摘要： A process for reverse isomerization of a light naphtha feedstock containing branched C5-C7 paraffins. The process includes feeding a mixed feed stream including the light naphtha feedstock to a separation unit to generate an iso-paraffin stream and one or more normal paraffin streams. The process further includes mixing hydrogen gas and a hydrocarbon feed stream containing the iso-paraffin stream to form a hydrogen-enriched liquid feed stream which is provided to a reverse isomerization reactor. The hydrogen-enriched liquid feed stream is contacted with a solid reverse isomerization catalyst for reverse hydroisomerization in a substantially two-phase liquid-solid reverse isomerization fixed-bed reaction zone convert iso-paraffins to normal paraffins. The isomerization effluent stream is provided to a stabilization column to generate a stabilized isomerate stream which is combined with the light naphtha feedstock to generate the mixed feed stream. An associated system for performing the process is also provided.

摘要： The present technology provides processes for improving the performance of downstream oil conversion. Thus it provides, among others, processes for improving the yield of liquid hydrocarbons from a thermal conversion process. The processes include contacting a hydrocarbon feedstock with an effective amount of sodium metal and an effective amount of exogenous capping agent at a temperature of 250-500° C., to produce a mixture of sodium salts and a converted feedstock. The hydrocarbon feedstock may comprise hydrocarbons with a sulfur content of at least 0.5 wt %, an asphaltene content of at least 1 wt % and micro carbon residue content of at least 5 wt %. The converted feedstock may comprise hydrocarbons with a sulfur content less than that in the hydrocarbon feedstock, a micro carbon residue content less than that in the hydrocarbon feedstock and an asphaltene content less than that in the hydrocarbon feedstock. The process further comprises subjecting the converted feedstock to a thermal conversion process to produce a gaseous product, a purified product and a residual product, wherein the proportion of purified product to residual product is greater than that produced by subjecting the hydrocarbon feedstock in the same thermal conversion process.

摘要： Pathways are disclosed for the production of liquid hydrocarbon products comprising gasoline and/or diesel boiling-range hydrocarbons, and in certain cases renewable products having non-petroleum derived carbon. In representative processes, a gaseous feed mixture comprising CO2 in combination H2 and/or CH4 (or other hydrocarbon source of H2) is converted by reforming and/or reverse water-gas shift (RWGS) reactions, optionally further in combination with Fischer-Tropsch (FT) synthesis and/or cracking. A preferred gaseous feed mixture comprises biogas or otherwise a mixture of CO2 and H2 that is not readily upgraded using conventional processes. Catalysts described herein have a high activity for catalyzing the reforming (including dry reforming) of CH4 and other light hydrocarbons (e.g., those having been produced via FT synthesis and recycled as light ends back to the process) as well as simultaneously catalyzing the RWGS reaction. These attributes allow for flexibility in terms of compositions that may be converted efficiently. Economics of small-scale operations may be improved, if necessary, using an electrically heated reforming reactor in the first or initial reforming stage or RWGS stage.

摘要： The present technology relates to processes for converting PBWO into light and medium distillate such as usable diesel fuel, the processes generally comprising the steps of: boiling the PBWO to dehydrate the PBWO, heating the PBWO to produce PBWO hydrocarbon vapor, contacting the PBWO hydrocarbon vapor with a catalyst, and cooling the resultant vapor to liquid form through heat exchangers to produce light and medium distillate.

摘要： A method of removing oxygenates from a hydrocarbon stream comprises passing a hydrocarbon stream to a caustic tower having a plurality of loops, contacting the hydrocarbon stream with a sulfided catalyst between a first loop of the plurality of loops and a second loop of the plurality of loops to produce a reaction product, passing the reaction product to the second loop, removing at least a portion of the hydrogen sulfide in the second loop of the caustic tower to produce a product stream, and separating the product stream into a plurality of hydrocarbon streams in a separation zone located downstream of the caustic tower. The hydrocarbon stream comprises hydrocarbons, oxygen containing components, and sulfur containing compounds. At least a portion of the sulfur compounds react in the presence of the sulfided catalyst to produce hydrogen sulfide in the reaction product.

摘要： Embodiments provide a method and apparatus for recovering components from a hydrocarbon feedstock. According to at least one embodiment, the method includes supplying a hydrocarbon feedstock to an oxidation reactor, wherein the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds and nitrogen compounds present in the hydrocarbon feedstock, separating the hydrocarbons, the oxidized sulfur compounds, and the oxidized nitrogen compounds by solvent extraction, collecting a residue stream that includes the oxidized sulfur compounds and the oxidized nitrogen compound, and supplying the first residue stream to a fluid catalytic cracking unit. The first residue stream is further supplied through a hydrotreater prior to supplying the first residue stream to the fluid catalytic cracking unit.

摘要： Methods and apparatuses are provided for cracking a hydrocarbon. The method includes contacting a first hydrocarbon stream with a cracking catalyst in a riser. The cracking catalyst is regenerated in a regenerator to produce a flue gas stream having a particulate concentration, where the flue gas stream is vented. A second stream is contacted with the cracking catalyst in the riser while the first hydrocarbon stream is contacted with the catalyst, where the second stream includes a natural oil. The particulate concentration is a second particulate concentration while the second stream contacts the cracking catalyst, and a first particulate concentration prior to the second stream contacting the cracking catalyst. The first particulate concentration is greater than the second particulate concentration.
