catalytic hydrodechlorination of monochloroacetic catalytic hydrodechlorination of monochloroacetic

Catalytic Hydroprocessing of Chlorinated Organics ...Recently, an in-process recycling (pollution prevention) alternative for managing chlorinated wastes has emerged - catalytic hydrodechlorination. This project addresses several of the technical roadblocks that impede commercialization of catalytic hydrodechlorination.

The optimal conditions for the reduction was determined to be 3% Pd loading, 0.9 mA·cm-2 current density and 1 g·L-1 catalyst dosage. Both of direct and indirect reduction could be facilitated by decreasing solution pH.
