摘要
Hydrodechlorination of 1,2,4-trichlorbenzene was carried out over ruthenium catalysts supported on gamma-Al2O3, CeO2, ZrO2, SiO2, SBA-15 and activated carbon. In the hydrodechlorination of 1,2,4-trichlorobenzene, higher catalytic activities and longer catalyst life was achieved for Ru catalysts supported on carbon compared to Ru catalysts supported on other supports. The higher catalytic activity exhibited by carbon supported ruthenium catalysts was attributed due to high dispersion of Ru, metal area and smaller crystallite size owing to strong chemisorption of 1,2,4-trichlorobenzene leading to complete hydrodechlorination.
