An object of the present invention is to provide an apparatus for continuous high temperature gas treatment of particulate matter, which can perform uniform high temperature gas treatment of particulate matter; and a method for treating particulate matter using the continuous high temperature gas treatment of particulate matter. The apparatus comprises a starting material supply port 1 through which starting particulate matter is supplied from an upper part of the apparatus; a treating gas supply port 2 through which a treating gas is supplied; a product discharge port 3 through which a product after treatment is discharged from a lower part of the apparatus; a treatment chamber 4 in which the particulate matter is treated with the treating gas; a gas-solid separation chamber 5 provided in fluid communication with an upper part of the treatment chamber 4; and a cooling chamber 6 provided in fluid communication with a lower part of the treatment chamber 4. A heating means 7 is provided on the outer periphery of the upper part of the treatment chamber 4, and a cooling means 8 is provided on the outer periphery of the cooling chamber 6. During operation of the apparatus, a moving bed 4a is formed in the lower part of the treatment chamber 4, and a fluidized bed 4b is formed to be continuous with an upper part of the moving bed 4a.
