  • Publication number: 20220054986
    Abstract: Porous filters having uniform pore size and close packing density are described, along with methods and apparatus for making the porous filters based on nanopatterning. One method includes applying a polymeric liquid to a mold consisting of an array of posts having a desired pore size and distribution. Solidification of polymeric membrane followed by separation from the mold produces a polymer membrane with a predetermined spaced array of pores. A pre-filter film can also be bonded with the membrane during formation to provide increased mechanical support and filtration of larger particles on the input side of the filter. Other process variants are described, including methods for incorporating additional functionalities to the filter.

  • Publication number: 20160145508
    Abstract: Methods are provided for hydrotreating a feed to generate a product with a reduced or minimized aromatics content and/or an increased distillate product yield. A distillate boiling range feed having an elevated content of sulfur and/or nitrogen can be hydrotreated using at least two hydrotreating stages with intermediate separation to produce a hydrotreated distillate boiling range product with a reduced or minimized aromatics content. Additionally or alternately, a mixed metal catalyst formed from a suitable precursor can be used during the hydrotreating. A mixed metal catalyst formed from a suitable precursor can provide an unexpectedly superior activity for aromatic saturation. A still further unexpected benefic can be achieved by combining a multi-stage hydrotreating process with intermediate separation with hydrotreating in the presence of a mixed metal catalyst formed from a suitable precursor.

  • Publication number: 20160115402
    Abstract: Systems and methods are provided for producing an improved product slate during hydrocracking of a feedstock that results in production of naphtha and distillate fuels. The methods can include use of stacked beds and/or sequential reactors so that a feedstock is exposed to suitable catalysts under hydrocracking conditions and aromatic saturation conditions. The catalyst for performing the aromatic saturation process can be a catalyst including a Group VIII noble metal, such as Pt, Pd, or a combination thereof, while the hydrocracking catalyst can include Group VIB and Group VIII non-noble metals.
