Abstract: A gas-solid separating method and a gas-solid separating system for simple substance sulphur in sulphur-containing exhaust are provided. The gas-solid separating method for simple substance sulphur in sulphur-containing exhaust comprises the following steps: first, cooling sulphur-containing exhaust at an extremely high speed; then, separating dust; finally, recycling a heavy liquid phase solvent and simple substance sulphur. The system comprises a quick cooling system, a low-temperature washing and purifying system, a light liquid phase and heavy liquid phase separating system, a washing liquid recycling system and a simple substance sulphur recycling system.

Abstract: The present invention discloses a preparation method of a catalyst with white carbon black modified by Zr—Nd—O and use thereof, and belongs to the field of catalyst technologies. In the present invention, an organic solvent evaporation induced self-assembly method is used to load Zr—Nd—O onto white carbon black to obtain a mesoporous Zr—Nd—O/white carbon black catalyst. The mesoporous Zr—Nd—O/white carbon black catalyst in the present invention has high catalytic activity, contains uniformly distributed mesopores with a relatively large average aperture, and has a simple preparation process, etc.
