  • Patent number: 10759722
    Abstract: Aspects of the invention are associated with the discovery of approaches for the conversion of sour natural gas streams, by conversion to liquid hydrocarbons. Particular processes and their associated apparatuses advantageously combine (i) dehydroaromatization (DHA) of methane in a gaseous feedstock, to produce aromatic hydrocarbons such as benzene, with (ii) the reaction of H2S and methane in this feedstock, to produce organic sulfur compounds such as carbon disulfide (CS2) and thiophene (C4H4S). A gaseous product having a reduced concentration of H2S is thereby generated. The aromatic hydrocarbons and organic sulfur compounds may be recovered in a liquid product. Both the gaseous and liquid products may be easily amenable to further upgrading. Other advantages of the disclosed processes and apparatuses reside in their simplicity, whereby the associated streams, including a potential gaseous recycle, generally avoid high partial pressures of H2S.

  • Patent number: 10738247
    Abstract: Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H2 and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO2. At least a second portion of the methane may be reacted with H2O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (?H) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Such dry reforming (reaction with CO2 only) or CO2-steam reforming (reaction with both CO2 and steam) processes are advantageously integrated with Fischer-Tropsch synthesis to yield liquid hydrocarbon fuels. Further integration may involve the use of a downstream finishing stage involving hydroisomerization to remove FT wax.

  • Publication number: 20200087144
    Abstract: Processes and catalysts for producing hydrogen by reforming methane are disclosed, which afford considerable flexibility in terms of the quality of the reformer feed. This can be attributed to the robustness of the noble metal-containing catalysts described herein for use in reforming, such that a number of components commonly present in methane-containing process streams can advantageously be maintained without conventional upgrading (pretreating) steps, thereby improving process economics. This also allows for the reforming of impure reformer feeds, even in relatively small quantities, which may be characterized as complex gas mixtures due to significant quantities of non-methane components. A representative reforming catalyst comprises 1 wt-% Pt and 1 wt-% Rh as noble metals, on a cerium oxide support.

  • Publication number: 20200032146
    Abstract: Processes and catalyst systems are disclosed for performing Fischer-Tropsch (FT) synthesis to produce C4+ hydrocarbons, such as gasoline boiling-range hydrocarbons and/or diesel boiling-range hydrocarbons. Advantageously, catalyst systems described herein have additional activity (beyond FT activity) for in situ hydroisomerization and/or hydrocracking of wax that is generated according to the distribution of hydrocarbons obtained from the FT synthesis reaction. This not only improves the yield of hydrocarbons (e.g., C4-19 hydrocarbons) that are useful for transportation fuels, but also allows for alternative reactor types, such as a fluidized bed reactor.

At least a second portion of the methane may be reacted with H2O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (?H) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Catalysts for such processes advantageously possess high activity and thereby can achieve significant levels of methane conversion at temperatures below those used conventionally under comparable conditions. These catalysts also exhibit high sulfur tolerance, in addition to reduced rates of carbon (coke) formation, even in the processing (reforming) of heavier (e.g., naphtha boiling-range or jet fuel boiling-range) hydrocarbons. The robustness of the catalyst translates to high operating stability.

  • Patent number: 9963399
    Abstract: Aspects of the invention are associated with the discovery of processes for converting methane (CH4), present in a methane-containing feedstock that may be obtained from a variety of sources such as natural gas, to higher hydrocarbons (e.g., C4+ hydrocarbons) such as gasoline, diesel fuel, or jet fuel boiling-range hydrocarbons, which may optionally be separated (e.g., by fractionation) for use as transportation fuels, or otherwise as blending components for such fuels. Particular aspects of the invention are associated with advantages arising from maintaining reaction conditions that improve the yield of C4+ hydrocarbons. Further aspects relate to the advantages gained by integration of the appropriate reactions to carry out the methane conversion, with downstream separation to recover and recycle desirable components of the reaction effluent, thereby improving process economics to the extent needed for commercial viability.

  • Publication number: 20080035528
    Abstract: A process for producing olefins from a feedstock comprising a petroleum and non-petroleum fraction has been developed. The process comprises first pretreating the feedstock to remove contaminants such as alkali metals and then cracking the purified feedstock in a fluidized catalytic cracking (FCC) zone operated at conditions to provide C2-C5 olefins. Alternatively, the non-petroleum fraction can first be treated and then mixed with petroleum fraction to provide the feedstock which is then catalytically cracked.

  • Publication number: 20060264684
    Abstract: A process has been developed for producing diesel fuel from biorenewable feedstocks such as plant oils and greases. The process involves a pretreatment step to remove contaminants such as alkali metals from the feedstock. Next the treated feedstock is hydrogenated and deoxygenated, i.e. decarboxylated and/or hydrodeoxygenated to provide a hydrocarbon fraction useful as a diesel fuel. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties.
