Abstract: Systems and methods are provided for producing lubricant basestocks having a reduced or minimized aromatics content. A first processing stage can perform an initial amount of hydrotreating and/or hydrocracking. A first separation stage can then be used to remove fuels boiling range (and lower boiling range) compounds. The remaining lubricant boiling range fraction can then be exposed under hydrocracking conditions to a USY catalyst including a supported noble metal, such as Pt and/or Pd. The USY catalyst can have a desirable combination of catalyst properties, such as a unit cell size of 24.30 or less (or 24.24 or less), a silica to alumina ratio of at least 50 (or at least 80), and an alpha value of 20 or less (or 10 or less). In some aspects, the effluent from the second (hydrocracking) stage can be dewaxed without further separation. In such aspects, a portion of the dewaxed effluent can be used as a recycle quench stream to cool the hydrocracking effluent prior to entering the dewaxing reactor.

Abstract: A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more large pore zeolitic catalysts, which may be prepared from a precursor zeolite. In some examples, a large pore zeolitic catalyst may be utilized to selectively reduce the endpoint of a hydrocarbon composition.

Abstract: Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced in powder form. Extrusion of powder-form MOFs to produce shaped bodies has heretofore proven difficult due to loss of surface area and poor crush strength of MOF extrudates, in addition to phase transformations occurring during extrusion. The choice of mixing conditions and the mixing solvent when forming MOF extrudates can impact these factors. Extrudates comprising a MOF consolidated material may feature the MOF consolidated material having a BET surface area of about 50% or greater relative to that of a pre-crystallized MOF powder material used to form the extrudate. X-ray powder diffraction of the extrudate shows about 20% or less conversion of the MOF consolidated material into a phase differing from that of the pre-crystallized MOF powder material.

Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.
