Granted: 2011-10-25
Abstract: A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device uses a self-calibrated magnetic binding assay format (e.g., sandwich, competitive, etc.) that includes detection probes capable of generating a detection signal (e.g., fluorescent non-magnetic particles) and calibration probes capable of generating a calibration signal (e.g., fluorescent magnetic particles). The amount of the analyte within the test sample is proportional (e.g., directly or inversely) to the intensity of the detection signal calibrated by the intensity of the calibration signal. It has been discovered that the fluidics-based device of the present invention provides an accurate, inexpensive, and readily controllable method of determining the presence of an analyte in a test sample.

Title: Process for the selective hydrogenation of alkynes
Inventor: RYU YONG J
IPC: C07C7/167
Filed: 2003-10-29
Granted: 2009-09-29
Abstract: An improved selective hydrogenation process for removing acetylenic impurities such as vinyl acetylene, ethyl acetylene, propyl acetylene and acetylene in a steam cracked crude butadiene stream by selective hydrogenation is carried out in two steps. In the first step, the partial selective hydrogenation is carried out in a fixed bed with a copper based catalyst (12) to have the ratio of vinyl acetylene to ethyl acetylene in a range of from 0 to about 1 , preferably from about 0.01 to 0.6, in the product stream. In the second step, the selective hydrogenation of the remaining C4 acetylenic impurities is carried out to completion in the catalytic distillation mode using a palladium promoted copper catalyst (24, 26, 28, and 30), an improved palladium catalyst or a combination of these two. The product stream (14) from the first step partial hydrogenation is introduced to the catalytic distillation column (20) at a position within the catalytic reaction zone and hydrogen feed gas (18) is introduced below the catalyst bed to maximize the recovery of 1 ,3-butadiene.  The feed positions (22a, 22b, and 22c) to the catalytic distillation column may vary along the catalyst loading zone depending on the feed composition from the first step selective hydrogenation reactor. Optionally, to prolong the catalyst service and cycle time, a solvent is added to the reactor with the hydrocarbon bed stream in the first step or the second step or both steps
