Publication number: 20240132425Abstract: Catalytic compositions and processes for depolymerizing polyolefin-based feed into useful petrochemical products are described. The compositions are a composite of a zeolite catalyst component and a co-catalyst comprising an activated clay component and/or a solid base component. These catalyst systems, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of impurities that may be present in the polyolefin-based feed. This results in a shorter residence time in the depolymerization unit and more efficient process.Type: ApplicationFiled: October 23, 2023Publication date: April 25, 2024Applicant: Basell Poliolefine Italia S.r.l.Inventors: Sandor Nagy, Christopher D.

Patent number: 6400128Abstract: A system and method for locating a circuit defect, such as a short or an incipient open, in an electric circuit in a workpiece, such a Printed Circuit Board (PCB) or MultiChip Module (MCM). The circuit is connected to a device for sensitively measuring any resistance change. A thermal stimulus is applied to various subsets of the surface of the workpiece, the thermal stimulus being temporally modulated, and the resistance change measurement correlated with this modulation. By applying well-designed thermal stimulus subsets, resistance measurements may be logically combined which correspond to the plural thermal stimulus subsets. Further, the search region where the defect may be located may be iteratively refined. By measuring the time delay between the thermal stimulus and corresponding resistance change, the depth of a defect below the surface of the workpiece is further determined.Type: GrantFiled: March 19, 2001Date of Patent: June 4, 2002Assignee: International Business Machines CorporationInventors: Daniel Guidotti, Arnold Halperin, Michael E.
