“…A two-step hydrotreatment process, with deoxygenation of triglycerides and isomerization of the obtained n-alkanes being conducted separately, has been commercialized by Neste Oil. Several studies used acid supports, e.g., complex metal oxides [12,13], zeolites [14,15], and Al-doped mesoporous materials [16,17], to improve the isomerization activity of catalysts. Taking into account the cost and process efficiency, however, combining deoxygenation and isomerization into a single step is highly desirable.…”

Catalysts based on metals (Pt, Pd) and metal oxides (NiO, Co 3 O 4 , MoO 3 , WO 3 ), supported on the surface of borate containing aluminum oxide (B 2 O 3 -Al 2 O 3 ), in the hydrocracking of sunflower oil at a tem perature of 400°C, a pressure 4.0 MPa and a mass hourly space velocity MHSV 5.0 h -1 are compared. H 2 TPR and IR spectroscopy of adsorbed CO and ESDR show that the hydrogenation catalyst components are Pt 0 and Pd 0 , a mixture of Ni 2+ + Ni 0 , Co 2+ + Co 0 , or a mixture of the highest and partially reduced oxides of Mo and W. It is established that catalysts containing Pt, Pd, NiO and Co 3 O 4 , ensure complete oil hydrode oxygenation. The main oxygen removal reactions in Pt and Pd systems are decarboxylation and hydrode carbonylation. For catalysts with NiO and Co 3 O 4 , characteristic reactions are reduction and methanation. The highest yield of the diesel fraction was obtained on Pt/B 2 O 3 Al 2 O 3 catalysts with metal contents of 0.3-1.0 wt %. Along with n alkanes, the diesel fractions obtained on these catalysts include cycloalkanes and iso alkanes (up to around 40 wt %) and aromatic hydrocarbons present in trace amounts. Hydrocracking on the Pt system at 400°C for 20 h with MHSV of 1.0 h -1 produces a diesel fraction with a yield of at least 82.0 wt % and the content of iso alkanes at least 76.1 wt %.

“…Pt/SAPO-11 catalyst: the research group made the preparation by dipping method [14]. The functionalized SAPO-11 carrier was impregnated in H 2 PtCl 6 solution with equal volume of 6 h, dried at room temperature for 15 h, dried at 110℃ for 4 h, calcined at 500℃ for 6 h, then cooled and ground to make 2%(WT) Pt/SAPO-11 catalyst [15,16]. The catalyst under 320℃/1MPa of hydrogen pressure was activated 6 h before using.…”

Absorption and scattering of laser radiation by the diffusion flame of aviation kerosene S V Gvozdev, A F Glova, V Yu Dubrovskii et al. Abstract. Biological aviation kerosene was produced by one-step catalytic hydrotreatment of waste lard oil over Pt/SAPO-11 in a high-pressure fixed bed micro reactor. The influence of reaction conditions such as temperature, pressure, hydrogen oil ratio, and space velocity on the deoxygenation rate, the selectivity of C 8 -C 16 hydrocarbons and the isomerization rate of C 8 -C 16 hydrocarbons have been investigated. The experimental results showed that the temperature of 400℃, pressure of 5 MPa, hydrogen oil ratio of 1000 and space velocity of 1.2 h -1 were the best experimental reaction conditions. Under these conditions, the conversion rate is 96.62%, the selectivity of C 8 -C 16 hydrocarbons is 50.25%, and the isomerization rate of C 8 -C 16 hydrocarbons is 35.68%.
