Mechanism of fluidized chlorination reaction of Kenya natural rutile ore
From 900 to 1,000 °C, the apparent activation energy is 10.569 kJ·mol −1. In this temperature range, mass diffusion is the main reaction controlling step. The empirical equation for the rate of Kenya rutile chlorination in the C–Cl 2 system is obtained, and fits with the experimental data fairly well.
