Title:
転化/水素化異性化とそれに続く接触脱パラフィンにより基油および中間溜出物を製造するための改良された融通性のある方法
Document Type and Number:
Japanese Patent JP4224637
Kind Code:
B2
Abstract:
For producing very high quality base stock and for simultaneously producing high quality middle distillates, successive hydroisomerisation and catalytic dewaxmg steps are employed wherein the hydroisomerisation is carried out in the presence of a catalyst containing at least one noble metal deposited on an amorphous acidic support, the dispersion of the metal being 20%-100%. The support is preferably an amorphous silica-alumina. Catalytic dewaxing is carried out in the presence of a catalyst containing at least one hydrodehydrogenating element (group VIII) and at least one molecular sieve selected from ZBM-30, EU-2 and EU-11.
