Process For Performing Reactions In A Liquid-Solid Catalyst Slurry
US Patent:
5527473, Jun 18, 1996
Filed:
Jan 9, 1995
Appl. No.:
8/369898
Inventors:
Carl D. Ackerman - Gibsonia PA
International Classification:
B01D 1900, B01D 5700, C07C 104
US Classification:
210767
Abstract:
A process for performing reactions in a liquid-solid catalyst slurry where feed gases pass continuously upward through the slurry bed contained in a reactor vessel and operating at elevated temperature and pressure; convening the gases to liquid and vaporous products; withdrawing the liquid products through a shaped-wire filter element having precise slit openings in the range between 0. 5 and 100 microns; and exiting from the bed and then from the top of the reactor vaporous products formed in the slurry and any unreacted gas. The filter element retains in the bed the solid catalyst particles larger than the slit width. The liquid is withdrawn to an accumulator external to the reactor vessel. The accumulator and the liquid chamber inside the filter element have unrestricted venting to the space above the expanded slurry bed. Liquid is withdrawn from the accumulator, while holding a suitable fixed level.
Wire Filter Element And Method Of Manufacture
US Patent:
5387340, Feb 7, 1995
Filed:
Jul 15, 1993
Appl. No.:
8/091284
Inventors:
Carl D. Ackerman - Gibsonia PA
International Classification:
B01D 2948, B01D 2954
US Classification:
21049701
Abstract:
A wire filter element having slit openings of between 0. 5 and 100 microns, and a method of manufacturing the filter element are disclosed. The filter element includes a plurality of generally parallel spaced elongated filter wire members having a trapezoidal cross-sectional shape, or rectangular cross-sectional shape separating pairs of trapezoidal shaped filter wires. Laterally extending support bars secure the filter wire in place. Ridges are formed on one side of the trapezoidal filter wires and on both sides of the rectangular filter wires. The ridges have lateral dimensions the same as the desired slit openings between adjacent filter wires. The filter wires are secured in place with the ridges engaging the upper side portions of adjacent filter wires. The ridges may be permanently fixed with the filter wires or removable after the filter wires are secured in place to define the slit openings.
