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： The present invention provides a process for managing hydrogen in a hydrocarbon gas to liquid plant. The process includes feeding a syngas stream produced by a partial oxidation reactor to a Fischer-Tropsch reactor, thereby converting the syngas to hydrocarbon liquids. It also includes passing a substantially oxygen-free feed stream comprising hydrocarbon gas and water to a steam reformer, thereby producing a hydrogen-rich stream. The H2/CO ratio in the syngas feed stream can be adjusted to a desired value by introducing a first portion of the hydrogen-rich stream to the syngas feed stream. A second portion of the hydrogen-rich stream can be passed to one or more hydrogen users, e.g., a catalyst regeneration unit, in the GTL plant.

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.
