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.
1Five HAAs (HAA5), including monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid were analyzed. Total chlorine, pH and total organic carbon concentration were analyzed as well.مقالات ثبت شده در مهندسی شیمیnbsp;The catalytic cracking of high density polyethylene (HDPE) has been carried out at 500nbsp;deg;C in a conical spouted bed reactor with two ...
