ABSTRACT:
Catalytic hydrogenolysis of fluorohalocarbons (e.g., CFCs) and fluorohalohydrocarbons (e.g., HCFCs), using catalysts of Re, Co, Ni, Ru, Rh, Pd, Os, Ir, and/or Pt on a carbon having low ash content. Preferred catalysts use carbon which is acid-washed, first with an acid other than hydrofluoric acid and then with hydrofluoric acid; and also have a low content of phosphorus, sulfur, potassium, sodium and iron.
