Publication number: 20150251335Abstract: Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.Type: ApplicationFiled: May 18, 2015Publication date: September 10, 2015Inventors: Thomas Richard Chapman, Jacob George, Ralph Henry Hagg, Amit Halder, Huthavahana Kuchibhotla Sarma

Publication number: 20150233636Abstract: Systems and methods for efficient microwave drying of extruded honeycomb structures are disclosed. The methods include conveying first and second sets of honeycomb structures in opposite directions through multiple applicator cavities. Each honeycomb structure has a moisture content MC, and the honeycomb structures within each cavity define an average moisture content MCA between 40% and 60% therein. The methods include irradiating the first and second sets of honeycomb structures within the cavities with microwave radiation having an amount of input microwave power PI that results in an amount of reflected microwave power PR from the honeycomb structures, where PR<(0.2)PI. This allows for a relatively high microwave power to be maintained in each cavity. Batch microwave drying methods are also disclosed.Type: ApplicationFiled: May 6, 2015Publication date: August 20, 2015Inventors: James Anthony Feldman, Jacob George, Amit Halder, Nadezhda Pavlovna Paramonova

Patent number: 9073000Abstract: A reactor for adsorbing CO2 from a fluid stream includes a reactor housing having a fluid inlet and a fluid outlet. The reactor also includes an inlet ceramic honeycomb structure and an outlet ceramic honeycomb structure positioned inside the reactor housing. The inlet and outlet ceramic honeycomb structures have a plurality of partition walls extending in an axial direction thereby forming a plurality of flow channels and comprises a material that forms bonds with CO2 to adsorb the CO2. The inlet ceramic honeycomb structure is capable of adsorbing an inlet quantity of CO2 and the outlet ceramic honeycomb structure is capable of adsorbing an outlet quantity of CO2. The inlet quantity of CO2 is greater than the outlet quantity of CO2.Type: GrantFiled: March 14, 2012Date of Patent: July 7, 2015Assignee: Corning IncorporatedInventors: Amit Halder, Steven Bolaji Ogunwumi

Patent number: 9011583Abstract: An article comprising a plurality of intersecting walls having outer surfaces that define a plurality of cells extending from one end to a second end, wherein the walls forming each cell in a first subset of cells are covered by a barrier layer to form a plurality of heat exchange flow channels, and wherein the walls forming each cell in a second subset of cells different from the first subset of cells, comprise a CO2 sorbent and form reaction flow channels. Heat exchange flow channels allow quick and uniform heating and cooling of the sorbent body. The article may be useful, for example, for removing CO2 from a gas stream.Type: GrantFiled: April 29, 2011Date of Patent: April 21, 2015Assignee: Corning IncorporatedInventors: Amit Halder, Dayue David Jiang, Weiguo Miao, Steven Bolaji Ogunwumi, Zhen Song

Publication number: 20140366725Abstract: High volumetric-efficiency thermally integrated systems for capturing a target gas from a process gas stream include a monolithic body and a distribution system. The monolithic body includes a first plurality of channels and a second plurality of channels each having sorbent surfaces that reversibly adsorb the target gas. The channels are in thermal communication such that heat from an exothermic adsorption of target gas in one plurality of channels is used by an endothermic desorption of target gas from the other plurality of channels. Methods for separating a target gas from a process gas stream include switching the high volumetric-efficiency thermally integrated systems between a first state and a second state. In the first state, the first plurality of channels undergoes desorption while the second undergoes adsorption. In the second state, the second plurality of channels undergoes desorption while the first plurality undergoes adsorption.Type: ApplicationFiled: September 3, 2014Publication date: December 18, 2014Inventors: Amit Halder, Steven Bolaji Ogunwumi

Publication number: 20140327186Abstract: Systems and methods for rapid drying of ceramic greenwares having a high graphite content are disclosed. The methods include employing microwave drying to bring the dryness of the ceramic greenware to a first select dryness and then employing close-coupled hot-air drying to bring the dryness to the final target dryness. The judicious use of close-coupled hot-air drying reduces end defects due to unevenness in the microwave drying process while also substantially speeding up the drying process. Various configurations for and combinations of microwave drying and close-coupled hot-air drying are disclosed.Type: ApplicationFiled: March 31, 2014Publication date: November 6, 2014Applicant: Corning IncorporatedInventors: Willard Ashton Cutler, James Anthony Feldman, Jacob George, Amit Halder, Nadezhda Pavlovna Paramonova, Todd Parrish St Clair
