“…Another key heteroatom that must be removed is nitrogen, because the NO x produced via combustion can have a negative effect on engine performance, engine emissions, exhaust gas temperature, combustion quality, and fuel economy . The hydrodenitrogenation (HDN) efficiency % is calculated as the feed nitrogen % loss, considering also liquid recovery as it is depicted in the following equation:

H D N (%) = \frac{N_{F e e d} − \frac{N_{P r o d u c t}}{R}}{N_{F e e d}} \cdot 100

where N Feed and N Product are the nitrogen wt% content in feed and product respectively, and R is the liquid recovery as described in Equation (1).…”

The aim of this study is to investigate the effect of CO2 on catalytic hydrotreatement of gas‐oil to evaluate the potential of catalytic co‐ hydroprocessing of petroleum fractions with liquid biomass. A total of six experiments were conducted under low (330 °C), mild (345 °C) and severe (360 °C) operating conditions employing straight run gas‐oil as the petroleum fraction feedstock. During three of these experiments CO2 was artificially added to the reaction system to assess its impact on the associated catalytic reactions over a commercial CoMo/Al2O3 catalyst. The dedicated experiments revealed a suspending role of CO2 on hydro‐ desulfurization (HDS), hydro‐denitrogenation (HDN), and saturation reactions, which is attributed to the subsequent hydrogen partial pressure reduction of the reacting system caused by the competitive water gas‐shift and methane reforming reactions.

“…In our previous studies, it was demonstrated that metal ionmodified silica adsorbents showed high adsorptive and regenerative performances in the desulfurization and denitrogenation of a raw diesel fuel [5,19,20]. It was also determined from the breakthrough results that the sorption rate is equally important as the sorption capacity.…”
