Abstract:
An apparatus may include a mud pot and a reflectometer to monitor a level of an interface between liquid diluent and catalyst slurry in the mud pot using reflectometry. The apparatus may include a mixing tank and a conduit to transfer catalyst slurry from the mud pot to the mixing tank. The apparatus may include a polymerization reactor and a conduit to provide catalyst slurry from the mixing tank to the polymerization reactor.
Abstract:
A two-stage reactor is disclosed for the conversion of solid particulate biomass material. The reactor is designed to maximize conversion of the solid biomass material, while limiting excess cracking of primary reaction products. The two-stage reactor comprises a first stage rector, in which solid biomass material is thermally pyrolyzed to primary reaction products. The primary reaction products are catalytically converted in a second stage reactor.
Abstract:
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.
Abstract:
The invention relates to a device for loading solid particles into a vessel comprising: particle feed means (24); means (26) for dispersing the particles from the top to the bottom of the vessel; at least one means (17) for measuring the height of the filling bed; and at least one automated system for controlling the feed means (24) and/or the dispersion means (26), and also to a process and uses implementing the device.
Abstract:
Systems for loading catalyst and/or additives into a fluidized catalytic cracking unit are disclosed. Methods of making and using the systems are also disclosed.
Abstract:
A riser reactor system comprising a riser reactor and a catalyst feed device for fluidized catalyst, the riser reactor having a riser interior in which catalyst is flowing during normal operation, and the feed device comprising an annular trough surrounding the riser interior, the annular trough having an upstream opening for receiving fluidized catalyst, and at least one substantially circumferential downstream opening providing fluid communication between the trough and the riser interior; and a process for the preparation of an olefinic product using a riser reactor system as claimed in any one of the preceding claims, the process comprising reacting an oxygenate feedstock in the presence of an oxygenate conversion catalyst under oxygenate-to-olefin conversion conditions in the riser reactor system, to obtain the olefinic product.
Abstract:
Reactors for the pyrolysis of pyrolyzable matter, pyrolysis systems incorporating the reactors and methods of using the reactors are provided. Also provided are systems and methods for integrating the pyrolysis and hydrodeoxygenation of pyrolyzable matter. The pyrolysis reactors create a horizontally rotating, fluidized-bed to which pyrolyzable matter, such as biomass, may be converted via pyrolysis into liquid fuels and/or value-added chemicals.

Abstract:
A process for charging a reactor with a fixed catalyst bed which comprises at least one annular shaped support catalyst body K, in which, before the charging, fragments formed in the preparation of the shaped catalyst bodies K are removed by screening.
Abstract:
Polymer powder vessel having a silo including a main vertical cylinder and a hopper at the bottom of the cylinder, a polymer powder which occupies the full volume of the hopper and at least a part of the volume of the cylinder, a polymer powder silo inlet pipe connected to the silo at a height located above the polymer powder, and a polymer hopper withdrawal pipe is also connected to the hopper. The polymer powder hopper withdrawal pipe is also connected to the silo at a location above the polymer powder for recirculating a part of the polymer powder within the silo.
