AI Technical Summary
The existing carbochlorination processes face challenges due to the unsuitability of low-density carbonaceous materials like biochar and green coke for titanium dioxide production, leading to increased demand and cost for petroleum coke, which is not economically viable.
A feedstock composite comprising a metal oxide fraction and a carbonaceous fraction with controlled densities, using binders like lignosulfonate, carboxymethyl cellulose, and water glass, to create a composite suitable for carbochlorination processes, including biochar and pyrolytic coke, with densities between 0.8-1.15 g/cm³ and particle sizes of 0.1-6.0 mm.
Enables the use of alternative carbonaceous materials, reducing the reliance on petroleum coke and lowering production costs by utilizing low-cost, environmentally friendly alternatives like biochar and pyrolytic coke in titanium dioxide production.
