Highly selective zirconium oxychloride modified Pd/C catalyst in the hydrodechlorination of dichlorodifluoromethane to difluoromethane

J. Krishna Murthy; S. Chandra Shekar; V. Siva Kumar; K.S. Rama Rao

Zirconium oxychloride modified active carbon supported palladium catalyst appears to be a promising system in the hydrodechlorination of CCl2F2 to yield CH2F2 in greater yields; showing an altogether different product distribution compared to Pd/C and Pd/ZrO2 catalysts. The catalysts have been characterized by BET-surface area, CO-chemisorption, X-ray diffraction (XRD), temperature programmed reduction (TPR) analysis and fluorine contents in used catalysts. The interaction of Zr species with Pd and the formation of fluorinated zirconium species during the course of reaction led to the higher selectivity towards CH2F2.
