摘要:
A process for translating objects a resonating chamber is described. The process includes: (i) obtaining a resonating chamber filled with a fluid medium and objects disposed therein; and (ii) generating one or more different standing waves to convey said objects from their disposed position to another location inside the resonating chamber. Using the above-described translating process, the objects may be positioned at a cavitation zone inside the resonating chamber. In one aspect of the present teachings, the objects are then subject to acoustic cavitation to convert at least some of the objects from one state to another state.

Mechanically fluidized systems and processes allow for efficient, cost-effective production of silicon. Particulate may be provided to a heated tray or pan, which is oscillated or vibrated to provide a reaction surface. The particulate migrates downward in the tray or pan and the reactant product migrates upward in the tray or pan as the reactant product reaches a desired state. Exhausted gases may be recycled.

The invention relates to a process for incorporating sulfur in the porosity of the solid particles of a catalyst for the conversion of hydrocarbons or an adsorbent. This process is carried out off-site in the presence of hydrogen sulfide that is pure or diluted in hydrogen or nitrogen, a process in which said particles are made to rise or fall in a sulfur incorporation zone that comprises at least one vibratory helical coil that is essentially tubular in shape and that comprises at least two turns, whereby said particles are subjected to a temperature profile over the majority of their path in said coil and whereby said particles are brought into contact with at least one fluid on at least one portion of their path.

This invention relates to a sonic device (and a method) for enhancing a process involving a solid object and a gas, where the gas surrounds the object or at least is in contact with a surface of the object, the device comprising sonic means for applying a high intensity sound or ultrasound to at least the surface of the object, wherein the high intensity sound or ultrasound, during use of the sonic device, is applied directly in the gas that is also the medium through which the high intensity sound or ultrasound propagates to the surface of the object, whereby a laminar sub-layer at the surface of the object is reduced and/or minimized. The reduction of the laminar sub-layer provides increased heat transfer efficiency and/or increased catalytic speed and/or increased gas exchange.
摘要:
A method of producing decabromodiphenyl alkanes includes the steps of charging a reaction vessel with bromine and a bromination catalyst and introducing a diphenyl alkane into the vessel at a location above the level of the charge bromine and catalyst. A dip tube apparatus for introducing the diphenyl alkane includes an inner tube and an outer tube, each of which are disposed above the surface of the bromine reaction vessel. The inner tube is fitted with a plug having an opening. Diphenyl alkane flows through the inner tube, out the opening in the plug, and into the reactor. The outer tube is disposed around and along the inner tube. Reaction mass from the vessel is recirculated from the vessel, through the outer tube and back to the vessel so as to form a curtain of reaction mass around the stream of diphenyl alkane being simultaneously fed into the reaction vessel.

It is possible to activate a physical reaction and/or a chemical reaction in a medium, comprising a solution and solid matter that is freely dispersed in said solution, by placing the mixture in a reactor that has two walls which are located opposite close to each other, whereby the mixture fills the space in between the two walls and forms therein a thin long layer in a direction that is defined by a geometrical axis parallel to the walls, by activating an agitating means that are disposed outside the reactor and capable of acting through said walls on an area of agitation covering part of the layer and having a small dimension in the direction of the geometrical axis, and by simultaneously displacing said agitating means in such a way that the area of agitation substantially spans the entire area located between the two walls.
摘要:
A method and an apparatus for performing a continuous reaction with at least one liquid reaction phase incorporating at least one starting compound in the presence of at least one solid-phase catalyst, wherein the phases to be contacted are circulated through at least one pulsed reaction column (1). The liquid reaction phase is continuously fed into the middle or lower portion of the pulsed column (1), the liquid phase is circulated upwards through the pulsed column (1), and a counterflow made up of lumps (9) of a solid selective extraction compound is continuously circulated. Furthermore, each solid catalyst is continuously circulated through the pulsed column (1) in contact with the liquid phase.
