  • Patent number: 10421058
    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: 9605213
    Abstract: Embodiments of the invention provide a method for the fluid catalytic cracking of a heavy hydrocarbon feedstock. According to at least one embodiment, the method includes supplying the heavy hydrocarbon feedstock to a reaction zone having a catalyst, such that both the heavy hydrocarbon feedstock and the catalyst are in contact in a down-flow mode, wherein said contact between the heavy hydrocarbon feedstock and the catalyst takes place in a fluidized catalytic cracking apparatus having a separation zone, a stripping zone, and a regeneration zone. The method further includes maintaining the reaction zone at a temperature of between 500 and 600° C., such that the hydrocarbon feedstock converts into a cracked hydrocarbon effluent comprising light olefins, gasoline, and diesel.

  • Patent number: 9403148
    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.
