  • Patent number: 10233552
    Abstract: This invention is a method and apparatus for operating electrochemical reactors with multi-phase feeds, in which a liquid feed stream is dispersed in a second fluid to form a spray, mist or emulsion before entering the reaction zone. The invention is applicable to both electro-synthesis and fuel cell reactors, with particular utility in mixed-reactant fuel cells.

  • Publication number: 20160068974
    Abstract: In various embodiments, the invention provides electro-chemical processes for reduction of carbon dioxide, for example converting carbon dioxide to formate salts or formic acid. In selected embodiments, operation of a continuous reactor with a three dimensional cathode and a two-phase (gas/liquid) catholyte flow provides advantageous conditions for electro-reduction of carbon dioxide. In these embodiments, the continuous two-phase flow of catholyte solvent and carbon dioxide containing gas, in selected gas/liquid phase volume flow ratios, provides dynamic conditions that favour the electro-reduction of COs at relatively high effective superficial current densities and gas space velocities, with relatively low reactor (cell) voltages (<10 Volts). In some embodiments, relatively high internal gas hold-up in the cathode chamber (evident in an internal gas to liquid phase volume ratio >0.

  • Patent number: 8709680
    Abstract: A cell unit of a mixed reactant fuel cell comprises a multiphase mixed reactant fluid distributor, an anode and cathode in fluid and electronic communication with the distributor, and a separator positioned relative to one of the anode and the cathode to provide electronic insulation and ionic communication between the cell unit and another adjacent cell unit. The distributor is electronically conductive and the reactant fluid which flows through the distributor has fuel and oxidant each in separate fluid phases, wherein at least one of the fuel and oxidant fluid phases is a liquid.

  • Publication number: 20080060879
    Abstract: The invention provides, in general, a reusable gas driven fluid transportation apparatus having subsystems or components that are adapted to be reused, replaced and/or recycled. All or a portion of the subsystems or components of the apparatus may be reused by replacement of parts (such as the gas generating unit) or by replacement of consumed components such as gas generating reactants, batteries or fluid. The apparatus may be used, for example, for applying lubricant to machine components such as a bearing.

  • Publication number: 20070108045
    Abstract: The invention provides methods and devices for the electrochemical generation of nitrogen from organic nitrogen compounds, such as hydrazides (RCONHNH2), the corresponding organic hydrazino-carboxylates (RCO2NHNH2) and amino-guanidine salts (e.g. aminoguanide bicarbonate H2NNHC (NH) NH2H2CO3). A variety of organic hydrazides and hydrazino-carboxylates may be used, and empirically tested for performance. For example, in the hydrazides and hydrazino-carboxylates “R” may be an alkyl, alkenyl, alkynyl or aryl group, in some embodiments methyl, ethyl, or benzyl. The alkyl, alkenyl and alkynyl groups may be branched or unbranched, substituted or unsubstituted. The utility of such compounds may be routinely assayed in accordance with the guidance provided herein, including the Examples set out herein in which alternative nitrogen compounds may be substituted for routine test purposes.

  • Publication number: 20050011769
    Abstract: A cetylpyridinium salt, cetylpyridinium chloride (CPC) is used as a hydrogen evolution inhibitor (a current efficiency improver) in a commercial zinc electrowinning process. Zinc electrowinning compositions containing a) antimony and b) antimony and glue were tested. Adding CPC at a 0.05 mM concentration to the electrowinning liquor resulted in increased current efficiency for both electrolytes.
