Definitions

  • the present invention relates to the field of producing traffic fuels and base oil components. More particularly, the invention relates to a method including hydrocracking and dewaxing of waxy feedstock for producing middle distillate fuel and lubricant base oil.
  • Cracking, and especially hydrocracking, is a well-known process in refinery used for cleaving larger hydrocarbon components into smaller short-chain hydrocarbons which are usable as traffic fuel components. Cracking is achieved by breaking the carbon-carbon bonds in the hydrocarbon chain of C15 to C45 typically in the presence of a cracking catalyst. The nature of the end produces is dependent on the nature of the feed and on the process conditions under which the process is carried out, such as temperature, pressure and the nature of the catalyst.
  • a widely used method for carrying out catalytic cracking of high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils is a fluid catalytic cracking (FCC) process, in which a powdered catalyst is employed.
  • the catalyst particles are suspended in a rising flow of a heavy gas oil feed to form a fluidized bed.
  • the feed is typically pre-heated and then sprayed into the base of the riser via feed nozzles to bring the feed in contact with the hot fluidized catalyst.
  • the temperature of a FCC cracker is typically between 500° C. and 800° C.
  • Hydrocracking of heavy hydrocarbons can also be achieved in a fixed bed hydrocracker.
  • the feedstock is fed downward through the catalyst bed together with hydrogen gas.
  • the catalyst is fixed onto particles, which can be of various sizes and forms providing an even and homogenous distribution of the feedstock and hydrogen gas and, further, maximum contact with the active catalyst.
  • the catalyst containing particles are fixed in layer or bed and the feedstock and hydrogen gas run through the layer.
  • fixed bed reactors typically contain several catalyst layers.
  • VGO vacuum gas oil
  • Hydrocarbon cracking is usually accompanied by a hydrogenation process, also called as hydrotreatment process.
  • the purpose of the hydrogenation is to remove heteroatoms, such as oxygen, sulphur and/or nitrogen, and also to saturate aromatics typically present in the hydrocarbon feed.
  • the hydrogenation process is typically performed before the actual hydrocracking process in order to ensure removal of hereroatoms and saturation of aromatics. In some cases hydrogenation also includes ring-opening functions. However, no substantial cleavage of hydrocarbons takes place in the hydrogenation step.
  • the preceding hydrogenation of the feedstock before hydrocracking ensures good hydrocracking performance and improves the yield of the products produced in the hydrocracking.
  • Waxes and slack waxes is a general term for feedstock comprising mainly paraffins.
  • the paraffins in waxes are typically saturated C15-C45 linear hydrocarbons (normal or n-paraffins). Waxes may also contain to some extent branched (isomerized or i-paraffins) and cyclic hydrocarbons.
  • Slack waxes are typically formed by a solvent dewaxing process of a waxy petroleum feed, such as a VGO stream. The solvent dewaxing process is typically performed by mixing a suitable solvent with the waxy petroleum feed, then cooling the mixture and separating the waxes as solid wax crystals, for example by filtration.
  • Waxes can also be produced by Fischer-Tropsch (F-T) process, in which gas containing carbon monoxide and hydrogen is reacted to form hydrocarbon of various chain lengths.
  • F-T process is widely used in gas-to-liquid (GTL) technologies where natural gas is used as a carbon source.
  • Biomass can also be used as the carbon source in the F-T process and it is then generally called biomass-to-liquid (BTL) technology.
  • Slack wax produced by solvent dewaxing contains varied amounts or impurities which makes the slack wax a low value product.
  • a catalytic dewaxing (cat-dewaxing) unit is a device where hydrocarbon feedstock is catalytically dewaxed, i.e. selectively cracked and isomerized.
  • a cat-dewaxing is generally called as VHVI (Very High Viscosity Index) unit since base oils with very high viscosity index are obtained in said unit.
  • VHVI Very High Viscosity Index
  • In the VHVI unit in order to improve the cold properties of a base oil, linear paraffins are isomerized to form branched paraffins (iso-paraffins). Also, cracking of hydrocarbons takes place to some extent.
  • U.S. 2004/0256287 A1 discloses a process of hydrocracking a waxy hydrocarbon feedstock, such as Fischer-Tropsch waxy hydrocarbons, in the presence of a hydrocracking catalyst.
  • the hydrocracking effluent is hydroisomerized in the presence of a hydroisomerization catalyst.
  • the hydroisomerization effluent is fractioned to provide a heavy fraction and a middle distillate fuel, and the heavy fraction is dewaxed to provide a lubricant base oil having a viscosity index greater than 130.
  • U.S. 2009/0065393 A1 discloses a method for obtaining a petroleum distillate in which a paraffin-based wax such Fischer-Tropsch wax and/or slack wax, is subjected to a cracking process in the presence of a catalyst, followed by hydrogenating the olefinic intermediate obtained in the presence of a catalyst and recovering the distillate.

  • a beneficial advantage of the method of the invention is that strict quality requirements of VGO as an adequate feedstock can be bargained when slack wax is introduced to the feedstock.
  • the adequate quality of the feedstock is adjusted by means of the VGO and slack wax. This means in practice that lower quality VGO with higher quality slack wax including a minor amount of impurities, and vice versa, can be used in the method of the invention and still high quality products are produced.

  • a high VI means that base oil has similar viscosity properties at 40° C. and at 100° C. which is a highly desired property.
  • Low VI is not desired; it means that base oil has high viscosity at 40° C. but low at 100° C.
