摘要： The present invention provides a process for natural gas in the form, e.g., of stranded gas or associated gas to transportable liquids. More particularly, the present invention provides a process in which the gas is non-oxidatively converted to aromatic liquid, preferably in proximity to the welihead, which may be onshore or offshore. In one aspect, the present invention provides integration of separation of wellhead fluids into associated gas and crude with blending of the aromatic liquid derived from the gas with the crude. Alternatively, or in combination, in another aspect, the present invention provides integration of conversion of byproduct hydrogen to power with non-oxidative conversion of gas to aromatic liquid.

摘要： The present invention is generally related towards enhancing the yield and/or cold-flow properties of certain hydrocarbon products, increasing the degree of isomerization in a diesel product and/or increasing the production rate of a diesel product. The embodiments generally include reducing the residence time of lighter hydrocarbon fractions during hydrocracking, thereby decreasing secondary cracking, by various configurations of introducing at least two hydrocarbon feedstreams of different boiling ranges at different entry points in a hydrocracking unit. A method further includes forming a hydrocarbons stream comprising primarily C5+ Fischer-Tropsch hydrocarbon products; fractionating hydrocarbons stream to form at least a wax fraction and an intermediate fraction which serve as separate feedstreams to a hydrocracking unit comprising at least two hydroconversion zones. One embodiment comprises the use of a bifunctional catalyst in one of the hydrocracking zones so as to favor hydroisomerization of hydrocarbons to favor the formation of branched paraffins boiling in the diesel range.

摘要： Methods for producing clean liquid/wax products from a slurry used in a Fischer-Tropsch reactor are disclosed. In general, one embodiment of the present invention comprises a solid/liquid filtration system having a filter medium comprising a substrate and a filter cake deposited on the substrate, wherein the filter cake is generated by deposition of solids from the slurry. The thickness of the filter cake can be maintained within a desired range by controlling the slurry velocity and/or the pressure differential across the filter medium. This invention relates to a method of operation of such filtration system which increases filtration cycle time and improved filtrate quality resulting in very low solid content in filtrate.

摘要： Methods and apparatus for removing wax products from a slurry used in a Fischer-Tropsch reactor. The preferred embodiments of the present invention are characterized by a solid/liquid separation system that removes liquid products from a slurry by drawing the fluid across a filter medium composed of a filter cake disposed on a substrate. In the preferred embodiments, the filter cake is desirable and performs the majority of the filtration. In certain embodiments, the filter medium is disposed in a filter housing where slurry flows parallel to the longitudinal axis of the filter medium from and inlet to an outlet. The characteristics or properties of the cake, which will effect the performance of the solid/liquid separation system, can be controlled by regulating the velocity of the slurry flowing across the cake, where the velocity may be regulated by adjusting the slurry flow through the filter housing or may be self-regulated by changing slurry velocities influenced by the design of the filter housing.

摘要： A process for reducing C2-C9 olefin formation by recycling them to a Fischer-Tropsch hydrocarbon synthesis process and promoting recycled olefins chain growth comprises contacting a gas feed comprising a mixture of H2 and CO with a catalyst in a reactor system at conditions effective to produce a hydrocarbon product stream including C2-C9 olefins, separating a C2-C9 olefins-rich stream from the hydrocarbon product stream to form a light olefin recycle stream and recycling the light olefin recycle stream to the reactor system at a point in the reactor system where the H2:CO ratio is low relative to the H2:CO ratio in the rest of the reactor system. Depending on whether the initial H2:CO ratio is greater or less than the usage ratio of the selected catalyst, the recycled olefins can be returned to the system up- or downstream of the reactor system.
