Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

A bayonet reactor including a catalytic reactor in the form of an annular structured packing is provided with increased surface area for the transfer of heat between annulus gas and return gas, an increased coefficient of heat transfer between the annulus and return gases, and a reduced overall pressure drop relative to conventional reactors. The reactors of the present technology can enable intensified catalytic processing.

A continuous flow catalytic reactor, an assembling method therefor and an application thereof includes a reaction vessel, a filler packaged in the reaction vessel and a charged catalytic component; the charged catalytic component is fixed to the filler under an action of a direct-current electric field. The continuous flow catalytic reactor may be applied to continuous flow reactions such as a monosaccharide epimerization reaction. A monosaccharide epimerization reaction method includes: providing the continuous flow catalytic reactor; electrically connecting the continuous flow catalytic reactor with a direct-current power supply, thereby to forming the direct-current electric field by electrically connecting the continuous flow catalytic reactor with the direct-current power supply; and heating a reactor container to a target temperature, and inputting a monosaccharide solution from a liquid flow inlet of the reaction vessel and then collecting a solution containing a target product from a liquid flow outlet of the reaction vessel.

A reactor tank is provided having an enzyme inlet, a heating jacket positioned around the exterior center of the tank, a gas outlet for communicating with a vacuum apparatus to create a vacuum within the reactor tank and for communicating with a condensing unit, a first gas inlet for receiving gas from a feed tank and a first liquid outlet for recirculating the liquid from the first liquid outlet back to the feed tank. The reactor tank further includes a sparged unit and a screen positioned within the tank between the sparged unit and the first liquid outlet, where the sparged unit is connected to the first gas inlet for receiving gas from the feed tank. The reactor tank is utilized in a reactor system further including a condensing unit, vacuum pump or venturi valve, a first feed tank connected to the first gas inlet, a coalescer having at least one circulation pipe and a first circulation pump connected to the first liquid outlet for circulating a portion of the liquid dispelled from the liquid outlet to the coalescer, which after being filtered through coalescer is recirculated through circulation pipe back to the first feed tank.

An object of the present invention is to prevent stress-corrosion cracking of a header (40) of a reactor. A reactor for producing trichlorosilane by causing metal silicon powder and a hydrogen chloride gas to react with each other includes a cooler (70), the cooler including a plurality of heat transfer medium pipes (30) and a header (40), the plurality of heat transfer medium pipes being provided in a fluid bed (60) inside the reactor, the header being provided in a freeboard section (50) inside the reactor, the header being comprised of a corrosion-resistant material.

Slurry hydrocracking processes are described. The methods include hydrotreating a heavy residual hydrocarbon feed in a hydrotreating zone under residual hydrotreating conditions to form a hydrotreated effluent. The hydrotreated effluent is separated in an first separator to form an overhead vapor stream and a bottoms stream. The bottoms stream is hydrocracked in a slurry hydrocracking zone under slurry hydrocracking conditions. The effluent from the slurry hydrocracking zone is fractionated in a fractionation zone into at least two streams. Slurry hydrocracking apparatus is also described.

Methods and systems for recovering a hydrocarbon from fluid catalytic cracking (FCC) slurry and for separating a FCC slurry stream from a FCC effluent are provided. An exemplary hydrocarbon recovery method comprises the steps of: contacting a feed with a catalyst in a FCC reactor under conditions suitable to crack one or more hydrocarbons and generate a FCC effluent; separating the FCC effluent with a fractionation column to generate a product stream and a FCC slurry that collects in a lower portion of the fractionation column; drawing a first FCC slurry stream at a first temperature from a first location in the fractionation column; drawing a second FCC slurry stream at a second temperature from a second location in the fractionation column, and separating a hydrocarbon from the second FCC slurry stream, wherein the second temperature is higher than the first temperature.
