Co-processing of mixture, containing 30 wt.% of rapeseed oil (RSO) in straight run gas oil (SRGO), was studied over stacked bed sulfide catalytic system containing Mo/Al₂O₃ as a first layer and CoMo/Al₂O₃-SAPO-11 or NiMo/Al₂O₃-SAPO-11 catalyst as the second one. The experiments were performed in a trickle bed reactor at 350-380 °C, 4.0-7.0 MPa, 1.5 h^-1 and 1000 Nm³/m³. The hydrodeoxygenation (HDO) of RSO is proceeding over Mo/Al₂O₃ catalyst mostly through direct HDO route (selectivity > 93%). The proposed combination of catalysts minimizes the formation of carbon monoxide, that is known as an inhibitor of hydrotreating reactions and can affect the hydroisomerisation/hydrocraking of alkanes over CoMo/Al₂O₃-SAPO-11 and NiMo/Al₂O₃-SAPO-11 catalysts. The effects of temperature and pressure on the behavior of Mo/Al₂O₃-CoMo/Al₂O₃-SAPO-11 and Mo/Al₂O₃-NiMo/Al₂O₃-SAPO-11 systems were studied and the difference in the quality of products were discussed with the emphasis on the cold flow properties. The cloud point of products, obtained in the co-processing of RSO-SRGO mixture over Mo/Al₂O₃-CoMo/Al₂O₃-SAP and Mo/Al₂O₃-NiMo/Al₂O₃-SAP catalytic systems was decreased to −8 and −13 °C respectively with the temperature increase from 350 to 380 °C. In addition, the hydrogenated products produced over NiMo/Al₂O₃-SAP were characterized by lower final boiling point values and aromatic content in comparison with that produced over CoMo/Al₂O₃-SAP catalyst. Unexpectedly, the opposite effect of pressure was observed on the cloud point and the conversion of long chain alkanes, which were produced in hydrodeoxygenation of RSO.

在包含Mo / Al ₂ O ₃作为第一层和CoMo / Al _2的叠层硫化物催化体系上研究了在直馏瓦斯油（SRGO）中包含30 wt。％菜籽油（RSO）的混合物的共处理O ₃ -SAPO-11或NiMo / Al ₂ O ₃ -SAPO-11催化剂为第二催化剂。实验在滴流床反应器中于350-380°C，4.0-7.0 MPa，1.5 h ^-1和1000 Nm ³ / m ^3进行。RSO的加氢脱氧（HDO）在Mo / Al ₂ O _3上进行催化剂主要通过直接的HDO途径（选择性> 93％）。提议的催化剂组合可最大程度地减少一氧化碳的形成，一氧化碳被称为加氢处理反应的抑制剂，可影响烷烃在CoMo / Al ₂ O ₃ -SAPO-11和NiMo / Al ₂ O ₃ -SAPO上的加氢异构化/加氢裂化-11催化剂。温度和压力对Mo / Al ₂ O ₃ -CoMo / Al ₂ O ₃ -SAPO-11和Mo / Al ₂ O ₃ -NiMo / Al ₂ O _{3行为的影响}研究了-SAPO-11系统，并着重讨论了冷流特性，讨论了产品质量的差异。在Mo / Al ₂ O ₃ -CoMo / Al ₂ O ₃ -SAP和Mo / Al ₂ O ₃ -NiMo / Al ₂ O ₃ -SAP催化下RSO-SRGO混合物的共处理中获得的产物浊点随着温度从350升高到380°C，系统分别降至-8和-13°C。此外，与在CoMo / Al上生产的产品相比，在NiMo / Al ₂ O ₃ -SAP上生产的氢化产品的特征在于最终沸点和芳烃含量更低₂ O ₃ -SAP催化剂。出乎意料的是，在RSO加氢脱氧中产生的浊点和长链烷烃的转化中观察到了相反的压力作用。
