A device and method for cleaning producer gas includes a filter bed housing and a microwave chamber. The filter bed housing comprises an inlet for carbon-based material and a spent carbon outlet. The microwave chamber comprises a permeable top and wave guides around the perimeter through which microwaves can be introduced into the device using magnetrons. The method comprises using the device by filling the filter bed housing with carbon-based material, introducing microwaves into the microwave chamber using the magnetrons and wave guides, passing the gas through carbon-based material in the filter bed chamber, the microwave chamber, the gas permeable top and the gas outlet.

The invention provides an improved system for separation technology intended to reduce unwanted catalyst/thermal reactions by minimizing contact of the hydrocarbons and the catalyst within the reactor.

A system and process for carrying out one or more chemical reactions are provided and include one or more chemical reactors having particulate solids forming a bed therein, and a gas stripping zone forming a non-mechanical seal between said reactors which includes a conduit connecting the reactors. The conduit includes an inlet for a stripping gas which is adapted to prevent process gas from passing between reactors while permitting particulate solids to pass between reactors.

A catalyst loading system comprising: a vessel comprising at least one gas distribution nozzle at or near the bottom of the vessel, a top fluid distributor located at or near the top of the vessel, a catalyst inlet through which catalyst is introduced into the vessel, a first contact point at which catalyst introduced into the vessel first contacts the contents of the vessel, and a discharge outlet whereby catalyst exits the vessel. Methods of preparing catalyst slurry for introduction into a downstream reactor or in-situ activation within the vessel utilizing the catalyst loading system are also disclosed.

A system for converting fuel may include a first moving bed reactor, a second reactor, and a non-mechanical valve. The first moving bed reactor may include at least one tapered section and multiple injection gas ports. The multiple injection gas ports may be configured to deliver a fuel to the first moving bed reactor. The first moving bed reactor may be configured to reduce an oxygen carrying material with a fuel by defining a countercurrent flowpath for the fuel relative to the oxygen carrying material. The second reactor may communicate with the first moving bed reactor and may be operable to receive an oxygen source. The second reactor may be configured to regenerate the reduced oxygen carrying material by oxidation.

A method for managing the charging of a space with solid particles, comprising: modelling an expected charging profile over a charging duration, during the charging, receiving, from at least one sensor, measured values of a parameter indicative of the height of a bed of solid particles charged into the space, determining filtered values of the parameter indicative of the height from the measured values received and from the modelled charging profile, and transmitting the filtered values to control the charging with solid particles.

A float valve for a chemical reactor has a central pipe which glides around a liquid transfer pipe when a liquid level rises and falls, thereby opening for fluid transfer through liquid transfer apertures in the transfer pipe when the liquid level is rising and shutting off for fluid transfer when the float lowers and seals against a sealing ring placed on the transfer pipe below the liquid transfer apertures.

A gas production device that makes it possible to raise the temperature of a reaction unit by separating a removal unit from a reactor. The device has at least two reactors and a removal unit. The two reactors are connected in series and are configured to supply an oxidizing gas containing carbon dioxide, and a reducing gas containing a reducing substance. Each of the reactors accommodates a metal and/or a metal oxide which promotes reduction of the carbon dioxide or the reaction between the carbon dioxide and the reducing substance, thereby generating a valuable carbon substance. The removal unit is connected between the two reactors and has a phase separation mechanism that carries out phase separation of a gaseous component and a separated component including at least one of a liquid component and a solid component produced through cooling, thereby removing products derived from the gas supplied to the reactors.

A system for contacting gases and liquids includes a vessel containing inert particles, wherein the total volume of the inert particles is from 1 to 20% of the total working volume of the vessel.
