    Abstract: Systems and methods are provided for producing upgraded raffinate and extract products from lubricant boiling range feeds and/or other feeds having a boiling range of 400° F. (204° C.) to 1500° F. (816° C.) or more. The upgraded raffinate and/or extract products can have a reduced or minimized concentration of sulfur, nitrogen, metals, or a combination thereof. The reduced or minimized concentration of sulfur, nitrogen, and/or metals can be achieved by hydrotreating a suitable feed under hydrotreatment conditions corresponding to relatively low levels of feed conversion. Optionally, the feed can also dewaxed, such as by catalytic dewaxing or by solvent dewaxing. Because excessive aromatic saturation is not desired, the pressure for hydrotreatment (and optional dewaxing) can be 500 psig (˜3.4 MPa) to 1200 psig (˜8.2 MPa).

    Abstract: A novel metal organic framework, EMM-33, is described having the structure of UiO-67 and comprising bisphosphonate linking ligands. EMM-33 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-33, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.

    IPC: G01N33/207

    Abstract: A pipeline inspection assembly includes a test pipe including at least one weld and one or more synthetic weld flaws, and a pipeline inspection device mountable to the test pipe and movable relative thereto. The pipeline inspection device includes a detection device operable to detect the one or more synthetic weld flaws as the pipeline inspection device moves along a length of the test pipe. A performance of the pipeline inspection device is assessed based on a comparison of a detected characteristic of the one or more synthetic weld flaws and a known characteristic of the one or more synthetic weld flaws.

    IPC: C10C3/08

    Abstract: Methods are provided for reducing or minimizing the temperature dependence of a pitch feed or fraction for use in carbon fiber production, such as a mesophase pitch feed or fraction or an isotropic pitch feed or fraction. A pitch sample can be characterized to determine a characteristic temperature and a characteristic viscosity for the sample. One or more solvent extraction processes can also be performed on the pitch and/or the extract and raffinate fractions formed by the solvent extraction(s). The resulting raffinate and extract fractions are then used to form a modified pitch fraction with a T0 value that is lower than the T0 value of the original pitch. The modified pitch fraction can optionally also have a different ηinf value relative to the original pitch.

    Abstract: Disclosed are Group III base stocks comprising greater than or equal to about 90 wt. % saturated hydrocarbons (saturates); a viscosity index from 120 to 145; a unique ratio of molecules with multi-ring naphthenes to single ring naphthenes (2R+N/1RN); a unique ratio of branched carbons to straight chain carbons (BC/SC); a unique ratio of branched carbons to terminal carbons (BC/TC); and unique MRV behavior as a function of base stock naphthene ratio (2R+N/1RN). A method for preparing the base stocks is also disclosed. Also disclosed is a lubricating oil having the base stock as a major component, and an additive as a minor component.
