  • Patent number: 8932972
    Abstract: This invention relates to an in-situ remanufacturing method of SCR aged catalyst. More specifically, in case the activity of the catalyst, which is used in selective catalytic reduction (SCR) to remove nitrogen oxides, is decreased, such deactivated catalyst, in this in-situ remanufacturing method, is not to be separated from its related reactor but to be remanufactured in-situ for elimination in this method, which, compared to the one that otherwise includes detachment and transportation to remanufacturing facilities, should prevent potential damage to the catalyst, reduce transportation costs as well as additional enormous costs depending upon unloading and loading of the catalyst and shorten the remanufacturing time. The activity of reclaimed catalyst in this invention is recovered at a level of 95% or more than that of fresh SCR catalyst by rapidly facilitating the in-situ elimination of any contaminant and possesses high economic efficiency as there is no catalyst loss during the process.

    Abstract: The present invention relates to new processes for regenerating oxidized interstitial metal hydride containing catalysts prior to the use of such catalysts in a hydroprocessing process. Interstitial metal hydride containing catalysts are easily oxidized in the environment and once oxidized, the hydroprocessing activity of the interstitial metal hydrides is most often severely diminished and this lost activity due to oxidization of the iMeH is not susceptible to recovery under hydroprocessing conditions. As a result, these catalysts in the present art require considerable special handling in inert environments all through processes from fabrication, shipping, loading, use, and maintenance of the catalyst systems to protect the activity of the interstitial metal hydride components.

    Abstract: An apparatus suitable for generating gaseous hydrocarbon fuel from a carbon based synthesis gas including a reaction chamber having a rotating shaft including a plurality of radial blades mixing and circulating carbon based synthesis gas and particulate catalyst upwardly generating gaseous hydrocarbon fuel, a stripping chamber located above the reaction chamber having a second axial rotating shaft including a plurality of radial blades driving hydrocarbon fuel radially outwardly, a source of hot stripping gas, an annular filter surrounding the stripping chamber and an annular gas collection chamber surrounding the filter. The blades in the stripping chamber are rotated independently at a greater velocity than the blades in the reaction chamber and the reaction is controlled by the temperature of the synthesis gas and the rotational velocity of the mixing blades in the reaction chamber.

  • Patent number: 8227367
    Abstract: The invention relates to a conversion process for making olefin(s) using a molecular sieve catalyst composition. More specifically, the invention is directed to a process for converting a feedstock comprising an oxygenate in the presence of a molecular sieve catalyst composition, wherein the air feed to the catalyst regenerator is free of or substantially free of metal salts. The air feed is first cooled to remove water and then washed with water to remove essentially all salts from said air feed. The water removed in the cooling step is preferably recirculated to wash the salts from the air feed.

  • Patent number: 8178461
    Abstract: A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via membrane filtration. Residual hydrocarbons, i.e., heavy oil and solvent employed in the filtration for the heavy oil extraction are removed from the catalyst particles in a drying zone which employs at least two drying apparatuses to volatize residual hydrocarbons in the catalyst. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst.

  • Patent number: 8110523
    Abstract: Disclosed herein is a method for preparing a dry regenerable sorbent which comprises the steps of obtaining a slurry through formulation, mixing, comminuting and dispersion of the sorbent raw materials, forming the slurry by spray drying to produce sorbent particles, and calcining the sorbent particles. In the step of obtaining a slurry, there is used organic additives (dispersant, a flow control agent, and an organic binder) necessary to obtain a well-dispersed, stable and free-flowing slurry in which the raw materials are present below a sub-micron level (nanosize). The organic additives are removed and decomposed through the calcining. The use of the hydrophilic and high specific surface area support allows the dry regenerable sorbent to have a high reactivity. The solid active component is used instead of a liquid amine used in a conventional wet carbon dioxide capture technology. In addition, the sorbent can be re-used through continuous sorption and regeneration processes.

  • Patent number: 7985704
    Abstract: A method of regenerating an absorbent includes preparing a reactor having a gas inlet portion and a discharge portion, filling the reactor with a reforming catalyst and an absorbent for absorbing carbon dioxide, feeding the feedstock gas and the steam via the gas inlet portion to the reactor to allow a steam reforming reaction to take place, allowing the absorbent to absorb carbon dioxide generated with hydrogen at the steam reforming reaction, and releasing the carbon dioxide from the absorbent after the carbon dioxide absorption capacity of the absorbent has been degraded. In this method, the temperature in an inside of the reactor is set to 625° C. or more at the release of the carbon dioxide, and an inert gas is fed via the discharge portion to the reactor.
