text: Specifically, the highly active metal is placed in a section with a higher temperature (a first temperature, e.g., 500˜1500° C., preferably 700˜1,000° C.), and the titanium dioxide is placed in a section with a lower temperature (a second temperature, e.g., 100˜600° C., preferably 300˜500° C.), such that a dual-temperature-zone reduction system is realized by a simple device.
