Title: Method for recovering valuable elements from precombustion coal-based materials

Abstract

A method for recovering valuable elements from pre-combustion coal-based materials includes the steps of grinding the materials to a predetermined size, roasting the ground materials at a temperature of 600° C.-700° C. for a predetermined residence time needed for mineral decomposition, submerging the roasted, ground materials in a solution of lixiviant, filtering the lixiviant solution to separate residual solids from a pregnant leach solution including the valuable elements and recovering and concentrating the valuable elements from the pregnant leach solution.

Method for recovering catalytic elements from fuel cell membrane electrode assemblies

Patent Shore, Lawrence [Edison, NJ]; Matlin, Ramail [Berkeley Heights, NJ]; Heinz, Robert [Ludwigshafen, DE]

A method for recovering catalytic elements from a fuel cell membrane electrode assembly is provided. The method includes converting the membrane electrode assembly into a particulate material, wetting the particulate material, forming a slurry comprising the wetted particulate material and an acid leachate adapted to dissolve at least one of the catalytic elements into a soluble catalytic element salt, separating the slurry into a depleted particulate material and a supernatant containing the catalytic element salt, and washing the depleted particulate material to remove any catalytic element salt retained within pores in the depleted particulate material.

Method of removing and recovering elemental sulfur from highly reducing gas streams containing sulfur gases

Patent Gangwal, Santosh K.; Nikolopoulos, Apostolos A.; Dorchak, Thomas P.; ...

A method is provided for removal of sulfur gases and recovery of elemental sulfur from sulfur gas containing supply streams, such as syngas or coal gas, by contacting the supply stream with a catalyst, that is either an activated carbon or an oxide based catalyst, and an oxidant, such as sulfur dioxide, in a reaction medium such as molten sulfur, to convert the sulfur gases in the supply stream to elemental sulfur, and recovering the elemental sulfur by separation from the reaction medium.

Method for removing sulfur oxide from waste gases and recovering elemental sulfur

Patent Moore, Raymond H [Richland, WA]

A continuous catalytic fused salt extraction process is described for removing sulfur oxides from gaseous streams. The gaseous stream is contacted with a molten potassium sulfate salt mixture having a dissolved catalyst to oxidize sulfur dioxide to sulfur trioxide and molten potassium normal sulfate to solvate the sulfur trioxide to remove the sulfur trioxide from the gaseous stream. A portion of the sulfur trioxide loaded salt mixture is then dissociated to produce sulfur trioxide gas and thereby regenerate potassium normal sulfate. The evolved sulfur trioxide is reacted with hydrogen sulfide as in a Claus reactor to produce elemental sulfur. Themore » « less

Method for recovering light hydrocarbons from coal agglomerates

Patent Huettenhain, Horst [Benicia, CA]; Benz, August D [Hillsborough, CA]; Getsoian, John [Ann Arbor, MI]

A method and apparatus for removing light hydrocarbons, such as heptane, from coal agglomerates includes an enclosed chamber having a substantially horizontal perforate surface therein. The coal agglomerates are introduced into a water bath within the chamber. The agglomerates are advanced over the surface while steam is substantially continuously introduced through the surface into the water bath. Steam heats the water and causes volatilization of the light hydrocarbons, which may be collected from the overhead of the chamber. The resulting agglomerates may be collected at the opposite end from the surface and subjected to final draining processes prior to transportationmore » or use. « less
