  • Patent number: 7951346
    Abstract: Methods and systems for reducing emissions of particulate matter from a gaseous stream are provided. The subject systems include a catalyst that reduces the amount of particulate matter emissions in the gaseous stream. Embodiments of the subject systems may also reduce the amount of particulate matter precursor emissions in the gaseous stream. In some cases, the subject systems and methods include a sorber that facilitates the reduction in particulate matter and particulate matter precursors in the gaseous stream. The subject methods and systems find use in a variety of applications where it is desired to reduce particulate matter emissions from a gaseous stream.

  • Patent number: 7951341
    Abstract: A moving bed of catalyst loses activity as it moves through the reactor. Creating multiple passes for the process fluid moving across a catalyst bed, increases the utilization of the catalyst and creates a pseudo-counter current flow of catalyst and process fluid. The flow improves the temperature profile of the bed and allows higher temperature fluid contacting the less active catalyst.

    Abstract: Alkylation systems and processes are provided herein that include a slurry reactor. The slurry reactor receives a reactor feed slurry including catalyst and liquid isobutane, a olefin feed, and a circulating reactor vapor stream, where the slurry reactor produces a reactor liquid effluent stream, the reactor liquid effluent stream including catalyst, isobutane, and a liquid alkylate product. The catalyst in the reactor feed slurry can be regenerated catalyst from a catalyst regenerator. The catalyst can be regenerated after being removed from the liquid alkylate product and isobutane in the reactor liquid effluent stream.

  • Patent number: 7875253
    Abstract: An object of the invention is to provide a decomposing system for polyisocyanate residues that is capable of suppressing reaction of polyisocyanate residues with high temperature and high pressure water to allow smooth start-up of the operation, and a start-up method for the decomposing system for the polyisocyanate residues. The decomposing system is used for hydrolyzing the polyisocyanate residues to polyamine using high temperature and high pressure water, comprising a hydrolyzer, a water feed pipe connected to the hydrolyzer, a residual feed pipe connected to the water feed pipe, a solvent feed line for filling an organic solvent in a solvent filling portion of the residual feed pipe, and a solvent draining line. Upon start-up of the operation, the organic solvent is previously filled in the solvent filling portion via the solvent feed line and the solvent draining line, first, and then, the high temperature and high pressure water is fed from the water feed pipe to the hydrolyzer.

  • Patent number: 7828864
    Abstract: Systems and methods for producing hydrogen gas with a fuel processing system that includes a hydrogen-producing region that produces hydrogen gas from a feed stream and a heating assembly that consumes a fuel stream to produce a heated exhaust stream for heating the hydrogen-producing region. In some embodiments, the heating assembly heats the hydrogen-producing region to at least a minimum hydrogen-producing temperature. In some embodiments, the feed stream and the fuel stream both contain a carbon-containing feedstock and at least 25 wt % water. In some embodiments, at least one of the feed and fuel streams contain at least one additional component. In some embodiments, the feed and fuel streams have the same composition. In some embodiments, the feed and fuel streams are drawn or obtained from a common source or supply, and in some embodiments as a liquid stream that is selectively apportioned to form the feed and fuel streams.

  • Patent number: 7807116
    Abstract: A shell-and-tube reactor is disclosed. Contact tubes are disposed within a cylindrical housing and are secured to tube plates. Gas and liquid phases are received via a feed opening in a lower end cap and discharged via an upper end cap in the housing. A distributor device is disposed in the housing, such that the tube plates serve as a horizontal plate for the distributor device to back up the gas phase and form a gas cushion, and vertical elements extend from the contact tubes. The vertical elements are adapted to conduct the liquid phase, are open in the upstream direction, and project outward in the direction of the feed opening through the gas cushion. The vertical elements further include at least one first opening on the circumference for the gas phase and at least one second opening for the liquid phase.

  • Patent number: 7780928
    Abstract: An improved radial or cross flow moving bed regenerator or reactor, in which the solid particle residence time in the vessels can be changed in different section of the regenerator or reactor. The improvement results from the placement of one or multiple screen inserts which divides the radial or cross flow bed into separate solid flow channels. The residence time of the solid in each solid flow channels are optimized based on the regeneration or reaction requirement by changing the location, orientation and geometry of the screen inserts. As a result of the optimization of solid residence time in different section in the radial flow bed, the efficiency of a regenerator or a reactor is improved.
