摘要： A process and apparatus of preventing the plugging of the discharge and/or suction line of an internal recycle pump utilized in an expanded bed reactor of the type having a partition transversely extending through the lower portion thereof and defining a plurality of substantially regularly and uniformly disposed perforations and communicating with a reaction zone above the partition and plenum chamber therebelow. The reaction zone contains a mass of particulate catalyst contact matter supported by the partition and placed in randon motion above the partition by a pressurized mixture of a liquid carbon containing material and a hydrogen rich gas flow passing through the perforations from the plenum chamber and by the internal recycle pump having a pump suction line generally concentrically disposed with respect to the reactor and extending through the partition into the reaction zone. The pump has a discharge communicating with the plenum chamber and is situated in the bottom of the reactor and has an exterior surface which extends into the atmosphere. The pump functionally recycles the liquid carbon containing material from the reaction zone through the recycle pump discharge into the plenum chamber and through the perforations in the partition. The improvement comprises extending a first catalyst withdrawal line from the pump suction line into the atmosphere to withdraw catalyst matter and prevent plugging with particulate catalyst contact matter of the recycle pump discharge and/or the suction line.

摘要： A counter-current catalyst regenerator with at least two stages of counter-current contact along with a regenerator riser is proposed. Each stage may comprise a permeable barrier that allows upward passage of oxygen-containing gas and downward passage of coked catalyst into each stage, but inhibits upward movement of catalyst to mitigate back mixing and approximate true counter-current contact and efficient combustion of coke from catalyst. The regenerator riser may provide a passage to transport the catalyst and may serve as a secondary stage for coke combustion to provide the regenerated catalyst.

摘要： A process and a plant for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur containing components. The process comprises a two-stage roasting process comprising a first roasting step and a second roasting step. A gas mixture is formed from the first process gas component obtained from the first roasting step and from the second process gas component obtained from the second roasting step. Post combustion of the gas mixture is made in a post combustion chamber that uses the sulphide rich first process gas component and the second process gas component as oxidizer gas in order to decompose SO3 in the gas mixture. The exit gas is exposed to subsequent gas cooling and dust removal steps.

摘要： The auger gasifier described includes, in its preferred embodiments, a vertically elongated (“oblong”) primary gasifier chamber with an auger that can move up and down, allowing for large amounts of fuel input when necessary. This improvement, in turn, requires and/or is facilitated by provision for simultaneous elevation adjustments of the auger and bed dam to assure that fuel material is processed in degrees from the top downward without sweeping massive amounts of the fluidized bed materials towards the output end of the chamber. Another improvement involves provision for pressurization of the primary gasifier chamber, allowing substantial improvements in the speed of processing materials through the gasifier. Due to issues arising from thermal expansion of the refractory material lining the chamber, provision is made for nozzle and refractory imbedded pipe hole thermal expansion capability. Finally, provision is for steam injection into and/or auxiliary heating of the chamber to enhance gasification and the production of syngas.
