Hydrodehalogenation Reaction on Carbon-Supported Palladium Catalyst

摘要

In this study, dichlorodifluoromethane was hydrodehalogenated on Pd/carbon catalyst. Activated carbon and activated carbon fiber were used as a catalyst support. The main products were difluoromethane, methane, chlorofluoromethane, hydrogen chloride and hydrogen fluoride. The activity of catalysts was tested in microreactor. The reaction variables were temperature, reactant composition and reactant flow rate. The reaction temperature affected on reaction severely. But the effects of reactant composition and reactant flow rate on reaction were mild. Nitrogen and carbon dioxide was adsorbed on catalysts to characterize catalysts. Specific surface area (nitrogen, BET eqn.), narrow micropore volume (carbon dioxide, Dubinin-Radushkevich eqn.), total micropore volume (nitrogen, alphas plot), total pore volume area (nitrogen, Gurvitsch eqn.) was calculated.
