    Abstract: Chlorine dioxide is generated from an aqueous solution of sodium chlorite in the presence of a catalyst having a reduced rate of deactivation. The catalyst is preferably palladium, or palladium together with another platinum group metal (e.g., Pd+Pt), or palladium together with a Group IB metal (e.g., Pd+Au) deposited on a support modified by Group IA carbonate salt (e.g., K2CO3) or a Group IIA carbonate salt (e.g., CaCO3) or a magnesium salt that can be converted to MgO or a support consisting of a Group IA carbonate salt or a Group IIA carbonate salt or a magnesium salt that can be converted to MgO.

    Abstract: The catalytic mixture resulting of a metal powder catalyst with a solid material (referred to here as a reaction-aid) that has good filtering properties, does not interfere with the reaction, does not interfere with recycling the catalyst back into the reaction, does not interfere with the refining and recovery of the metal from the catalyst after it is spent, and will not become separated from the catalyst during the preparation of this catalytic mixture, the chemical reaction or the separation of this catalytic mixture from the reaction medium, whereas the ratio of the reaction aid to the catalyst ranges from 0.05 to 20 on a weight basis. A preferred metal powder catalyst is acetylene black supported precious metal. Preferred reaction aids are sibunit powder or activated carbon. The catalytic mixture can be used for the catalytic transformation of compounds, such as the hydrogenation of olefins, or the hydrogenation of nitro compounds.

    Abstract: Nitro-compounds are hydrogenated with an activated Ni catalyst whose Ni/Al alloy also contained one or more elements from the list of Cu, Ag and Au prior to activation. In combination with the Group IB elements mentioned above, this catalyst can also be doped with other elements via their addition to the Ni/Al alloy prior to activation and/or they can be adsorbed onto the surface of the catalyst either during or after the activation of the alloy. The suitable doping elements for the alloy prior to activation in combination with the group IB elements mentioned above are one or more of the elements from the list of Mg, Ti, Ce, Cr, V, Mo, W, Mn, Re, Fe, Co, Tr, Ru, Rh, Pd, Pt and Bi. The suitable doping elements that may be adsorbed onto the surface of the catalyst that was previously doped in the alloy prior to activation with the group IB elements mentioned above are one or more elements from the list Mg, Ca, Ba, Ti, Ce, V, Cr, Mo, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Pd, Pt, Ni, Cu, Ag, Au and Bi.
