| 181 | Method and apparatus for generating high temperature zone using fixed-fluidized bed | US33640873 | 1973-02-28 | US3892538A | 1975-07-01 | SETH RAM GOPAL |
| Method and apparatus for generating high temperatures within a controlled zone by utilizing a fixed-fluidized bed which employs larger fixed particles incapable of fluidization disposed in the lower region of a bed of smaller particles capable of fluidization. A combustible gas mixture is burned within the bed and passed through the bed at a superficial velocity at or slightly below the minimum fluidization velocity of the smaller fluidized particles. The larger fixed particles stabilize the fluidization of the bed and permit the combustion of the gases to be localized within a small high temperature zone at the top of the fluidized bed.

| A fluidized bed system for pyrolysis or incineration of solid wastes is provided. The solids feed is force fed to a fluidized bed apparatus having a conically shaped distributor plate and a first internal chamber above the distributor plate and a smaller second internal chamber connected to the first chamber and positioned directly below the first chamber. Solid waste is fed into the apparatus by a feeder which seals the feeder from the apparatus at a point spaced from hot-zone of the apparatus. The system has fluidizing gas inlets which are designed so that fluidized bed in the first internal chamber is more highly fluidized than the fluidized bed in the second internal chamber. A lock in the second internal chamber permits removal of nonreacted materials without interruption in operation of the system.

| The present invention concerns 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 (1) made in a first roasting reactor (16) and a second roasting step (3) made in a second roasting reactor (17). A gas mixture is formed from the first process gas component (2) obtained from the first roasting step(1)and from the second process gas component (4) obtained from the second roasting step (3). Post combustion of the gas mixture is made in a post combustion chamber (6). The post combustion operates with said reducing and sulphide rich first process gas component (2) and the second process gas component (4) as oxidizer gas in order to decompose SO3 in the gas mixture to reduce the SO3 content. The risk of accretion formation and corrosion in the post combustion chamber and in subsequent steps is reduced. Finally the exit gas (7) is exposed to sub sequent gas cooling and dust removal steps (8 to 11). | ||||||

| An apparatus and process is disclosed for the treatment of a component using a fluidised bed of powder. The apparatus includes a treatment chamber for receiving at least a treatment part of the component and a powder reservoir. The powder reservoir has heating or cooling means for controlling the temperature of the powder.

| 199 | Apparatus and process for regenerating catalyst | US10246100 | 2002-09-17 | US07026262B1 | 2006-04-11 | Paolo Palmas; David A. Lomas |
| Disclosed is an apparatus and process for prolonging the residence time of catalyst in a chamber for regenerating catalyst. Spent catalyst, perhaps from an FCC reactor, is introduced into a chamber of a regeneration vessel between lower and higher combustion gas distributors. The velocity of gas from the lower distributor is insufficient to entrain catalyst from the bed, and gas from the higher distributor when combined with gas rising from the lower distributor is sufficient to generate a fast fluidized flow condition. The second distributor elevates the location of the transition from turbulent bed to fast fluidized conditions. | ||||||
