Simultaneous hydrodenitrogenation and hydrodeoxygenation of model compounds in a trickle bed reactor
In selected binary mixtures of a heterocyclic nitrogen compound and a phenolic or heterocyclic oxygen compound and in the presence of H/sub 2/S, the rate of hydrodeoxygenation (HDO) was considerably decreased in comparison to that observed with the same compound individually at the same reaction conditions. In mixtures, the rate of hydrodenitrogenation (HDN) of quinoline was increased and the effect on the HDN rate of o-ethylaniline depended on the specific oxygen compound. Small concentrations of water vapor increase hydrodenitrogenation, especially if H/sub 2/S is also present. In the hydrodeoxygenation of an ethyl phenol, substantial quantities of an ethyl cyclohexene are formed as an intermediate. The final products are ethylcyclohexane and ethylbenzene, the former predominating. 14 figures.
