Appl. No.:

8/647093

Assignee:

Sandia Corporation - Alburquerque NM

International Classification:

C09K 300

US Classification:

25218212

Abstract:

A hydrogen getter composition comprising a double or triple bonded hydrocarbon with a high melting point useful for removing hydrogen gas, to partial pressures below 0. 01 torr, from enclosed spaces and particularly from vessels used for transporting or containing fluids at elevated temperatures. The hydrogen getter compositions disclosed herein and their reaction products will neither melt nor char at temperatures in excess of 100. degree. C. They possess significant advantages over conventional hydrogen getters, namely low risk of fire or explosion, no requirement for high temperature activation or operation, the ability to absorb hydrogen even in the presence of contaminants such as water, water vapor, common atmospheric gases and oil mists and are designed to be disposed within the confines of the apparatus. These getter materials can be mixed with binders, such as fluropolymers, which permit the getter material to be fabricated into useful shapes and/or impart desirable properties such as water repellency or impermeability to various gases.

Abstract:

A thermally insulating panel structure (2, 60) is created by filing the space (16, 67) between two panels (4, 6, 61, 62) with a gas exhibiting low thermal conductivity at a moderately low pressure so to substantially eliminate convection heat flow through the insulating region but not so low as to substantially reduce conduction heat flow through the insulating region. Doing so greatly increases the thermal insulating qualities of the structure without the problems associated with evacuating the region to extremely low pressures. The seal (14, 50, 66) at the edges (10, 12, 64, 65) of the panels can define one or more barrier regions (44, 46) which reduce air leakage into the insulating region.
