A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.

The present disclosure is further directed to reactor modules for use with the above steam reformers and methods of producing a hydrogen reformate.

This invention relates to processes and systems for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons and/or aromatics, for example converting acyclic C.sub.5 hydrocarbons to cyclopentadiene in a reactor system. The process includes heating an electrically-conductive reaction zone by applying an electrical current to the first electrically-conductive reaction zone; and contacting a feedstock comprising acyclic hydrocarbons with a catalyst material in the electrically-conductive reaction zone under reaction conditions to convert at least a portion of the acyclic hydrocarbons to an effluent comprising alkenes, cyclic hydrocarbons, and/or aromatics.

The present invention consists in a reactor, a system and a method to process products such as polymers, where the reactor is formed by a vertical structure made up by a concentric ferrous inner tank and an external tank opened by the lower end, between which a jacket is arranged, where said reactor comprises: an upper lid; at least an inlet for material; an overhead valve in the at least inlet duct for material; at least one chimney; a stirring unit comprising a vertical axis connected to: a plurality of main blades fixed to it in a perpendicular way; a set of secondary blades perpendicularly joint to a sub-axis connected in angle to said vertical axis; a structure of lower blades; a discharge element comprising an opening and closing valve connected to a tray; and an air inlet located in one of the faces of the external tank.

A fluidized gas reactor includes a system for preventing a fluidizing gas comprising a reactant from premature reaction. The fluidized gas reactor includes a reaction chamber including a particle bed; a gas distribution plate having a plurality of openings therethrough, wherein each opening opens into the reaction chamber; and a plurality of vertical fluidizing gas inlet tubes, each of the fluidizing gas inlet tubes being in fluid communication with one of the openings in the gas distribution plate. Each fluidizing gas inlet tube is configured to receive a fluidizing gas and transport the fluidizing gas to the reaction chamber. A fluidizing gas source provides a stream of the fluidizing gas to the fluidizing gas inlet tubes. A coolant system prevents the fluidizing gas from undergoing reaction before entering the reaction chamber. The coolant system has a fluid inlet; a coolant flow path in fluid communication with the fluid inlet, the coolant flow path being configured to cool each fluidizing gas inlet tube; and a fluid outlet in fluid communication with the coolant flow path. Each fluidizing gas inlet tube may include a particle outlet and a valve system, where the valve system allows the fluidizing gas flow to the fluidizing gas inlet tubes to be stopped; and allows recovery of particles from the particle bed while the fluidizing gas flow is stopped.
