  • Patent number: 8877042
    Abstract: The production of light hydrocarbons consisting of ethylene, propylene, butylenes, and of gasoline is enhanced by introducing a heavy oil feedstream derived from an external source into an ancillary downflow reactor that utilizes the same catalyst composition as an adjacent FCC unit for cracking the heavy oil and withdrawing the desired lighter hydrocarbon reaction product stream from the downflow reactor and regenerating the catalyst in the same regeneration vessel that is used to regenerate the spent catalyst from the FCC unit. The efficiency of the recovery of the desired lighter olefinic hydrocarbons is maximized by limiting the feedstream to the downflow reactor to heavy oils that can be processed under relatively harsher conditions, while minimizing production of undesired by-products.

  • Patent number: 8852822
    Abstract: When terminating power generation by a fuel cell 3 in a fuel cell system 1, an amount of a raw fuel material introduced to a reforming catalyst 2a of a reformer 2 is reduced. Here, before the temperature of the reforming catalyst 2a is lowered to the un-reformed gas generation temperature, an amount of water supplied to the reforming catalyst 2a is controlled to increase the temperature of the reforming catalyst 2a. Thus, upon termination of power generation in the fuel cell 3, no un-reformed gas is generated and the reformed gas is supplied to the fuel cell 3.
