The relatively small degree of backmixing of gas in a well-arranged fast fluidized bed is exploited to introduce heat into a fluidized bed reaction system wherein a fluidized bed treatment zone receiving heat and for the purpose of conducting an endothermic treatment of matter can have a gas atmosphere, such as relatively pure steam, that is maintained independently of and without admixture by any gas or gases that are associated with a step for introducing the heat. The treatment advantageously constitutes a treatment of a carbonaceous matter, such as coal or petroleum or municipal solid waste, with hot steam for purpose of gasifying or carbonizing or cracking the matter. The arrangement is also useful for a broad range of endothermic chemical or physical treatment of matter at high temperature. Heat is introduced into an upper fast fluidized bed zone and flows by conduction downward into a lower fluidized bed zone, that may comprise a treatment zone, or sometimes the heat flows onward by conduction to other fluidized bed treatment zones not in communication with the upper zone, to permit withdrawal of gaseous products of the treatment substantially without dilution by a gas associated with the step of supplying heat to the upper zone.

A process for gasifying carbonaceous matter by treatment with hot steam to yield a fuel gas containing hydrogen, carbon monoxide, and methane, comprising: (a) fluidizing granular carbonaceous material in a first fluidized bed extending continuously from substantially the bottom to substantially the top of a first space, and wherein said bed is maintained at a temperature between about 1,400°and 1,900°F.; (b) supplying carbonacious matter to said bed, and wherein said matter is selected from the group consisting of coals, cokes, lignites, asphalt, coal tar, heavy coker tars, bitumens, petroleum resudua, Gilsonite, and kerogen, and wherein said granular carbonaceous material originates from said carbonaceous matter and includes fine particulate material; (c) supplying a gas comprising primarily steam as fluidizing gas to the bottom of said first bed and thereby converting at least a part of said carbonaceous matter by its endothermic reaction with steam to a fuel gas containing hydrogen, carbon monoxIde, and methane; (d) fluidizing granular carbonaceous material also originating from said carbonaceous matter in a second fluidizing bed extending continuously from substantially the bottom to the top of a second space, and wherein said second space is annular in shape and is concentrically disposed within and alongside the upper portion of first space, the top of said second space being open to said first space at a selected elevation between top and bottom of said first space, so that said second fluidized bed is contiguous with said first bed at said selected elevation and gas leaving said second bed acts as a part of the fluidizing gas to the region of said first bed above said selected elevation, and wherein the combined rate of flow of said gas leaving said second bed and of fluidizing gas in said first bed reaching said selected elevation from below is sufficient to maintain a fast fluidized condition of said fine particulate material in said region of said first bed; (e) supplying a gas containing oxygen as fluidizing gas to said second bed, thereby sustaining combustion of said granular carbonaceous material in said second bed and generating heat that passes by conduction into said first bed; (f) withdrawing gas together with said fine particulate material from substantially the top of said first space and said second space; (g) substantially separating said withdrawn gas from said withdrawn fine particulate material; (h) discharging said gas; (i) feeding said separated fine particulate material into a third fluidized bed wherein said fine particulate material is maintained in the slow fluidized condition; and (j) feeding said separated fine particulate material from said third fluidized bed into said first fluidized bed at a rate sufficient to maintain a fast fluidized zone in said region of said first bed above said selected elevation. Apparatus for conducting endothermic reactions of carbonaceous matter in a treatment by contact with hot steam, comprising: (a) a vessel; (b) a vertical annular partition means connected at its upper and thereof to the interior wall of said vessel and forming a central first space and an annular second space within said vessel, said first space extending from the bottom of said partition to the top of said vessel, and wherein the bottoms of said spaces are open to a third space within said vessel and subposed beneath said first and second spaces, and a fourth space subposed beneath and in communication with said third space; (c) means connected to said first space and said fourth space for feeding a carbonaceous matter into said vessel; (d) means for establishing in said first space a hot fluidized bed of particulate matter including fine particles and originating from said carbonaceous matter; (e) means for establishing hot fluidized beds in said second and third spaces of particulate matter originating from said carbonaceous matter, and wherein said means for establishing hot fluidized beds in said first, second, and third spaces include means for introducing gas comprising primarily steam as a fluidizing gas to substantially the bottom of said third space; (f) means for introducing a hot gas into said first space at a selected elevation of said first space, and wherein said means for introducing a gas comprising primarily steam and said means for introducing a hot gas are capable of sustaining rates of said introductions such as to maintain a rate of flow of fluidizing gas in the region of said first space above said selected elevation sufficient to establish a fast fluidized bed of said fine particles in said region; (g) means for withdrawing and separating gas and fine particles from the top of said second space; (h) means for withdrawing and separating gas and fine particles from the top of said first space; (i) pipe means for each of said separating means for discharging said separated gas; and (j) means for conducting said separated particles from said separating means (g) and (h) into said third space at a rate of flow sufficient to establish a fast fluidized bed zone of said paricles in said third space.
