  • Publication number: 20040134836
    Abstract: In a vertical reactor vessel through which vapor and liquid flow concurrently, the fluids pass vertically through a horizontal mixing box having internal flow baffles that form at least one mixing orifice through which the process stream flows at high velocity. In the mixing orifices the liquid is dispersed to obtain a large area for interphase heat and mass transfer. Each mixing orifice is followed by structure that divides the process stream into two lower velocity streams, whereby turbulent flow conditions are generated, and wherein hold-up time is provided to allow for heat and mass transfer. The fluids exit the mixing box through an outlet opening in a bottom wall of the mixing box. An impingement plate is located below this outlet opening to spread the liquid and decrease the velocity of the exiting jet. The outlet stream from the mixer is equilibrated regarding temperature and chemical composition.

  • Patent number: 6755963
    Abstract: This invention provides a process for hydrotreating hydrocarbon resins, which process comprises contacting a feedstock comprising a hydrocarbon resin or rosin, under suitable hydrotreating conditions, with a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals and wherein the ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10. The process according to the invention can achieve increased hydrocarbon resin productivity through increase in throughput volumes and effective catalyst lifetimes. The process of the invention is desirably practiced with a bulk catalyst consisting of only the combination of the metal species with the active metal components. The absence of carrier substrates largely removes the possibility of halogen accumulation on substrate surfaces that, in turn, can acidify metal catalysts such that additional, progressive cracking of the hydrocarbon resin molecules occurs.

  • Patent number: 6726836
    Abstract: A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted hydrocarbon fuel stock supply which is used to power a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like; or in a stationary environment. The power plant hydrogen fuel source can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, thiophenes and the like. The undiluted hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the now desulfurized hydrocarbon fuel supply continues through the remainder of the fuel processing system. The method involves adding hydrogen to the fuel stream prior to the desulfurizing step. The method can be used to desulfurize either a liquid or a gaseous fuel stream.

    Abstract: A process for the production of white oil includes adding a supercritical fluid (propane, butane or carbon dioxide) to the base oil and hydrogen injected into a reactor for hydrogenation. The base oil and supercritical fluid use high-pressure injector pumps as the feed system. The feed system for hydrogen uses a high-pressure compressor to compress hydrogen from a hydrogen tank to a storage tank, then a mass flow controller is used to steadily feed the hydrogen. A static mixer mounted in line, upstream from the inlet of the reactor mixes the reactant well. Several thermocouples are connected to the reactor, inlet and outlet of said reactor to measure the temperatures of the reaction. The detected data from the thermocouples are transferred to a six-point thermograph. The pressure of the reaction is maintained by a back pressure regulator that is mounted downstream from the outlet of said reactor. After the hydrogenation reaction is complete, the pressure of the fluid in the outlet of the reactor is reduced.

  • Patent number: 6444118
    Abstract: A process for concurrently fractionating and treating of a full range naphtha stream. The full boiling range naphtha stream is first subjected to simultaneous thioetherification or selective hydrogenation and splitting into a light boiling range naphtha, an intermediate boiling range naphtha and a heavy boiling range naphtha. The intermediate boiling range naphtha containing thiophene and thiophene boiling range mercaptans, dienes or mixtures may be subjected to a second thioetherification or selective hydrogenation, depending on its make-up, and then passed on to a polishing hydrodesulfurization reactor or the entire intermediate stream may be passed directly to the polishing reactor. The bottoms are subjected to concurrent hydrodesulfurization and fractional distillation and the combined overheads and bottoms are fed to the polishing reactor.

  • Patent number: 6428686
    Abstract: A process where the need to circulate hydrogen through the catalyst is eliminated. This is accomplished by mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is “high” relative to the oil feed. The type and amount of diluent added, as well as the reactor conditions, can be set so that all of the hydrogen required in the hydroprocessing reactions is available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required, therefore, hydrogen recirculation is avoided and trickle bed operation of the reactors is avoided. Therefore, the large trickle bed reactors can be replaced by much smaller tubular reactor.

  • Patent number: 6425998
    Abstract: A process for using a hydrogen sensor in a liquid metal heat exchange loop in a hydrocarbon conversion process with high hydrogen permeation. The hydrogen sensor of the present invention consists essentially of a hollow nickel membrane probe in intimate contact with liquid metal. A vacuum chamber in fluid communication with the hollow nickel membrane probe through which hydrogen permeates, wherein the vacuum chamber is initially evacuated to a vacuum pressure and is in equilibrium with the vacuum chamber. The hydrogen sensor is useful for measuring the partial pressure of the hydrogen in the liquid metal to provide advisory control for the removal of hydrogen from the liquid metal exchange loop to avoid the problem of metal hydride formation and associated plugging problems.

  • Patent number: 6420619
    Abstract: The C3 to C6 cut from a cracking process containing propylene, butane, 1-butene, 2-butene and acetylenic and diene components including butadiene are preferentially converted to propylene. The cut is simultaneously fractionated and catalytically hydrogenated to hydrogenate the acetylenic and diene components. The fractionation and subsequent separation recovers a C4 component comprising a mixture of isobutene, 1-butene and 2-butene. This C4 component is then further simultaneously fractionated and catalytically hydrogenated and hydroisomerized to hydrogenate remaining butadiene, remove isobutene overhead and convert 1-butene to 2-butene leaving a bottoms of 2-butene. The 2-butene is then injected with ethylene and catalytically metathesized to form propylene.

  • Publication number: 20020074262
    Abstract: A diesel fraction is purified by a process having two reaction stages and a stripping stage in a single vessel. Heteroatoms are removed in the first stage, to permit the use of a sulfur sensitive aromatics saturation catalyst in the second stage, to produce a purified diesel stock. The first stage liquid effluent is stripped in a stripping stage and then passed into the second reaction stage, in which it reacts with fresh hydrogen for aromatics removal. The second reaction stage produces a hydrogen-rich vapor effluent, which may provide all or a portion of the first stage reaction hydrogen. A noble metal catalyst is employed in the second stage. The diesel feed for the process may be one that has been at least partially refined with respect to either or both heteroatom or aromatics removal.
