Patent number: 10646849Abstract: A process to prepare a carbon molecular sieve adsorbent composition comprises steps beginning with an activated carbon having specific effective micropore size. The activated carbon is impregnated with monomers or partially polymerized polymer, allowed to complete polymerization, and then carbonized such that the impregnant shrinks the micropores to another specific effective micropore size. Finally, the impregnated/polymerized/carbonized product is annealed at a temperature ranging from 1000° C. to 1500° C., which ultimately and predictably shrinks the micropores to a size ranging from 4.0 Angstroms to 4.3 Angstroms. The invention surprisingly enables fine tuning of the effective micropore size, as well as desirable selectivity, capacity and adsorption rates, to obtain highly desirable carbon molecular sieving capability particularly suited for use in, for example, fixed beds in pressure swing or temperature swing processes to enable propylene/propane separations.Type: GrantFiled: September 8, 2016Date of Patent: May 12, 2020Assignee: Dow Global Technologies LLCInventors: Junqiang Liu, Chan Han, Janet M.

Patent number: 10646864Abstract: The purpose of the present invention is to provide a detection method which can safely recover a remaining sample from a detection device without causing a biological disaster. In order to achieve at least one of these goals, this detection method involves: a sample collection step for collecting a sample from the sample holding well, and transferring the same to a detection chip; a detection step for detecting the detected substance captured in the detection chip by means of a detection unit; and, after the sample collection step, a remaining sample recovery step for collecting the sample remaining in the sample holding well and transferring this to a sample recovery well. At that time, after the remaining sample recovery step, the surface area of the opening in the sample recovery well is smaller than the surface area of the opening in the sample holding well.Type: GrantFiled: January 29, 2016Date of Patent: May 12, 2020Assignee: Konica Minolta, Inc.Inventors: Youichi Aoki, Masataka Matsuo, Tetsuya Noda
