A catalyst for catalytic oxidation-deoxidation method of unsaturated hydrocarbon-containing gas has a carrier, an active component, a first co-agent component, and a second co-agent component loaded on the carrier respectively. The active component is one or more selected from the group consisting of oxides of Pt, Pd, Ru, Rh, Ag and Ir. The first co-agent component has one or more selected from the group consisting of a rare earth metal element, a group IVB metal element and a group VIII metal element; and the second co-agent component has one or more alkali metal element and alkaline earth metal element. The deoxidation method using the catalyst eliminates the need to add a reducing gas such as H, allows hydrocarbons to react directly with oxygen to produce COand HO, achieves the goal of deoxidating a hydrocarbon-containing tail gas, and can prevent the generation of carbon deposits.

Described are a low temperature plasma reaction device and a hydrogen sulfide decomposition method. The reaction device includes: a first cavity; a second cavity, the second cavity being embedded inside or outside the first cavity; an inner electrode, the inner electrode being arranged in the first cavity; an outer electrode; and a barrier dielectric arranged between the outer electrode and the inner electrode. The hydrogen sulfide decomposition method includes: implementing dielectric barrier discharge at the outer electrode and the inner electrode of the low temperature plasma reaction device, introducing a raw material gas containing hydrogen sulfide into the first cavity to implement a hydrogen sulfide decomposition method, and continuously introducing a thermally conductive medium into the second cavity in order to control the temperature of the first cavity of the low temperature plasma reaction device.

The present disclosure relates to a downhole rotating magnetic field generator, wherein a stator assembly is formed by fixedly connecting a guiding stator, windings, and a body together, and a rotor assembly is formed by mounting a turbine rotor and a permanent magnet together. Between the stator assembly and the rotor assembly, sliding bearings are arranged and small mud passages are formed. There is no metal isolation between the rotor and the stator for cutting through the magnetic lines of force, so that the eddy current loss is relatively small. Meanwhile, with mud flowing through the passages as lubricant, overheating of the generator can be prevented and high power output can be ensured.
