Гидрооблагораживание смесей прямогонной дизельной фракции с легким газойлем каталитического крекинга с использованием сульфидного NiMo катализатора на цеолитсодержащем носителе

A NiMo sulfide system with an alumina support containing aluminosilica phosphate SAPO-31 (catalyst NiMo/Al 2 O 3 -SAP) was suggested for synthesis of high-quality diesel fuel from a mixture of straight-run diesel fraction and light catcracking gasoil (LCCG). Against the traditional NiMo/Al 2 O 3 or CoMo/Al 2 O 3 sulfide catalysts, this catalyst was demonstrated to provide production of higher quality diesel fuel through hydroupgrading of the feedstock containing 30 wt.% LCCG. The fact that the proportion of aliphatic hydrocarbons is higher in the products than in the feedstock indicates the activity of the NiMo/Al 2 O 3 -SAP catalyst to ring opening. Application of the suggested catalyst will allow the quality of diesel fuels to be improved during hydroupgrading of the LCCG-containing feedstock.
