“…Ru was used as it is superior to Ni in hydrocracking reactions, and although other noble metals may exhibit similar activity to that of Ru, 38 they are more expensive. The selectivity toward methane production is, to the best of our knowledge, unprecedented under relatively mild conditions (i.e., T [temperature] 350 C-440 C, P total 60-100 bar, P hydrogen 20-55 bar) 39 and outperforms other reported catalysts. 40,41 Mechanistic studies show that the catalyst, composed of Ru NPs immobilized on a zeolite, operates via a different (Ru-dominant) mechanism to the general bifunctional (acid site and metal site) mechanism 42,43 usually observed for C-C bond hydrogenolysis.…”

“…Under stable conditions, the reaction runs at about 50 bars of H 2 with a reactor weight average bed temperature of 350 °C. A proper nitrogen stripping (80 mL min −1 ) ensures the removal of sulfurs species, which could poison the bi‐functional noble metal‐acid catalyst used in the subsequent isomerization‐cracking step (e.g., Pt/ZSM5) 45–51 …”

The 2 ha pilot-plant Seawater Energy and Agriculture System (SEAS) in Abu Dhabi, United Arab Emirates (UAE), integrates aquaculture ponds, which produce fish and shrimp, with fields of Salicornia and mangrove used as a natural filter to clean the waste seawater from the ponds. The SEAS is a sustainable solution that addresses the food security issues of countries with large deserts or arid regions. At the same time, it produces economically viable fuels from biomass, using non-arable lands and non-drinkable water. After harvesting and pressing Salicornia seeds (2 t ha −1 year −1 ), a custom-made process serves to pretreat the vegetable oil (0.7 t ha −1 year −1 ) containing 85 wt% C 18 and 10 wt% C 16 fatty acids as triglycerides. The first step of the UOP Ecofining ® process produces an oil composed of linear C 15 -C 18 alkanes. Analytical data suggest the oil feed converts at 60 wt% by hydrodeoxygenation and at 40 wt% through decarboxylation/decarbonylation. The subsequent hydrocracking/isomerization step provided 3.4 wt% C 1 -C 4 , 34.8 wt% green naphtha, 47.5 wt% sustainable aviation fuel (SAF), and 14.2 wt% green diesel. After distillation, the SAF has been certified following ASTM D7566 before being blended with conventional jet fuel and used successfully on a commercial passenger flight in January 2019. The techno-economic study shows that the biorefinery part is economically sustainable when reaching a production scale of 900bbd, required for a SEAS surface of 20 000 ha. At this scale, expected revenue and conversion costs per MT of

“…These processes play an important role in refineries. Since 1950, together with the development of the transportation industries, hydrocracking has become a promising technology to respond to the high demand for clean diesel in the road and railroad sector and for jet fuel in the aviation sector [2]. Furthermore, the availability of sufficient low cost hydrogen as a by-product from the catalytic reforming of naphtha was a key factor in the popularity of hydroprocessing.…”

Accelerating Kinetic Parameter Identification by Extracting Information from Transient Data: A Hydroprocessing Study Case

et al. 2020

Hydroprocessing reactions require several days to reach steady-state, leading to long experimentation times for collecting sufficient data for kinetic modeling purposes. The information contained in the transient data during the evolution toward the steady-state is, at present, not used for kinetic modeling since the stabilization behavior is not well understood. The present work aims at accelerating kinetic model construction by employing these transient data, provided that the stabilization can be adequately accounted for. A comparison between the model obtained against the steady-state data and the one after accounting for the transient information was carried out. It was demonstrated that by accounting for the stabilization, combined with an experimental design algorithm, a more robust and faster manner was obtained to identify kinetic parameters, which saves time and cost. An application was presented in hydrodenitrogenation, but the proposed methodology can be extended to any hydroprocessing reaction.
