A first electrode arrangement and a transport element are movable relative to a support. A working space is disposed between the movable elements for advancing moist material along a processing path. As the moist material advances, electrical current is passed through the material between the first electrode arrangement and a second electrode arrangement adjacent the transport element. An acoustic transducer arrangement disposed adjacent the working space simultaneously subjects the moist material to an acoustic field as the material moves along the processing path. The acoustic field is generated by an array of acoustic transducers spaced along part of the processing path.

Apparatus and method for removal of liquids

Apparatus and method for the in-situ removal of soil contaminants by the concurrent application of a D.C. electrical field and an acoustic field.

Electroacoustic soil decontamination

Methods and apparatus for reacting materials to provide a product. In a reactor (20) having an inner column (A) and an adjacent coaxial outer column (B), and having an upper zone (II) and an adjacent lower zone (I), both zones (I,II) are filled with a liquid (C). A gas (4) is fed into the liquid (C) at the lower end of the upper zone (II). The liquid (C) and a part of the gas (4) are circulated generally upward in one column (A or B) and generally downward in the other column (B or A) in the upper zone (II). Particles (15) of a solid substance are provided in a column (A or B) in the lower zone (I). The liquid (C) is circulated between the lower zone (I) and the upper zone (II) in such manner that the liquid (C) contacts and fluidizes the solid particles (15) while confining them to the lower zone (I), while the gas (4) contacts the liquid (C) and is confined to the upper zone (II).

Reacting materials

A method of reducing the amount of gaseous sulfur compounds released during combustion of sulfur-containing fuel, comprising the steps of: (a) preparing a mixture of sulfur containing particulate fuel and a sulfur absorbent, such as calcium oxide, calcium hydroxide, calcium carbonate, lime, limestone, dolomite, or mixtures thereof; (b) exposing the mixture to a reducing atmosphere at a temperature of at least about 1500.degree. F., so as to convert at least a portion of the particulate fuel into a gaseous portion and a solid, char portion; and (c) combusting the char portion, thereby forming an ash containing sulfur fixed therein.
