  • DIATOMACEOUS ENERGY STORAGE DEVICES
    Publication number: 20240347738
    Abstract: The disclosed technology generally relates to energy storage devices, and more particularly to energy storage devices comprising frustules. According to an aspect, a supercapacitor comprises a pair of electrodes and an electrolyte, wherein at least one of the electrodes comprises a plurality of frustules having formed thereon a surface active material. The surface active material can include nanostructures. The surface active material can include one or more of a zinc oxide, a manganese oxide and a carbon nanotube.

  • Process for recovery of sulfur values from a gas stream
    Patent number: 5057298
    Abstract: The invention is a process wherein SO.sub.2 is absorbed in a concentrated solution of potassium citrate and the solution is reacted with H.sub.2 S at a temperature above the melting point of sulfur to form elemental sulfur. The reaction produces a solution lean in sulfur dioxide. SO.sub.2, in the form of a rich solution or a gas, can be introduced into the lean solution in order to inhibit post-formation of sulfur. This introduction of SO.sub.2 avoids a tendency for sulfur to form continually after the solution exits the reaction zone.

  • Plasma arc process for the reduction of sulfur dioxide to sulfur
    Patent number: 4367211
    Abstract: A continuous process for the reduction of sulfur dioxide to sulfur in which a gas stream containing sulfur dioxide is contacted with a carbon source in the form of particulate coal at a temperature of at least 600.degree. C. in a plasma arc reaction zone generated by a rotating direct current arc.
