摘要：

Improved activity and activity maintenance have been demonstrated in the hydrodechlorination of chloroform to methylene chloride over commercial Pt/Al2O3 reforming catalysts. Continuous addition of water more than doubled the reaction rate by removing chloride from the alumina, thereby preventing excessive acidity and associated rapid coking. Two Pt/Al2O3 catalysts were tested of different metal content. Pt-Re/Al2O3 was also studied and, although not as active, deserves further consideration at other Pt-to-Re ratios. © 1979, American Chemical Society. All rights reserved.
