    摘要: A method and reactor for catalytic hydroprocessing liquid hydrocarbon feedstock at elevated temperatures and pressures for producing a liquid hydrocarbon product involves introducing the feedstock into a reactor having upper and lower reaction zones, each reaction zone having a hydroprocessing catalyst bed therein, the feedstock being introduced at the top of the lower reaction zone for downward flow through and reaction within the catalyst bed therein; collecting a partially reacted liquid effluent from the lower reaction zone; pumping the partially reacted liquid effluent to and introducing it at the top of the upper reaction zone for downward flow through and reaction within the catalyst bed therein; introducing hydrogen gas at the top of the upper reaction zone for flow downwardly and sequentially through and over the catalyst beds in the upper and lower reaction zones in co-current contact with the liquid in the reaction zones, the hydrogen reacting with the liquid in the reaction zones whereby the liquid effluent from the upper reaction zone comprises a liquid hydrocarbon product; and collecting and recovering the liquid hydrocarbon effluent product from the upper reaction zone.

    摘要: Removing sulfur oxide and carbon monoxide in a flue gas stream by combusting fuel in the combustor with a reduced amount of oxygen to partially convert carbon monoxide therein to carbon dioxide and sufficient to convert all sulfur-containing species in the flue gas stream to sulfur oxide and thus form a sulfur oxide enriched gas stream having between at least about 500 ppm carbon monoxide. The sulfur oxide enriched gas stream is contacted with a solid adsorbent bed for adsorbing the sulfur oxides in the form of inorganic sulfates and/or sulfur oxides. The solid adsorbent contains a catalytic oxidation promoter for oxidizing the carbon monoxide gas stream to carbon dioxide, thus forming a sulfur oxide and carbon monoxide depleted stream for disposal. The adsorbent bed is then contacted with a reducing gas stream for regenerating the adsorbent bed to form a hydrogen sulfide and/or sulfur dioxide bearing stream.

    摘要: A cyclone and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added tangentially around a vapor outlet tube in a cylindrical tube cyclone body. Solids and some gas is withdrawn via a plurality of openings radially and longitudinally distributed in the cylindrical sidewall of the cyclone body. Distributed withdrawal replaces or reduces conventional underflow of solids from an end of cyclone outlet and reduces solids reentrainment. 0-5 micron particle removal is enhanced by reducing eddy formation and particle bouncing near the cyclone sidewall. The device may be used as an FCC regenerator third stage separator.

    摘要: The present invention relates to an in-line method for generating comonomer, such as 1-hexene or 1-octene, from monomer, such as ethylene. The comonomer generated is directly transported, without isolation or storage, to a polyethylene polymerization reactor. The in-line method for generating comonomer includes the steps of providing an in-line comonomer synthesis reactor and a downstream gas/liquid phase separator prior to a polyethylene polymerization reactor; feeding ethylene monomer and a catalyst in a solvent to the comonomer synthesis reactor; reacting the ethylene monomer and the catalyst in solvent under reaction conditions to produce an effluent stream including ethylene monomer and comonomer; passing the effluent stream from the comonomer synthesis reactor to the downstream gas/liquid phase separator to separate a gas stream from a bottom stream, wherein the gas stream is a mixture of ethylene monomer, and comonomer; and passing the gas stream to the polyethylene polymerization reactor to provide the necessary comonomer input. The in-line method is useful in the production of LLDPE, and other branched polyethylene based polymers. Some benefits include process simplification and reduced capital and operating costs.

    摘要: A multi-bed process of removing sulfur oxides and/or other combustible sulfur-containing compounds from a gas stream including combusting the other combustible sulfur-compounds when present in the gas stream with air or oxygen to convert such sulfur-containing compounds to sulfur oxide and form a sulfur oxide enriched gas stream. The sulfur oxide enriched gas stream is contacted with first and second serially connected solid adsorbent beds for adsorbing the sulfur oxides in the form of inorganic sulfates and/or sulfur oxides. A third adsorbent bed is contacted with a reducing gas stream to regenerate the bed by reducing the retained inorganic sulfates and/or sulfur oxides to hydrogen sulfide and/or sulfur dioxide, to thereby form a hydrogen sulfide and/or sulfur dioxide bearing stream. The feeds to each of the beds are realigned to place the second and third beds in series with the sulfur oxide and/or sulfur dioxide enriched stream being fed to the second bed and to place the first bed in a regenerative mode. Thereafter, the foregoing steps are repeated whereby each of the three beds are sequentially placed in an initial bed mode in the series, a regenerative mode, and a second bed mode in the series.
