    摘要: In a process for oxidizing a hydrocarbon to a corresponding hydroperoxide, alcohol, ketone, carboxylic acid or dicarboxylic acid, the hydrocarbon is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide of the general formula (I): wherein each of R1 and R2 is independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SO3H, NH2, OH and NO2, or from the atoms H, F, Cl, Br and I provided that R1 and R2 can be linked to one another via a covalent bond; each of Q1 and Q2 is independently selected from C, CH, N and CR3; each of X and Z is independently selected from C, S, CH2, N, P and elements of Group 4 of the Periodic Table; Y is O or OH; k is 0, 1, or 2; l is 0, 1, or 2; m is 1 to 3, and R3 can be any of the entities listed for R1. The contacting produces an effluent comprising an oxidized hydrocarbon product and unreacted imide catalyst of said formula (I) and the effluent is treated with at least one solid sorbent chosen from alkali metal carbonates, alkali metal bicarbonates, alkali metal hydroxides, alkali metal hydroxide-carbonate complexes, alkaline earth metal carbonates, alkaline earth metal bicarbonates, alkaline earth metal hydroxides and alkaline earth metal hydroxide-carbonate complexes to remove at least part of the unreacted imide catalyst and produce a treated effluent comprising said oxidized hydrocarbon product. The organic phase can then be recovered.

    摘要: The electrodesulfurization of heavy oil feedstreams is accomplished wherein a heavy oil feedstreams, along with hydrogen, is passed the cathode side of an electrochemical cell wherein the organically bound sulfur compounds in the heavy oil are reduced and the sulfur is released as hydrogen sulfide. The hydrogen sulfide can be fed directly into the anode side of the electrochemical cell to produce sulfur and hydrogen or it can be passed to an oxidation zone containing an aqueous solution of an oxidized metal salt.

    摘要: A digital controller for dc-dc switching converters can operate under light load conditions. The controller can be suitable for the use in switch-mode power supplies providing regulated output voltage for handheld devices and other low-power electronics. To create long time intervals, compared to the propagation time of digital logic a DPFM/DPAM can use a ring oscillator with two sets of delay cells and two signals racing around the ring.
