The upgrading yields products in a gasoline, distillate, lube oil or wax range without requiring purification or compression of the gas mixture prior to feeding the gas mixture to a reactor. In operation, the mixture contacts a solid oligomerization catalyst, such as silica supported chromium, within the reactor. This contact occurs at a first temperature suitable to produce oligomers that are formed of the olefins and adsorb on the catalyst in liquid or solid phases. Next, heating the catalyst to a second temperature higher the first temperature desorbs the oligomers that are recovered and separated into the products.

  • Publication number: 20110319689
    Abstract: A process for producing hydrocarbon products, including: a) operating a process unit comprising a liquid catalyst in a first mode; b) adjusting a molar ratio of olefin to HCl; and c) operating in a second mode; wherein the first mode and the second mode are different, and the first mode and the second mode are selected from a distillate mode and a lubricant mode. Also, a process for making distillate and lubricant, including: adjusting a molar ratio of olefin to HCl in an oligomerization reactor to provide product selectivity; wherein decreasing the molar ratio provides a higher amount of distillate and increasing the molar ratio provides a higher amount of lubricant. Additionally, a process unit, having: a) an oligomerization reactor; and b) a control system that enables the reactor to be operated in a distillate mode and in a lubricant mode; and wherein the reactor can switch between modes.

  • Patent number: 7989668
    Abstract: Nitrogen-containing Lewis bases act as poisons for molecular sieve catalysts used in oligomerisation reactions. A lowering of their presence in the feed prior to the contacting thereof with the molecular sieve brings a significant extension of catalyst life. Excessive elimination of these poisons may be disadvantageous. Lowering the levels of these catalyst poisons to more manageable concentrations is therefore preferred.

    Abstract: In oligomerizing alpha-olefins to produce poly alpha-olefins, the feedstock consists of nonene, or a blend of alpha-olefins comprising nonene. The nonene comprising alpha-olefin feedstock and at least one catalyst are subjected to oligomerization or polymerization conditions in a reactor. Following reaction, the mixture may be subjected to distillations to removed unreacted alpha-olefins and dimers of the alpha-olefins. The resulting product may also be hydrogenated. The final product may also be fractioned to recover at least two fractions of poly alpha-olefins of differing nominal viscosities.

  • Patent number: 7880046
    Abstract: Water reacts on molecular sieve catalysts used in oligomerization reactions and forms oxygenated compounds, in particular organic acids that may cause corrosion problems downstream of the reactor, in particular in distillation tower overhead systems and downstream thereof. A lowering of the presence of water in the feed prior to contacting thereof with the molecular sieve brings a significant reduction in corrosion downstream. At the same time, it has a significant beneficial effect on catalyst activity and brings a significant extension of catalyst life. Lowering water in the feed is particularly effective when organic nitrogen-containing Lewis bases are present in the feed, even at low levels.
