The invention relates to a device for filling a container with solid particles, the device having annular ducts for passing particles, which ducts are defined by a plurality of vertical nozzles arranged coaxially relative to one another, and a diaphragm arranged upstream from the annular ducts for regulating the flow rate of particles in the annular ducts, the diaphragm has a plurality of shutter flaps for shutting off the annular ducts, each flap shutting off an angular sector of a single annular duct and the diaphragm having control means for controlling movement of the shutter flaps that are configured to be capable of partially shutting off any one of duct independently of the other ducts. The invention also relates to a method of shutting off a filler device.

The invention relates to a system for determining relief on a granule filling surface in a petrochemical reactor, the filling direction in which the reactor is filled defining a vertical direction, the reactor having a central vertical axis, the system including a transmitter configured to be positioned above the filling surface in such a manner as to transmit a signal to various points of said surface. The system includes shift means for shifting the transmitter about the central axis of the reactor through an angle that is great than 60&#xb0;.

A body (), feeding a group of enlarged pipes () in which straight pipes () slide so as to control the discharge of particles. At the exit of these tubes, the particles are propelled towards the periphery by gas jets that originate from perforated tubes (). A rotating set of plates () whose periphery is fitted with brushes () having bristles of various dimensions, scatters the particles in such a way so as to distribute them uniformly according to a horizontal plane. A correcting device (and) that gets its feed of particles from the top of the device enables to set right any mal-distribution by directing an additional partial flow of particles towards an area where the height of the bed is low or uneven. Such a machine can also be used for the loading of silos or of catalytic reactors.

A cylindrical reactor containing a radial particle bed suitable for hydrocarbon reforming comprises: a reactor inlet () having a means of feeding a charge, numerous perforated, internal conduits () arranged around the periphery of the reactor and parallel to the axis of the reactor, which feed particle bed () with the charge, a circular collar () supporting the conduits in the lower bottom of the reactor, a perforated () central collector () receiving a reactor effluent connected to an outlet (). Collar () is perforated with openings () plumb with each conduit () and it comprises a vertical, circular grate () that is perforated with holes () impervious to particles and is suspended on the collar so as to delimit, with the wall of the reactor, a ring-shaped chamber () for circulation of the charge, the height of the grate being adjusted so that it delimits an internal passage between the grate and the bottom of the reactor, which is made impervious to particles by a fabric whose upper part is attached to the grate and whose lower part rests on the bottom of the reactor.

Increased capacity reactor and its use

A device for de-dusting, i.e., removing dust, from a particle flow in an enclosure. The device is optionally associated with a unit for dense loads which supplies the particle flow. The device is useful, for example, for removing dust from catalyst particle flows and from adsorbent particle flows. It is also useful for removing dust from grain or cereal particles, for example, being supplied to a silo.

A process for discharging solids from a vessel having at least three successive beds of solid particulate material with at least two of the beds being of different solid material than the other. The process comprises opening a lowermost closure and discharging the lowermost bed from the vessel while maintaining other closures in closed positions. After discharging the lowermost bed, opening the next-to-lowermost closure to permit the next-to-lowermost bed of solids to replace the lowermost bed, and repeating this operation up through all the beds without mixing of the beds, and discharging each bed separately from the vessel.

Enclosure containing several beds of solid material separated and

An apparatus for filling a receptacle with a divided solid product, comprises a feeder hopper and a dispersion head. The dispersion head includes a series of parallel and coaxial plates superimposed on one another wherein the surface area of the plates diminishes from the top plate down to the bottom plate. The whole assembly is devised such that each plate includes an aperture which allows gravity feed to the plate situated immediately underneath. The lower plate may include an aperture in order to feed the center of the receptacle. The plates are rotated to permit ejection of divided solids by centrifugal force. At least one of the plates has apertures and is placed at the exit of the hopper and in front of the particle distribution plates.

The invention relates to a reactor for carrying out gas phase chemical reactions and having at least one compartment (8) incorporating a catalytic lining (31) in which radially circulates at least one gas. As the upper wall (32), it has at least one layer (19) of at least one flexible material such as a tight, inert, refractory material fabric. This fabric optionally cooperates with a first layer of balls (12) resting on the fabric. It is placed on the biller (31) in such a way that it completely covers the latter. The reactor is used in the reforming of fuels.

The present invention provides a burner for the partial oxidation under pressure of a first fluid by the second fluid. This burner comprises two fluid introduction tubes, one being internal to the other, with each of the tubes comprising a plate, and with each plate having several holes and a plate of the external tube has holes placed opposite the holes in the internal plate.
