Abstract:
1. A process for the hydrodenitrogenation of a liquid hydrocarbon feedstream in a reactor having a reactor volume in the presence of a catalyst comprising at least one Group VIII metal and at least one Group VIB metal, which feedstream has a boiling range of about 200° C. to about 550° C. and having a total nitrogen heteroatom concentration, denoted by N f , ranging from about 10 wppm to about 3000 wppm, which process comprises: a) measuring a total nitrogen concentration in the feedstream, N b) calculating the feed nitrogen factor as f c) incorporating the results into the following formula and determining the feed nitrogen index, FNI, where d) locating the FNI on a plot of FNI vs. N e) determining a hydrogen treat gas rate, TGR wherein when FNI lies in
