The hydrodechlorination of CH2Cl2, CHCl3, and their mixtures catalyzed by a Pt-Co/C catalyst has been investigated in an effort to elucidate the chemistry associated with the generation of hydrocarbon oligomerization products. Both saturated and unsaturated C2 + hydrocarbons were observed with all three reaction mixtures, with the selectivity following the order CH2Cl2 + H2 < CHCl3 + H2 < CH2Cl2 + CHCl3 + H2. The results suggest that C2 + paraffins are formed by means of the alkyl mechanism of hydrocarbon chain growth; whereas, the alkenyl mechanism is responsible for olefin formation.
