Abstract
The instant invention is particularly useful for using low-grade carbonaceous material to form aluminum-trichloride. Aluminous material and the carbonaceous material are comminuted either separately or together, and then the aluminous and carbonaceous materials are either compacted or mixed with a binder to form a doughlike paste. The compacting or mixing with the binder to form the dough-like paste is to insure that the particulate aluminous and carbonaceous materials have extremely close and intimate contact. The mixture is then calcined and chlorinated at an elevated temperature to form aluminum trichloride.
