  • Publication number: 20220298087
    Abstract: 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.
