A system and a method for a constant micro dosing of powder material include a control device, a cylinder with a first opening and a piston movably arranged inside the cylinder and controllable by the control device. The piston is movable in the direction to or away from the first opening along a piston stroke direction. The cylinder stores the powder material between the piston and the first opening. The piston pushes the powder material through the first opening by moving along the piston stroke direction. Further the system and the method include a removing device for removing the powder material which is pushed out of the first opening of the cylinder. The control device controls the piston and the removing device in a synchronized manner such that a predetermined amount of powder material pushed through the first opening is removable by the removing device.

The invention relates to a filling system (1) for a container intended to store solid particles, the system (1) being arranged to cooperate with a supply device for feeding solid particles and comprising a device (5) for distributing the solid particles, which has at least one separator element (9) intended to receive and selectively distribute the solid particles toward a dispensing device (7), the separator element (9) comprising a receiving body (11) for receiving solid particles, one end of which has an axial opening (13) for continuously feeding the dispensing device (7), the dispensing device (7) comprising at least one scattering element (21) for homogeneously filling the container with solid particles, which is driven by a drive shaft passing through the axial opening (13). According to the invention, the receiving body (11) comprises a frustoconical part (11a) which has the axial opening (13) and flares away from the axial opening (13), the frustoconical part (11a) being extended by a tubular part (11b) comprising at least one radial opening (15) which is located upstream of the axial opening (13) and is arranged to direct the solid particles without encountering those exiting the axial opening (13) before arriving in the dispensing device (7) from a predetermined amount of solid particles stored in the frustoconical part (11a) of the receiving body (11) in order to guarantee a minimum flow of solid particles even in the event of variations in the flow rate of the supply device.

A device and method for loading pellets. A funnel includes a means for loading pellets into a reactor tube, and a means for quickly and easily measuring the elevation of pellets in the reactor tube while the reactor tube is being loaded. A vacuum-assist device may be used to pick up and transfer a desired volume of porous pellets while removing dust from the porous pellets.

A particular embodiment of the invention relates to a conveyor system (10) for conveying material (for example: particulate material such as a catalyst) from a particular storage area (such as drum (18)) to a second location (such as a reactor (13)). In accordance with the present embodiment of the invention, the conveyor system (10) is adapted to isolate from the environment the particular material to be conveyed; thus, avoiding that the particular material enters in contact with, for example, the atmosphere. Isolating the particular material is particular advantageous; because, for example, the isolation process suppresses activation of the material (such as the catalyst) due to coming in direct contact with the oxygen and moisture content of the atmosphere.

The present invention relates to a three-phase reactor for the reaction of a hydrocarbon feedstock with hydrogen and to a hydroconversion process, for example of H-Oil™ type, employing it, comprising a chamber with an upper end and a gas/liquid separation device comprising: a recycle cup, above the catalytic reaction zone and delimiting, with the upper end, a recycle zone, comprising a cylindrical upper part extended by a lower part of decreasing section and of variable angle of inclination, provided with vertical pipes for the passage of a gas/liquid mixture originating from a catalytic reaction zone, and having a fixed angle of inclination β of between 50° and 85° with respect to the axis of the cylindrical part, a pipe for recycle of the liquid at the apex of the lower part, in fluidic communication with the lower end of the chamber by recirculation means.

A system for vibrational loading is provided. The system includes: one or more pilot plant reactor tubes; at least one vibrator attached to and configured to impart vibrational energy to a corresponding at least one of the reactor tubes during the vibrational loading; and a portable reactor loading station. The loading station includes: a base structure; a plurality of rolling members attached to the base structure which is configured to contact and roll across a horizontal surface while remaining attached to the base structure and separate the base structure from the horizontal surface; a frame attached to and extending vertically from the base structure; and one or more clamps attached to the frame to secure the reactor tubes in a vertical orientation. The clamps are attached to the frame through corresponding elastomeric members vibrationally isolating the secured reactor tubes from the frame during the vibrational loading.

A device for loading pellets into reactor tubes includes a portable loading box with a bottom wall defining an opening, a loading tube projecting downwardly from the opening, and a movable dam for dividing said loading box into separate chambers.

A continuous feeding process and device for waste flexible polymer material; wherein the process continuously feeds waste flexible polymer material into a subsequent pyrolysis apparatus following compression, cutting and dispersion; the waste flexible polymer material is pre-treated during compression, cutting and dispersion to achieve continuous sealing feeding, while pyrolysis oil gas preheats and self-lubricates the device; the device used includes a feeding apparatus, a material dispersion apparatus and a screw feeder; the material is compressed, cut and dispersed in the feeding apparatus and the material dispersion apparatus, and then falls into the screw feeder, being preheated and thermally sealed by the pyrolysis oil-gas in the screw feeder; by using such a process, waste flexible polymer material from various sources may be continuously fed for pyrolysis, fully using the temperature of an oil-gas generated in a pyrolysis machine for preheating and device lubrication.

The invention relates to a filling system (1) for a container for storing solid particles, comprising a distribution device (5) for solid particles for receiving and selectively distributing the solid particles towards a dispensing device (7), and comprising at least one divider element (11), the dispensing device (7) comprising at least one scattering element (13) for homogeneously filling the container with solid particles, the divider element (11) being rotatably mounted about an axis substantially parallel to the direction of flow of the stream of solid particles in order to allocate any defect in the flow of the solid particles in the distribution device (5).
