Abstract: A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes contacting a gamma alumina catalyst support material with a first solution containing a vanadium compound, to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 500° C. The calcined modified catalyst support has a pore volume of at least 0.35 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support loses no more than 15% of its pore volume when exposed to water vapor. The modified catalyst support is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component to obtain a catalyst precursor. The catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer-Tropsch catalyst. The catalyst has enhanced hydrothermal stability as measured by losing no more than 22% of its pore volume when exposed to water vapor.

Abstract: A process and system are described for the processing of gas associated with crude oil production, i.e. associated gas. A separation complex is used to separate produced fluids produced from a hydrocarbon reservoir into crude oil, liquefied petroleum gas, water, and natural gas. At least a portion of the natural gas is converted into synthesis gas in a synthesis gas generator. A combination of a synthesis gas conversion catalysts and hydroconversion catalysts are used in a synthesis gas reactor to convert the synthesis gas into a liquid effluent stream containing liquefied petroleum gas and a synthetic crude oil. The liquefied petroleum gas and synthetic crude oil from the synthesis gas reactor is sent to the separation complex. Liquefied petroleum gas is separated both from the synthetic crude oil and a natural crude oil obtained from the produced fluids. The system and process permits synthetic crude oil to be blended with the natural crude oil producing a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil and with a pour point of 60° C. or less. Use of a common facility for separation operations on the natural crude oil and synthetic crude oil thus reduces capital costs and allows converted associated gases to be shipped with the natural crude oil on a conventional crude oil tanker.

Abstract: This invention relates to catalysts comprising a catalytic metal deposited on a composite support with well-dispersed chemical “anchor” species acting as nucleation centers for catalytic metal crystallites growth. The catalysts have the advantage that the average catalytic metal crystallite size can be controlled by the molar ratio of catalytic metal to chemical “anchor,” and is not limited by the porous structure of the support. A preferred embodiment comprises a cobalt-based catalyst on a silica-alumina support made by a co-gel method, wherein its average pore size can be controlled by the pH. The alumina species in the support most likely serve as chemical “anchors” to control the dispersion of cobalt species, such that the average cobalt crystallite size can be greater than the average pore size.

Abstract translation: 本发明涉及包含沉积在复合载体上的催化金属的催化剂，其具有充分分散的作为催化金属微晶生长的成核中心的化学“锚”物质。 催化剂的优点在于，催化金属的平均催化金属粒度可以通过催化金属与化学“锚”的摩尔比来控制，并不受支持体的多孔结构的限制。 优选的实施方案包括在通过共凝胶法制备的二氧化硅 - 氧化铝载体上的钴基催化剂，其中其平均孔径可以由pH控制。 载体中的氧化铝物质最有可能用作化学“锚”以控制钴物质的分散体，使得平均钴微晶尺寸可以大于平均孔径。

Abstract: Methods for preparing integral synthesis gas conversion catalyst extrudates including an oxide of a Fischer-Tropsch (FT) metal component and a zeolite component are disclosed. The oxide of the FT metal component is precipitated from a solution into crystallites having a particle size between about 2 nm and about 30 nm. The oxide of the FT metal component is combined with a zeolite powder and a binder material, and the combination is extruded to form integral catalyst extrudates. The oxide of the FT metal component in the resulting catalyst is in the form of reduced crystallites located outside the zeolite channels. No appreciable ion exchange of FT metal occurs within the zeolite channels. The acid site density of the integral catalyst extrudate is at least about 80% of the zeolite acid site density.
