Definitions

  • the invention is directed to a process to prepare Fischer-Tropsch derived medicinal and technical white oils.
  • the medicinal white oils preferably have a kinematic viscosity at 100 °C of above 8.5 cSt.
  • Applicants have developed a new process, which is capable of preparing various base oil grades, including high viscosity grades, simultaneously from a relatively heavy Fischer-Tropsch synthesis product.
  • a Fischer-Tropsch synthesis product is for example obtainable with the process as described in WO-A-9934917.
  • the new process comprises hydroprocessing of said feed and preferably followed by a pour point reducing step.
  • a process is for example described for a different feed in Example 3 of EP-A-776959.
  • the fraction obtained using the more heavier feedstock can in turn be separated by means of distillation, at reduced pressure, into a heavy base oil grade having a kinematic viscosity at 100 °C of at least 8.5 cSt and one or more base oil grades having a kinematic viscosity at 100 °C of between 2 and 7 cSt.
  • the heavy base oil grade which has properties equal or close to those of a technical white oil, will be obtained in a high yield as the bottom product of the distillation.
  • Technical and Medicinal white oils are characterized in that they have no colour.
  • Technical white oils have a Saybolt colour (ASTM D-156) of greater than +20.
  • Medicinal white oils have a Saybolt colour of greater than +25, more particularly equal to +30.
  • Other medicinal and technical white oil specifications are a low UV adsorbance at different UV spectral ranges according to for Example FDA 178.3620 (b) and FDA 178.3620 ('c) respectively.
  • Medicinal white oils for use in food applications further need to have a kinematic viscosity at 100 °C greater than 8.5 cSt and a 5%w boiling point greater than 391 °C.
  • the invention is therefore directed to the preparation of medicinal white oil or a technical white oil from a Fischer-Tropsch derived paraffinic distillate bottom product, wherein said bottom product is contacted with a heterogeneous adsorbent.
  • heterogeneous adsorbents are active carbon, zeolites, for example natural faujasite, or synthetic materials such as ferrierite, ZSM-5, faujasite, mordenite, metal oxides such as silica powder, silica gel, aluminium oxyde and various clays, for example Attapulgus clay (hydrous magnesium-aluminium silicate), Porocel clay (hydrated aluminium oxide).
  • a preferred adsorbent is activated carbon.
  • activated carbon is a microcrystalline, nongraphitic form of carbon, which has been processed to develop internal porosity due to which it has a large surface area.
  • Activated carbons which have been found particularly suitable, are those having a surface area (N 2 , BET method) in the range from 500 to 1500 m 2 /g, preferably from 900 to 1400 m 2 /g, and a Hg pore volume in the range from 0.1 to 1.0 ml/g, preferably from 0.2 to 0.8 ml/g.
  • Hg pore volume is meant the pore volume as determined by mercury porosimetry.
  • activated carbons which additionally have a micropore size distribution of 0.2 to 2 nm with an average of 0.5 to 1 nm, a pore size distribution (Hg porosimetry) in the range from 1 to 10,000 nm, preferably from 1 to 5,000 nm, and a total pore volume as determined by nitrogen porosimetry in the range from 0.4 to 1.5 ml/g, preferably from 0.5 to 1.3 ml/g.
  • Other preferred physical characteristics include an apparent bulk density of from 0.25 to 0.55 g/ml, a particle size of from 0.4 to 3.5 nm, preferably 0.5 to 1.5 nm, and a bulk crushing strength of at least 0.8 MPa, preferably at least 1.0 MPa.
  • suitable commercially available activated carbons include Chemviron type, Chemviron F-400 (FILTRASORB 400), DARCO GCL 8*30 and DARCO GCL 12*40 (FILTRASORB and DARCO are trade marks).
  • the activated carbon used in the process according to the present invention is preferably dry activated carbon.
  • the water content of the activated carbon should be less than 2% by weight, preferably less than 1% by weight and more preferably less than 0.5% by weight, based on total weight of activated carbon.
  • the conditions (temperature, pressure, space velocity) under which the bottom product is contacted with the activated carbon may vary within broad ranges in order to still attain an improved base oil quality. Temperatures in the range of from 20 to 300 °C, preferably 30 to 200 °C, more preferably 40 to 150 °C, have been found to be suitable in this respect.
