Smegal, J A

This patent describes a process for the hydrodenitrification of nitrogen-containing hydrocarbons in a hydrocarbon feedstock having a nitrogen content greater than about 100 parts per million by weight. It comprises contacting at a temperatures between about 575{degrees} F and about 775{degrees} F and a pressure between about 600 psi and about 2500 psi in the presence of added hydrogen the feedstock with a first catalyst bed containing a hydrotreating catalyst comprising nickel and tungsten supported on an alumina support, and passing the hydrogen and feedstock without modification, from the first catalyst bed to a second catalyst bed where it is contacted at a temperature between about 575{degrees} F and about 775{degrees} F and a pressure between about 600 psi and about 2500 psi with a hydrotreating catalyst comprising nickel and molybdenum supported on an alumina support.
