The invention discloses an anode with high activity, carbon deposition resistance and sulfur poisoning resistance for a solid oxide fuel cell. The anode is formed by compounding a metal material and a cerium-zirconium based oxide material. The anode disclosed by the invention can be used for effectively reducing the anode carbon deposition and the poisoning effect of a sulfur-containing compound on the anode for the solid oxide fuel cell which takes organic hydrocarbon as fuel, thereby reducing the polarization resistance of the anode and effectively enhancing the medium-low temperature property of a cell and the long-term stability of the cell.

The invention relates to the technical field of chemical tail gas treatment, and discloses a catalyst and a catalytic oxidation deoxidation method for unsaturated hydrocarbon-containing gas by using the catalyst. The catalyst contains a carrier, and an active component, a first auxiliary agent component and a second auxiliary agent component which are loaded on the carrier, wherein the active component is selected from one or more of oxides of Pt, Pd, Ru, Rh, Ag and Ir; the first auxiliary agent component contains one or more of rare earth metal elements, IVB group metal elements and VIII group metal elements, and the second auxiliary agent component contains one or more of alkali metal elements and alkaline earth metal elements. According to the deoxidation method using the catalyst, reducing gas such as H2 does not need to be added, hydrocarbon and oxygen directly react to generate CO2 and H2O, the purpose of deoxidizing hydrocarbon-containing tail gas is achieved, and carbon deposition can be prevented.

A fastening unit for fastening ignition units as part of a device for carbon deposition is provided, the fastening unit of the device having a first and a second holder, the ignition unit being situated between the two holders, and the holders being held together by at least one fastening device. The first holder has a first plane that has a first angle between 0° and 45° in relation to the longitudinal axis of the first holder. The ignition unit is situated such that the end surface of the ignition unit forms a right angle to the first plane.

The invention relates to a purification device suitable for high-boiling-point chemical raw materials, which comprises a purification tower and a hot-blast stove. The purification device, by fully utilizing the waste heat of the hot-blast stove, enables a combustion system, a waste heat boiler and a tower body to be naturally integrated. Overall distribution and centralized management of in-plantenergy are realized; therefore, the extracted fraction has higher purifty, and the height of the tower body is smaller. The temperature of a flue gas outlet can be controlled below 140 DEG C, adverseprocess conditions such as coking, carbon deposition, sublimation, atomization or easy formation of foam are avoided, and deep processing processes of rectification and distillation are innovated. Meanwhile, a cooling device is arranged outside the purification tower, so that the tower height is reduced, the cooling efficiency of the tower is improved, the fraction temperature before tower discharge is reduced and the heat efficiency of the tower is improved.

A modern multi-pole spark plug for use in an internal combustion engine and a method of using the same, include a device body, a switching device arranged in the device main body and a steering devicearranged in the device main body, The switching device comprises a steering cavity arranged in the main body of the device, a lifting groove with an opening upward and an annular array arranged on the lower inner wall of the steering cavity, a groove to be used with the opening downward communicating with the lower inner wall of the lifting groove, and a rotatable convex rotating block arranged in the steering cavity. The device can conveniently and quickly carry out electrode conversion on spark plugs used in internal combustion engines to prevent excessive carbon deposition between each other from affecting the use of the internal combustion engines, and the multi-pole switching spark plugs can also prolong the service life of the spark plugs and reduce the one-time use rate of energy consumables to achieve certain energy-saving effects.
