Abstract
A process is described for removing both high polar and neutral nitrogen compounds from petroleum processing liquid products and petroleum distillate fractions. According to the novel feature, a chlorosilylated silica gel is used as adsorbent for the nitrogen compounds. This adsorbent has been found to be superior to regular silica gel and commercial ion exchange resins for removing particularly the neutral nitrogen compounds.
