摘要:
A process for production of very high-quality base oils, and simultaneous production of high-quality middle distillates, comprises the successive stages of hydroisomerization and catalytic dewaxing. The hydroisomerization takes place in the presence of a catalyst containing at least one noble metal deposited on an amorphous acid support, the metal dispersion being less than 20%. The support is preferably an amorphous silica-alumina. The catalytic dewaxing takes place in the presence of a catalyst containing at least one hydrodehydrogenating element (Group VIII) and at least one molecular sieve chosen from ZBM-30, EU-2, and EU-11.
摘要:
An improved process for producing very high quality base stock and for simultaneous production of high quality middle distallates, comprising successive hydroisomerisation and catalystic dewaxing steps wherein 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 less than 20%. 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 (preferably zeolite). The sieve is preferable selected from NU-10, EU-1, EU-13, zeolite and ferrierite.
摘要:
The invention concerns a process for producing gasoline with an improved octane number, optionally accompanied by oil and/or middle distillate production, by conversion-hydroisomerization of the paraffins in the feed using a catalyst containing at least one noble metal deposited on an amorphous acidic support. Isoparaffins are separated from the gasoline cut obtained, and normal paraffins and possibly monobranched paraffins contained in the resulting effluent are isomerized using a catalyst containing at least one hydrodehydrogenating metal and at least one acidic solid. The ensemble of the streams charged with isoparaffins with an improved octane number is sent to the gasoline pool. The residue undergoes catalytic dewaxing.

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.
