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： 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.
