Abstract

The hydrocracking of n-heptane has been studied in a continuous, tubular, plug flow reactor using a 4 wt NiO-8 wt% MoO/sub 3//HYUS zeolite as catalyst, to try to obtain a network of reactions to account for the formation of the various products observed. In view of the products obtained and depending on whether they are primary or secondary, a series of simultaneous parallel reaction schemes have been proposed to explain the network of the reaction. The kinetic parameters of these reactions have been obtained from the initial selectives of the products. The values of the apparent activation energies obtained for the isomerization, hydrogenolysis, cracking, and disproportionation reactions were 99.1, 169.6, 221.4, and 195.9 kJ/mol, respectively.
