Method for gas-solid contacting in a bubbling fluidized bed reactor

The present invention relates to a method for gas-solid contacting in a bubbling fluidized bed reactor by:(a) introducing into a reactor with bed length to bed diameter ratio below about 5.0, a primary gas consisting essentially of reactant(s) of the reaction to be carried out in the bed of solid particles through a primary gas distributor located at the reactor bottom at a superficial gas velocity Up, which is very close or equivalent to the minimum fluidization velocity Umf, required for achieving the incipient fluidization of the solid particles in the bed to obtain an emulsion phase consisting essentially of the solid particles and the primary gas with little or no formation of gas bubbles to achieve incipient fluidization or liquid-like behavior of fluidizable solid particles;(b) forming gas bubbles in the incipiently fluidized bed by introducing through a secondary gas distributor located immediately above the primary gas distributor a secondary gas, selected from one of the reactants which is used in excess of that required for the reaction stoichiometry, steam, an inert or a mixture of two or more thereof at a superficial gas velocity, Us, which is related to the superficial velocity of the primary gas such that a ratio of the superficial velocity of the secondary gas to the superficial velocity of the primary gas Us / Up, is in the range from about 0.5 to about 10.0, preferably from about 1 to about 5.

One-part non-toxic spray foam

InactiveUS20080281006A1Reduce manufacturing costWorker safetyWaxFoaming agent
A one-part spray foam formed by Michael addition chemistry is provided. The foamable composition includes at least one electron donor, at least one electron acceptor, an encapsulated catalyst, and one or more blowing agents. The catalyst is a weak or strong base. The encapsulation of the catalyst controls the polymerization of the Michael addition compounds such that the catalyst can be added and / or activated at a desired time to begin the foaming reaction. The catalyst may be encapsulated in a high molecular weight inert polymer or wax. In some embodiments, the chemical blowing agent(s) are also encapsulated. To produce a foam according to the invention, a single stream of the foamable composition is fed into an application gun where the slurry is heated and mixed. The heat and / or mixing in the gun releases the catalyst, which initiates the reaction between the Michael donor and Michael acceptor to form the foam.

Separation of hydrocarbons from hydrocarbon containing liquid

A novel filtration media employing polymeric absorbents comprising a material selected from the group consisting of styrene, pentadiene, cyclopentadiene, butylene, ethylene, isoprene, butadiene, propylene and mixtures thereof; and a filtration enabler intimately mixed with the polymeric absorbent. Preferably, the filtration enabler comprises clay, ground glass, talc, mica, recycled rubber, sand, gravel, vermiculite, recycled plastic chips, an inert, non-absorbent material, or mixtures thereof. Preferably, the polymeric absorbent may be further compounded to incorporate about 10 to 50% recycled or waste plastic scrap, scrap polyolefins, inorganic fillers, or other inexpensive, relatively inert solids. Other compounding materials may include clay, talc, mica, ground glass, silica, and mixtures thereof. Upon contact with a hydrocarbon containing liquid, the liquid partially dissolves the polymeric absorbent forming a partial filtration barrier prior to the filtration media substantially absorbing the hydrocarbons, and allowing hydrocarbon-free liquid to flow through the filtration media. In situations of a leak or spill wherein an excess of hydrocarbons are present, the filtration media forms a plug to seal and prevent further discharge of the hydrocarbons. The filtration media may be placed inside a portable container for insertion into an existing drain such that hydrocarbon containing liquid is filtered through the device allowing hydrocarbon-free liquid to flow from the device. The filtration media has a thickness within the container adapted to substantially filter out hydrocarbons while capable of forming a plug in an excess of hydrocarbons. The filtration media of the present invention may be employed in pits, pipes, and self-contained cartridges of various sizes to remove and contain hydrocarbons from a hydrocarbon containing liquid or a hydrocarbon spill or leak, and that the absorbent will form a plug in an excess of hydrocarbons entering the pit, pipe or cartridge. Also described are methods of filtering and preventing discharge of a hydrocarbon containing liquid.

System to continuously produce carbon fiber via microwave assisted plasma processing

A system to continuously produce fully carbonized or graphitized carbon fibers using microwave-assisted plasma (MAP) processing comprises an elongated chamber in which a microwave plasma is excited in a selected gas atmosphere. Fiber is drawn continuously through the chamber, entering and exiting through openings designed to minimize in-leakage of air. There is a gradient of microwave power within the chamber with generally higher power near where the fiber exits and lower power near where the fiber enters. Polyacrylonitrile (PAN), pitch, or any other suitable organic / polymeric precursor fibers can be used as a feedstock for the inventive system. Oxidized or partially oxidized PAN or pitch or other polymeric fiber precursors are run continuously through a MAP reactor in an inert, non-oxidizing atmosphere to heat the fibers, drive off the unwanted elements such as oxygen, nitrogen, and hydrogen, and produce carbon or graphite fibers faster than conventionally produced carbon fibers.

Method for electrowinning of titanium metal or alloy from titanium oxide containing compound in the liquid state

This invention relates to a method for electrowinning of titanium metal or titanium alloys from electrically conductive titanium mixed oxide compounds in the liquid state such as molten titania slag, molten ilmenite, molten leucoxene, molten perowskite, molten titanite, molten natural or synthetic rutile or molten titanium dioxide. The method involves providing the conductive titanium oxide compound at temperatures corresponding to the liquid state, pouring the molten material into an electrochemical reactor to form a pool of electrically conductive liquid acting as cathode material, covering the cathode material with a layer of electrolyte, such as molten salts or a solid state ionic conductor, deoxidizing electrochemically the molten cathode by direct current electrolysis. Preferably, the deoxidizing step is performed at high temperature using either a consumable carbon anode or an inert dimensionally stable anode or a gas diffusion anode. During the electrochemical reduction, droplets of liquid titanium metal or titanium alloy are produced at the slag/electrolyte interface and sink by gravity settling to the bottom of the electrochemical reactor forming, after coalescence, a pool of liquid titanium metal or titanium alloy. Meanwhile carbon dioxide or oxygen gas is evolved at the anode. The liquid metal is continuously siphoned or tapped under an inert atmosphere and cast into dense and coherent titanium metal or titanium alloy ingots.
