Abstract: A method of recovering catalyst material from latent catalyst material solids includes: a) combining latent catalyst material solids with a liquid acid anolyte solution and a redox material which is soluble in the acid anolyte solution to form a mixture; b) electrochemically oxidizing the redox material within the mixture into a dissolved oxidant, the oxidant having a potential for oxidation which is effectively higher than that of the latent catalyst material; c) reacting the oxidant with the latent catalyst material to oxidize the latent catalyst material into at least one oxidized catalyst species which is soluble within the mixture and to reduce the oxidant back into dissolved redox material; and d) recovering catalyst material from the oxidized catalyst species of the mixture. The invention is expected to be particularly useful in recovering spent catalyst material from petroleum hydroprocessing reaction waste products having adhered sulfides, carbon, hydrocarbons, and undesired metals, and as well as in other industrial applications.

Abstract: The present invention provides methods of conducting chemical reactions in a reaction channel that has an varying cross-sectional area such that a chemical reactant or reactants experience varying local contact time as the reactant(s) flow through the channel. The invention also provides reactors having reaction channels with varying cross-sectional areas. In a particularly preferred embodiment, the reaction channel section has a trapezoidal shape that becomes broader from the inlet toward the outlet.
