摘要 |
The present invention relates to a method for treating fluoro-containing and silicon-containing gas. The method comprises treating the gas with thermal-treating, particles-treating, catalyst-treating, and acid-removing sequentially to remove perfluorocompounds. The invention achieves results of reducing the working temperature, increasing the lifetime of the catalyst, reducing the operating cost of the system, and increasing the applications of the catalyst in the aspect of fluoride-containing gas, silicon-containing gas and particles containing gas treatment by sequential treating.
