Title (EN) CATALYTIC HYDROGENOLYSIS
(FR) HYDROGENOLYSE CATALYTIQUE
Abstract: front page image
(EN)Catalytic hydrogenolysis of fluorohalocarbons (e.g., CFCs) and fluorohalohydrocarbons (e.g., HCFCs), using low-phosphorous, low-sulfur catalysts of Re, Co, Ni, Ru, Rh, Pd, Os, Ir, and/or Pt on carbon. Preferred catalysts are acid-washed and also have a low content of potassium, sodium and iron.
(FR)L'invention se rapporte à l'hydrogénolyse catalytique de fluorohalocarbone (notamment les CFC) et de fluorohalohydrocarbones (notamment les HCFC), qu'on obtient en utilisant des catalyseurs, à faible teneur en phosphore et en soufre, de Re, Co, Ni, Ru, Rh, Pd, Os, Ir et/ou Pt sur du carbone. Les catalyseurs préférés sont lavés à l'acide et ont également une faible teneur en potassium, sodium et fer.
