Everything else being equal, organic nitrogen in the feed will reduce the activity of the catalyst. If hydrocracking is reduced and conversion to aromatics does not decline, the reactor delta T will increase. Examine your light ends yield to determine if hydrocracking is up or down.
Low chloride on catalyst will reduce hydrocracking and result in higher delta T if temperature is increased to maintain conversion to aromatics.
The above assumes no change in feed PONA.
