Abstract
A novel catalytic process involving complete hydrodehalogenation of halogenated aliphatic hydrocarbons in the presence of a hydrogen donor and a modified zeolite catalyst has been developed. The process is operated in a continuous flow mode and reaction products consist exclusively of hydrogen halide and hydrocarbons. The relative ratio of paraffins to olefins to aromatics obtained in the product distribution is a strong function of the ratio of hydrogen to reactant and the space velocity and temperature employed. The catalyst employed is a nickel metal modified shape selective zeolite that takes advantage of the hydrogenolysis ability of nickel and the acidic-shape selective properties of the zeolite.
