Chemisorption of n-Butylamine and n-Butylmercaptan on Fluoride-Modified CoMo/AlO Catalysts

Abstract

The chemisorption of n-butylamine (n-BA) and n-butylmercaptan (n-BM) on cobalt–molybdenum catalysts supported on alumina containing fluoride ions was studied. The active phases of the catalysts were introduced in two ways: either simultaneously or in two stages. It was shown that the chemisorption of n-BA increased with increasing concentration of fluoride ions, but no such relationship was observed for n-BM. The sequence in which fluoride ions and CoMo were introduced had no significant effect on the effectiveness of chemisorption.
