  • Publication number: 20200171475
    Abstract: Embodiments of the present disclosure describe a catalyst for dehydrocyclisation of hydrocarbons comprising a suitable support and an organometallic complex or a coordination compound including at least a dehydrogenation metal, wherein the dehydrogenation metal of the organometallic complex or coordination compound is grafted to a selected site of the suitable support. Embodiments of the present disclosure further describe a method of preparing a dehydrocyclisation catalyst for hydrocarbons comprising grafting a dehydrogenation metal of an organometallic complex or coordination compound to a selected site of a suitable support to form the dehydrocyclisation catalyst. Another embodiment of the present disclosure is a method of dehydrocyclisation of hydrocarbons comprising contacting a hydrocarbon with a dehydrocyclisation catalyst to convert the hydrocarbon to an aromatic compound, wherein the dehydrocyclisation catalyst includes a dehydrogenation metal grafted to a selected site of a suitable support.

  • Patent number: 8557022
    Abstract: A method of manufacturing a filled polymeric membrane includes a first step of preparing a filler suspension having a solvent for a glassy polymer and nanometer-sized particles. The nanometer-sized particles in the filler suspension are aggregated in aggregates having an average aggregate size in the range between 50 nm and smaller than 200 nm. In a following step, the glassy polymer is added to the filler suspension to obtain a polymer suspension. Next, the glassy polymer is dissolved in the polymer suspension. In a next step, the polymer suspension is cast on a substrate, followed by a step of removing the solvent. A filled polymeric membrane includes aggregates of nanometer-sized filler particles. The membrane is used in pervaporation and nanofiltration.

  • Publication number: 20070175829
    Abstract: Membranes consisting of an elastomeric matrix with dispersed fillers are used in the pressure driven separation of liquid feeds. The fillers are selected in such a way that the interactions between the filler and the elastomer keep the membrane swelling limited, resulting in higher rejections.
