  • Process for producing aluminum trichloride
    Patent number: 3956454
    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.

  • Production of aluminum chloride from raw materials containing coal
    Patent number: 3950485
    Abstract: A process for the production of aluminum chloride from raw materials such as coal slate or bituminous shale is disclosed. The raw material should preferably have an ash content of at least 30% by weight, and with the aluminum content of the ash being at least 20%, calculated as Al.sub.2 O.sub.3. The raw material is first calcined and then chlorinated with a gaseous stream containing chlorine and carbon monoxide to form the aluminum chloride product.
