  • Patent number: 10662061
    Abstract: Embodiments of the disclosure provide a method and a Claus tail gas treatment system for sulfur recovery. A tail gas stream is fed to a hydrogenation reactor to produce a hydrogenated gas stream by converting sulfur-containing compounds to hydrogen sulfide. The hydrogenated gas stream is fed to a quench tower to produce a quenched gas stream by condensing and recovering liquid water via a water condensate stream. The quenched gas stream is fed to a first stage adsorption unit to produce a first outlet gas stream by separating water via a first byproduct stream from hydrogen sulfide, carbon dioxide, and nitrogen. The first outlet stream is fed to a second stage adsorption unit to produce a second outlet gas stream by separating carbon dioxide and nitrogen via a second byproduct stream. The second outlet stream includes hydrogen sulfide. The second outlet stream can be fed to a Claus unit.

    Abstract: Embodiments provide a methane microporous carbon adsorbent including a thermally-treated CVD carbon having a shape in the form of a negative replica of a crystalline zeolite has a BET specific surface area, a micropore volume, a micropore to mesopore volume ratio, a stored methane value and a methane delivered value and a sequential carbon synthesis method for forming the methane microporous carbon adsorbent. Introducing an organic precursor gas for a chemical vapor deposition (CVD) period to a crystalline zeolite that is maintained at a CVD temperature forms the carbon-zeolite composite. Introducing a non-reactive gas for a thermal treatment period to the carbon-zeolite composite maintained at a thermal treatment temperature forms the thermally-treated carbon-zeolite composite. Introducing an aqueous strong mineral acid mixture to the thermally-treated carbon-zeolite composite forms the methane microporous carbon adsorbent.

  • Patent number: 9818740
    Abstract: An integrated circuit includes an NMOS transistor, a PMOS transistor and a vertical bipolar transistor. The vertical bipolar transistor has an intrinsic base with a band barrier at least 25 meV high at a surface boundary of the intrinsic base, except at an emitter-base junction with an emitter, and except at a base-collector junction with a collector. The intrinsic base may be laterally surrounded by an extrinsic base with a higher dopant density than the intrinsic base, wherein a higher dopant density provides the band barrier at lateral surfaces of the intrinsic base. A gate may be disposed on a gate dielectric layer over a top surface boundary of the intrinsic base adjacent to the emitter. The gate is configured to accumulate the intrinsic base immediately under the gate dielectric layer, providing the band barrier at the top surface boundary of the intrinsic base.
