The hydrodechlorination reactions of 1,3-dichloropropene, a component of the waste stream from epichlorohydrin manufacturing, were examined over a variety of catalysts in a packed-bed microreactor. The reactor operated between 7.5-9 Mpa and 325 degrees C and rates of hydrodechlorination were followed for up to 14 h. Pt/gamma-Al2O3 and Ni/SiO2-Al2O3 catalysts were found to exhibit significant activity and no signs of deactivation over the course of the experiments, while other catalysts such as NiMo/gamma-Al2O3 exhibited substantial deactivation. Activation energies for the disappearance of 1,3-dichloropropene over the Pt/gamma-Al2O3 and Ni/SiO2-Al2O3 catalysts were found to be consistent with other dechlorination reactions, approximately 80-120 kJ/mol (20-30 kcal/mol).
