    摘要: CO2 emissions from syngas conversion processes are reduced by use of a multi-stage Fischer-Tropsch reaction system. A process for the conversion of syngas using a Fischer-Tropsch reactor comprises forming a first syngas and reacting at least a portion of the first syngas in a Fischer-Tropsch reactor to form a first hydrocarbonaceous product and a second syngas. The second syngas is mixed with a hydrogen-containing stream to provide an adjusted syngas, at least a portion of which is reacted in a dual functional syngas conversion reactor to form a second hydrocarbonaceous product and a third syngas comprising a reduced amount of CO2 than was present in the adjusted syngas.

    摘要: Lube base stocks and lube stock compositions, as well as a process for preparing lube base stocks and lube stock compositions, are disclosed. The lube oils preferably have a viscosity index above about 115. The process involves obtaining feedstocks that have a 95% point below 1150° F. and feedstocks that have 95% point above 1150° F. The feedstocks that have a 95% point below 1150° F. are catalytically dewaxed, and the feedstocks that have 95% point above 1150° F. are solvent dewaxed. The resulting products can optionally be blended, and the base stocks can be combined with various additives to form lube oil compositions. Hydrotreatment can optionally be performed on the lube base stocks to remove olefins, oxygenates and other impurities. In one embodiment, one or more of the fractions are obtained from Fischer-Tropsch synthesis. One or more of the fractions can also be obtained from other sources, for example, via distillation of crude oil, provided that the fractions do not include appreciable amounts (i.e., amounts which would adversely affect the catalyst used for catalytic isodewaxing) of thiols or amines. The individual fractions can also include combinations of feedstocks, from Fischer-Tropsch and other sources.

    摘要: Light olefins including LPG contained in unreacted tail gas from a Fischer-Tropsch process are catalytically condensed using an acidic oligomerization/aromatization catalyst to form higher molecular weight C5+ products. Thus, C3-C4 olefins are readily separated from the tail gas and upgraded to more valuable products. In one embodiment, the condensation is conducted on a mixed gas stream of fresh synthesis gas and tail gas from a Fischer-Tropsch process. In another embodiment, the condensation is conducted on a syngas feed to a Fischer-Tropsch reactor and removes a significant portion of catalytically poisonous nitrogen compounds.

    摘要: A process for making a lube base stock wherein an olefinic feedstock is separated into a light olefin fraction and a medium olefin fraction. The light olefin fraction is contacted with a first oligomerization catalyst in a first oligomerization zone to produce a first product. Both the medium olefin fraction and the first product are contacted with a second oligomerization catalyst in a second oligomerization zone to produce a second product. The second product is separated into a light byproduct fraction and a heavy product fraction that includes hydrocarbons in the lube base stock range.

    摘要: Methods for removing sulfur from syngas in a Fischer-Tropsch reactor, and reactors including means for removing sulfur from syngas are disclosed. Sulfur-reactive metals can be used in the Fischer-Tropsch unit to sequester the sulfur. For example, the Fischer-Tropsch unit can be run in stages, using a sacrificial catalyst in a first stage to adsorb the sulfur. The Fischer-Tropsch reactor can include internal baffles that separate the reactor into zones, with a sacrificial catalyst in one or more of the zones, that can be easily sequestered and regenerated or replaced. Sulfur adsorbents can be placed in the inlet gas manifold. A portion of the Fischer-Tropsch catalyst can be converted into larger size pellets that do not fluidize with the finer grain Fischer-Tropsch catalyst and remain near the gas inlet where they adsorb and sequester the sulfur. These embodiments can be combined in any suitable manner to lower the sulfur concentration in the syngas feed. The resulting syngas feed preferably has a sulfur concentration less than 50 wppb, more preferably less than 15 wppb, and most preferably less than 1 wppb.
