More specifically, the present invention relates to a method of carrying out methane steam reforming using a nickel/alumina nanocomposite catalyst wherein nickel metal nanoparticles are uniformly loaded in a high amount on a support via a melt infiltration method with an excellent methane conversion even under a relatively severe reaction condition of a high gas hourly space velocity or low steam supply, and to a catalyst for this method. In addition, the present invention prepares a nickel/silica-alumina hybrid nanocatalyst by mixing the catalyst prepared by the melt infiltration method as the first catalyst and the nickel silica yolk-shell catalyst as the second catalyst, and applies it to the steam reforming of methane to provide a still more excellent catalytic activity even under the higher temperature of 700° C. or more with the excellent methane conversion.

  • Patent number: 10184088
    Abstract: A fluid catalytic cracking apparatus and process is disclosed, providing for efficient conversion of heavy hydrocarbon feeds to light olefins, aromatics, and gasoline. A countercurrent flow reactor operating in bubbling or turbulent fluidization regimes is integrated with a fluid catalytic cracking riser reactor. A heavy hydrocarbon feed is catalytically cracked to naphtha and light olefins in the riser reactor, a co-current flow reactor. To enhance the yields and selectivity to light olefins, cracked hydrocarbon products from the riser reactor, such as C4 and naphtha range hydrocarbons, may be recycled and processed in the countercurrent flow reactor. The integration of the countercurrent flow reactor with a conventional FCC riser reactor and catalyst regeneration system may overcome heat balance issues commonly associated with two-stage cracking processes, may substantially increase the overall conversion and light olefins yield, and/or may increases the capability to process heavier feedstocks.

  • Patent number: 10143966
    Abstract: Active catalysts for the treatment of a low temperature exhaust gas stream are provided containing potassium (K) dispersed on a spinel oxide for the direct, lean removal of nitrogen oxides from the exhaust gas stream. The low temperature (from about 400° C. to about 650° C.), direct decomposition is accomplished without the need of a reductant molecule. In one example, K may be dispersed on a surface of a metal oxide support, such as NiFe2O4 spinel oxide, synthesized using wet impregnation techniques. The K/NiFe2O4 catalyst system converts nitric oxide to nitrogen gas with high product specificity, up to 100%, avoiding the production of a significant concentration of the undesirable N2O product.

  • Patent number: 9850434
    Abstract: A method of predicting the tendency of a heavy oil feed to generate coke deposits in the FCC riser under a given set of operating parameters in the unit; thus, by utilizing operating parameters appropriate to the feed, the formation of coke deposits in the riser may be minimized. The margin between the theoretical dew point of the hydrocarbon feed established from unit operating parameters and the theoretical mix zone temperature in the feed injection zone of the unit is developed by applying a regression-derived linear model from multiple rigorous model runs. The mix zone of the unit is then operated at a temperature which reduces the level of riser coking predicted from this ascertainable margin or, at least, maintains it within levels which are predictable and acceptable.

    Abstract: A process for increasing the yield of C3 olefin in fluidized bed catalytic cracking of hydrocarbon feedstocks is disclosed. C4 fraction produced from the cracking of hydrocarbon feedstock in the primary reaction zone (riser), optionally with external source of C4 stream is fed into the stripper which acts as a secondary reaction zone at an elevated temperature and at an optimum WHSV. The elevated temperature is achieved by injecting a part of the regenerated catalyst from regenerator, which is at a higher temperature, directly into the stripper through a dedicated additional lift line. This raises the activity of catalyst inside the stripper. The direct injection of regenerated catalyst into the stripper, besides producing higher yields of propylene, improves the stripping efficiency leading to enhanced recovery of strippable hydrocarbons.

The method includes contacting a first hydrocarbon stream with a first cracking catalyst at a first cracking temperature in a first riser to produce a first riser effluent and a first spent catalyst. A second hydrocarbon stream is contacted with a second cracking catalyst at a second cracking temperature in a second riser to produce a second riser effluent and a second spent catalyst, where the second cracking temperature is less than the first cracking temperature. The first riser effluent and the second riser effluent are combined to produce a mixed riser effluent, and the mixed riser effluent is fractionated in a fractionation zone to produce a light cycle oil. The first spent catalyst and the second spent catalyst are combined in a reactor to produce a mixed spent catalyst.

  • Patent number: 9469815
    Abstract: A process for catalytic cracking of a pyrolysis oil derived from material comprising biomass. In one embodiment, the process comprises subjecting a feed comprising the pyrolysis oil to a hydrodeoxygenation step to prepare an at least partially deoxygenated pyrolysis oil; heating a hydrocarbon feed to a temperature in the range from equal to or more than 50° C. to equal to or less than 200° C. to prepare a preheated hydrocarbon feed; mixing the at least partially deoxygenated pyrolysis oil and the preheated hydrocarbon feed to prepare a feed mixture; and contacting the feed mixture with a catalytic cracking catalyst in a catalytic cracking reactor at a temperature of at least 400° C. to prepare a product stream containing one or more cracked products.

  • Patent number: 9446368
    Abstract: A mixing device used in a fluidized catalytic cracking apparatus which mixes feed and a catalyst includes a cylindrical reaction container which supplies a catalyst in a vertical direction; a plurality of feed injection nozzles arranged along an outer circumference of the reaction container; and a catalyst flow regulator which is provided in the reaction container and regulates a flow of the catalyst in the vicinity of the feed injection nozzles. The catalyst flow regulator has no feed supply function and forms a catalyst moving bed having a hollow tubular shape which is coaxial with the reaction container in the vicinity of the feed injection nozzles. The catalyst flow regulator can effectively prevent backward flow of injected fuel. Although the mixing device has a simple structure, it has a high cracking rate and maintenance of the fluidized catalytic cracking apparatus can be performed easier.

  • Patent number: 9376638
    Abstract: A process for the hydroconversion of a hydrocarbon feedstock. The process includes contacting the hydrocarbon feedstock with a catalyst in a first hydrocracking section to obtain a first hydrocarbon effluent stream which is separated into a gaseous stream, a light liquid stream and a heavy liquid stream. These liquid streams are fractioned into a number of fractions of hydrocarbons including a fraction of hydrocarbons having a boiling point above 350° C. This fraction of hydrocarbons is contacted with a catalyst in a second hydrocracking section to obtain a second hydrocarbon effluent stream that is separated to obtain a gaseous stream, a light liquid stream and a heavy liquid stream. These liquid streams are fractioned into a number of fractions of hydrocarbons including a heavy fraction of hydrocarbons having a boiling point above 350° C. This fraction of hydrocarbons is split into a major stream and a minor stream with the major stream being recycled and the minor stream is recovered.
