Definitions

  • Figure 2 is an illustration of a process for making alkylaromatics and alkylcycloparaffms from Fischer Tropsch products with additional alkylaromatics generated by alkylation of light aromatics.
  • the highly paraffinic distillate fuel component and the distillate-boiling alkylaromatics and distillate-boiling alkylcycloparaffms are obtained from products of a Fischer Tropsch process.
  • processes are disclosed which utilize Fischer Tropsch-derived products to obtain the highly paraffinic distillate fuel component and the distillate-boiling alkylaromatics and alkylcycloparaffms.
  • light boiling Fischer Tropsch products are converted into distillate fuel, thus increasing the yield of fuel from the Fischer Tropsch process.
  • a stream comprising a Fischer Tropsch product boiling lighter than the desired distillate fuel is fed to an oligomerization zone containing an oligomerization catalyst and is subjected to oligomerization under oligomerization conditions.
  • the resulting oligomerized product is then fed to a hydrogenation zone containing a hydrogenation catalyst and is subjected to hydrogenation under hydrogenating conditions.
  • the highly paraffinic distillate fuel component may be prepared, for example, by oligomerizing a feedstock of light olefins and/or alcohols, and hydrogenating the resulting oligomers.
  • These light olefins and/or light oxygenates are preferably obtained from a Fischer Tropsch process.
  • the light olefins can be obtained by thermally cracking Fischer Tropsch products, especially non-distillate boiling Fischer Tropsch products.
  • the distillate-boiling Fischer Tropsch product is fed to isomerization zone 50 where isomerization takes place under isomerizing conditions in the presence of hydrogen and a catalyst to produce highly paraffinic distillate fuel.
  • the resulting product of the isomerization zone preferably is a highly paraffinic distillate fuel containing more than about 70 wt. % paraffins, preferably more than 80 wt. % paraffins, and most preferably more than 90 wt. % paraffins.
  • isomerization of the distillate-boiling Fischer Tropsch product is done by contacting the product with hydrogen in the presence of a hydroisomerization dewaxing catalyst.
  • Suitable catalysts include noble metals from Group VIIIA (according to the 1975 rules of the International Union of Pure and Applied Chemistry), such as platinum or palladium on an alumina or siliceous matrix, and unsulfided Group VIIIA and Group VIB, such as nickel-molybdenum or nickel-tin on an alumina or siliceous matrix.
  • the non-noble metal (such as nickel-molybdenum) hydrogenation metals are usually present in the final catalyst composition as oxides, or more preferably or possibly, as sulfides when such compounds are readily formed from the particular metal involved.
  • Suitable matrix materials may also include synthetic or natural substances as well as inorganic materials such as clay, silica and/or metal oxides such as silica-alumina, silica-magnesia, silica-zirconia, silica-thoria, silica- berylia, silica-titania as well as ternary compositions, such as silica-alumina-thoria, silica-alumina-zirconia, silica-alumina-magnesia, and silica-magnesia zirconia.
  • the latter may be either naturally occurring or in the form of gelatinous precipitates or gels including mixtures of silica and metal oxides.
  • Catalytic reforming or AROMAX® technologies may be used to convert the reformable Fischer Tropsch product or a hydrotreated naphtha to aromatics.
  • Catalytic reforming is well known. For example, it is described in the book, Catalytic Reforming, by D. M. Little, PennWell Books (1985).
  • the AROMAX® Process is well known to those of skill in the art, and is described, for example, in Petroleum & Petrochemical International, Volume 12, No. 12, pages 65 to 68, as well as U.S. Patent No. 4,456,527 to Buss et al.
  • the reformable Fischer Tropsch product is fed to reforming zone 20 which contains a reforming catalyst.
  • distillate-boiling alkylaromatics stream optionally may be fed to a hydrogenation zone 30 in the presence of hydrogen 27 and subjected to hydrogenation in the presence of a catalyst and under hydrogenating conditions to form distillate-boiling alkylcycloparaffms 33.
  • the portion of distillate-boiling alkylaromatics not hydrogenated and the distillate-boiling alkylcycloparaffms produced then may be blended with the highly paraffinic distillate fuel in a blending zone to form a blended distillate fuel with improved seal swell properties and improved lubricity.
  • Figure 2 also shows an aspect of the invention wherein distillate-boiling alkylaromatics 149 are prepared by alkylation 110 of light aromatics 107 with light Fischer-Tropsch products containing olefins and/or alcohols 105.
  • Light aromatics refer to aromatic-containing streams that have a relatively light boiling range such that they cannot be blended into the distillate fuel without causing the fuel's flash point to drop below the specification minimum. The actual composition and boiling range of the light aromatics will depend on the specific distillate fuel (jet or diesel).
  • all or a portion of the alkylaromatics produced in separation/distillation zone 120 or reforming zone 140 may be fed to hydrogenation zone 150, in combination with hydrogen 147 and hydrogenated to form alkylcycloparaffinsl53 in hydrogenation zone 150.
  • the conditions of hydrogenation are well known in the industry and include reacting the alkylaromatic with hydrogen and a catalyst at temperatures above ambient and pressures greater than atmospheric.
  • the catalysts for use in hydrogenation zone 150 are those typically used in hydrotreating, but non-sulfided catalysts containing Pt and/or Pd are preferred, and it is preferred to disperse the Pt and/or Pd on a support, such as alumina, silica, silica alumina, or carbon.
  • a support such as alumina, silica, silica alumina, or carbon.
  • the preferred support is alumina.
  • Hydrogen for the hydrogenation can be supplied from the reforming zone 140, or from the synthesis gas used to produce the Fischer Tropsch product, or from steam reforming of methane-containing steams.
  • distillate-boiling alkylcycloparaffms produced in hydrogenation zone 150 may then be utilized in a distillate fuel blend with other products from the process of Figure 2, such as distillate-boiling alkylaromatics produced in reforming zone 140 or distillation zone 120 and highly paraffinic distillate fuel 175 obtained from isomerization zone 170.
  • the blending of these components may be conducted by any of the methods known to those of skill in the art.
  • the highly paraffinic distillate fuel component also generally will have a volume increase of less than about 0.2 %> when measured according to ASTM D 471 at 23 +/- 2°C and for 70 hours when using a nitrile O-ring seal.
  • the volume increase of the highly paraffinic distillate fuel will be less than about 0.5 % when measured according to ASTM D 471 at 23 +/- 2°C and for 70 hours when using a nitrile O-ring seal such as a Buna N Seal.
  • ASTM D 471 is the test method which covers the required procedures to evaluate the comparative ability of rubber and rubber-like compositions to withstand the effect of liquids.
  • the highly paraffinic distillate fuel component will contain more than about 70 weight % of paraffins.
  • the highly paraffinic distillate fuel component will contain more than about 80 weight %> paraffins and most preferably more than about 90 weight % paraffins.
  • the distillate fuel blend typically will exhibit a volume increase of more than 0.2 % when measured according to ASTM D 471 at 23 +/- 2°C and for 70 hours when using a nitrile O-ring seal.
  • the distillate fuel blend will exhibit a volume increase of more than 0.5 % when measured according to ASTM D 471 at 23 +/- 2°C and for 70 hours when using a nitrile O-ring seal.
  • the distillate fuel blend will exhibit a volume increase of more than 1.0 %> when measured according to ASTM D 471 at 23 +/- 2°C and for 70 hours when using a nitrile O-ring seal.
