Abstract:
An apparatus for mixing a fluid feedstock and particles of a catalyst for gasifying the fluid, which comprises a plurality of stand pipes extending vertically; a distributing device for distributing the particles uniformly into said stand pipes; a mixing section positioned below said distributing device from an interior of which said stand pipes extend to an upper interior of said mixing section to feed the particles thereto; a plurality of upper disk-, dish- or cone-shaped plates having diameters no less than those of lower ends of said stand pipes, said plates being arranged in a horizontal array in said mixing section and below said stand pipes for dispersing of the particles falling therefrom outwardly in a radial direction; and a fluid feed section arranged in said mixing section in surrounding relation to an outer periphery of each of the stand pipes to spray the fluid downwardly in a vertical direction in close proximity and in surrounding relation to an entire outer periphery of a column of particles falling from each of the stand pipes so as to collide with the particles after being dispersed by the plates.
