  • Patent number: 9487876
    Abstract: The electrolysis of cuprous chloride was carried out in the electrochemical cell. The particle size, current density, cathodic current efficiency, conversion of cuprous chloride and yield of copper formed depends strongly on current flow, heat transfer and mass transfer operation. The current flow, heat transfer and mass transfer are depends on surface area ratio of anode to cathode, distance between electrodes, concentration of HCl, applied voltage, flow rate of electrolyte, CuCl concentration and reaction temperature. The electrolysis of cuprous chloride as a part of Cu—Cl thermochemical cycle for hydrogen production is experimentally demonstrated in proof-of-concept work.

  • Patent number: 9447512
    Abstract: The electrochemical cell consists of hollow tube and centralized copper rod. The tubes have first and second ends. The first end cap is used to close the first open end. The anolyte inlet is extended through the first end cap in anolyte compartment and catholyte inlet is extended through the first end cap in catholyte compartment. The anolyte and catholyte compartments are separated by ion exchange membrane fixed over inner hollow tube having holes on the surface. A first Teflon gasket has provision for inlet of anolyte and catholyte tube is secured between first tubes end and first end cap. The copper rod is placed at the center of the tubes acts as cathode. The circular ring works as scrapper to take out deposited copper is provided. A second end cap is used to close the second open. A second Teflon gasket is secured between second tubes end and second end cap.

  • Patent number: 6177596
    Abstract: An active highly acidic microporous solid catalyst comprising sulphated metal oxide and at least one of carbon molecular sieve and/or heteropoly acid and having pore volume in the range of 0.1-0.2 m3/g and pore size distribution in the range of 25-40 Å for use in acid catalized organic reactions which occur in the microporous range of the catalysts such as nitration of aromatic compounds, cyclization of terpenoids and more particularly relates to the preparation of modified sulphated zirconia catalysts. The invention also covers the process for producing the abovesaid solid catalyst and its use in producing isopulegol-rich in 1-isopulegol isomer from d-citronellal and in process for mononitration of aromatic compounds C6H4R1R2 wherein R1=—CH3, —C2H5, —Cl, —Br or —I and R2—H or —CH3.
