Abstract: A method of using the natural gas storage facility to reduce the effect of diurnal demand on a natural gas source includes introducing natural gas into the natural gas storage facility, separating the natural gas into a heavy natural gas component and a light natural gas component, and retaining the components during a non-peak period of demand. The natural gas storage facility includes a guard bed system and an adsorption bed system. The method also includes releasing the heavy and light natural gas components, mixing them into a released natural gas component product and introducing it to the natural gas source during a peak period of demand.

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.

Abstract: A method of forming the highly selective ultra-small pore amorphous adsorbent includes introducing an ion-exchange material to a sodium aluminosilicate zeolite such that an ion-exchanged zeolite forms, calcinating the ion-exchanged zeolite at a calcination temperature such that the ion-exchanged zeolite collapses and forms the decationized amorphous adsorbent, and introducing a back ion-exchange material to the decationized amorphous adsorbent such that the highly selective ultra-small pore amorphous adsorbent forms. The highly selective ultra-small pore amorphous adsorbent has a pore aperture size operable to permit carbon dioxide to adsorb into the amorphous adsorbent and operable to deny methane from adsorbing into the amorphous adsorbent.

Abstract: The present invention relates to an amorphous adsorbent composition capable of purifying a gaseous hydrocarbon fraction and methods for synthesizing the composition. The composition is advantageously capable of filtering non-combustible contaminants for increasing the quality and heating value of a gaseous hydrocarbon such as methane.

Abstract: A methane microporous carbon adsorbent comprising 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.
