Abstract
AbstractThe decomposition of nitrogen‐containing compounds : 1,2,3,4 tetrahydroquinoline, 6‐methylquinoline, decahydroquinoline, orthopropylaniline and 2,6‐diethyl, l‐aniline, was studied at 623 K, 7 MPa in a continuous flow microreactor over two commercial nickel‐molybdenum‐alumina catalysts, (HR346 and HR348, Procatalyse). Decahydroquinoline was found to react very rapidly under the conditions of 1,2,3,4‐tetrahydroquinoline hydrodenitrogenation. The simultaneous transformations of quinoline and anilines showed that the aniline transformation was inhibited by the quinolines. However the inhibiting effect was much less significant with HR348 which also happens to be more active in aniline transformation.
