flow rate of about 100 g/hr or more. The first reactor effluent includes at least 60 wt % of PAO dimer and 40 wt % or less of higher oligomers, where the higher oligomers are oligomers that have a degree of polymerization of 3 or more. The process includes introducing the first reactor effluent and a second alpha-olefin to a second catalyst composition including an acid catalyst in a second reactor to form a second reactor effluent comprising PAO trimer.

摘要： A process for making a poly alpha-olefin (PAO) having a relatively high vinylidene content (or combined vinylidene and tri-substituted vinylene content) and a relatively low vinyl and/or di-substituted vinylene content, as well as a relatively low molecular weight. The process includes: contacting a feed containing a C2-C32 alpha-olefin with a catalyst system comprising activator and a bis-cyclopentadienyl metallocene compound, typically a cyclopentadienyl-benzindenyl group 4 transition metal compound.

摘要： The present disclosure provides processes and apparatus for producing poly alpha olefins. In at least one embodiment, a process to produce a poly alpha olefin includes introducing a first olefin monomer to a first catalyst and an activator in a first reactor to form a first reactor effluent comprising an olefin dimer and an olefin trimer. The process includes introducing the first reactor effluent to a filtration unit to form a filtration effluent, and introducing the filtration effluent to a first distillation unit to form a first distillation effluent. The process includes introducing the first distillation effluent (or a second distillation effluent) to a second catalyst in a second reactor to form a second reactor effluent comprising the olefin trimer. The process includes removing a sample at any stage of the process and introducing the sample to a gas chromatograph.

摘要： A composition and methods for making the same. The composition includes an isoolefin having from 4 to 7 carbons, a first styrene, and a second styrene alkylated with a diene to have a pendant double bond. A copolymer having units derived from an isoolefin having from 4 to 7 carbons and an alkylstyrene can be reacted with a diene to provide the composition. The reaction of the copolymer with the diene can be reacted in the presence of a catalyst at a temperature of about 80° C. to about 200° C.

摘要： Vinylidene olefins may undergo hydroformylation in the presence of an unmodified cobalt catalyst to form compositions comprising a mixture of alcohol molecules having a specified amount of branching. In particular, the compositions may feature a mixture comprising reduced hydroformylated reaction products of a vinylidene olefin comprising alcohol molecules represented by at least one of Structures 3-5. The mixture has an average of about 1.2 to about 2.1 branches per alcohol molecule. Ra and Rb may be the same or different and comprise a branched or unbranched alkyl group having about 6 to about 14 carbon atoms, excluding branches. Variable m is an integer ranging from 0 to a number of carbon atoms in Rb. Rb is a branched or unbranched alkyl group having m+1 carbon atoms less than Rb.
