Production of partially calcined carbonaceous reductant using steam

摘要

A process for producing chlorides by the chlorination of a material selected from the group consisting of aluminous materials and metal and metalloid oxides in the presence of a reductant. The method comprises calcining a carbonaceous material with added steam to oxidize substantially all precursors of chlorinated hydrocarbons and to form a reductant; and chlorinating a material selected from the group consisting of aluminous materials and metal oxides in the presence of the reductant.
