  • Publication number: 20130253239
    Abstract: A process for producing heavy alkyl aromatics is presented. The process utilizes low molecular weight hydrocarbons for generating larger alkyl groups. The hydrocarbons can be generated from a variety of sources including Fischer-Tropsch liquids. The process includes oligomerization of low molecular weight olefins to larger olefins. The larger olefins are passed to an alkylation reactor to alkylate aromatic compounds.

  • Patent number: 8536391
    Abstract: This disclosure provides for alpha olefin oligomers and polyalphaolefins (or PAOs) and methods of making the alpha olefin oligomers and PAOs. This disclosure encompasses metallocene-based alpha olefin oligomerization catalyst systems, including those that include at least one metallocene and an activator comprising a solid oxide chemically-treated with an electron withdrawing anion. The alpha olefin oligomers and PAOs prepared with these catalyst systems can have a high viscosity index combined with a low pour point, making them particularly useful in lubricant compositions and as viscosity modifiers.

  • Patent number: 8471086
    Abstract: We provide a process for producing hydrocarbon products. The process includes operating a process unit comprising a liquid catalyst in a first mode, adjusting a molar ratio of olefin to HCl, and operating the process unit in a second mode. The first mode and the second mode are different, one being a distillate mode and the other being a lubricant mode. Increasing the molar ratio of olefin to HCl provides a higher amount of a lubricant.

  • Publication number: 20130102826
    Abstract: Methods for preparing selected oligomers from monomers utilize systems of equipment adapted to provide desired compositions in various streams. Representative equipment of an oligomerization system includes an oligomer synthesis reactor and, optionally, a gas/liquid phase separation system. A monomer feed stream and a catalyst feed stream are directed to the oligomer synthesis reactor. The reactor produces a vapor phase effluent and a liquid phase effluent. The selected oligomer product is withdrawn from the vapor phase effluent. When the gas/liquid phase separation system is included, it is adapted to form a first recycle stream and a separator product stream from the vapor phase effluent. The separator product stream includes the desired oligomer product. Additional equipment may be utilized to further refine the vapor phase effluent and/or the final product stream.
