[0002] Pyrolysis technology refers to the thermochemical conversion technology of organic solid waste, which decomposes organic macromolecules through thermochemical reactions under oxygen-deficient / oxygen-limited conditions and converts them into organic fuels or chemical raw materials. High-titanium slag is the common name for titanium ore enrichment formed through a physical production process. The titanium ore is melted by heating in an electric furnace, and the titanium dioxide and iron in the titanium ore are melted and separated to obtain a high-content titanium dioxide enrichment.
