    摘要： Trace element levels of heavy metals in crude oil are reduced by contacting the crude oil with an oxidizing agent, extracting heavy metals into a water phase for subsequent separation from the crude oil. The oxidizing agent is selected from the group of hydroperoxides, organic peroxides, inorganic peracids and salts thereof, organic peracids and salts thereof, and ozone. In one embodiment, the oxidizing agent converts heavy metals into the heavy metal cations in a water-oil emulsion, which can be subsequently separated from the crude oil, for a treated crude oil having reduced levels of heavy metals. In one embodiment, at least a complexing agent can be added to facilitate the removal by forming soluble heavy metal complexes in the water phase.

    摘要： Alkali metals and sulfur may be recovered from alkali polysulfides in an electrolytic process that utilizes an electrolytic cell having an alkali ion conductive membrane. An anolyte solution includes an alkali polysulfide and a solvent that dissolves elemental sulfur. A catholyte solution includes alkali metal ions and a catholyte solvent. Applying an electric current oxidizes sulfur in the anolyte compartment, causes alkali metal ions to pass through the alkali ion conductive membrane to the catholyte compartment, and reduces the alkali metal ions in the catholyte compartment. Sulfur is recovered by removing and cooling a portion of the anolyte solution to precipitate solid phase sulfur. Operating the cell at low temperature causes elemental alkali metal to plate onto the cathode. The cathode may be removed to recover the alkali metal in batch mode or configured as a flexible band to continuously loop outside the catholyte compartment to remove the alkali metal.

    摘要： A method of and system for reducing engine environmental atmospheric pollution emissions from a vehicle having a combustion engine utilizing hydrocarbon fuel for at least one of propulsion and auxiliary electrical power is disclosed. The method basically includes providing an unprocessed bulk fuel storage container and a clean processed fuel tank on the vehicle, supplying the engine for propulsion with fuel from the unprocessed fuel storage container when the vehicle is beyond a predetermined distance from an area having environmental restrictions passing a portion of unprocessed fuel through a desulphurization process to fill a clean fuel storage container while the vehicle is in motion and supplying the combustion engine for one of propulsion and auxiliary electrical power from clean fuel in the processed fuel storage container when the vehicle is within an area having environmental restrictions.
