Patent number: 6974496Abstract: The present invention provides compact adsorption systems that are capable of rapid temperature swings and rapid cycling. Novel methods of thermal swing adsorption and thermally-enhanced pressure swing adsorption are also described. In some aspects of the invention, a gas is passed through the adsorbent thus allowing heat exchangers to be very close to all portions of the adsorbent and utilize less space. In another aspect, the adsorption media is selectively heated, thus reducing energy costs. Methods and systems for gas adsorption/desorption having improved energy efficiency with capability of short cycle times are also described. Advantages of the invention include the ability to use (typically) 30-100 times less adsorbent compared to conventional systems.Type: GrantFiled: June 30, 2003Date of Patent: December 13, 2005Assignee: Battelle Memorial InstituteInventors: Robert S. Wegeng, Scot D. Rassat, Victoria S. Stenkamp, Ward E. TeGrotenhuis, Dean W. Matson, M. Kevin Drost, Vilayanur V. Viswanathan

Patent number: 6313393Abstract: A heat transfer and electric-power-generating component is disclosed that utilizes microstructural architecture for enhanced heat transfer. The component includes a heat source, a microstructural heat sink; and a thermoelectric device disposed between the heat source and the microstructural heat sink. During operation, heat flows from the heat source to the heat sink through the thermoelectric device such that the thermoelectric device can convert a portion of the heat flow into electric power. In some of the preferred aspects of the invention, the heat sink is an ultra thin film desorber combustor, and the heat source is a microchannel combustor. The microstructural architecture can provide high rates of thermal transfer through the thermoelectric device, allowing for surprisingly high thermoelectric power generation from a compact and light weight component.Type: GrantFiled: October 21, 1999Date of Patent: November 6, 2001Assignee: Battelle Memorial InstituteInventor: M.

Patent number: 4394859Abstract: An improved tower-mounted central solar energy receiver for heating air drawn through the receiver by an induced draft fan. A number of vertically oriented, energy absorbing, fin-shaped slats are radially arranged in a number of concentric cylindrical arrays on top of the tower coaxially surrounding a pipe having air holes through which the fan draws air which is heated by the slats which receive the solar radiation from a heliostat field. A number of vertically oriented and wedge-shaped columns are radially arranged in a number of concentric cylindrical clusters surrounding the slat arrays. The columns have two mirror-reflecting sides to reflect radiation into the slat arrays and one energy absorbing side to reduce reradiation and reflection from the slat arrays.Type: GrantFiled: October 27, 1981Date of Patent: July 26, 1983Assignee: The United States of America as represented by the United States Department of EnergyInventor: M.
