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 compostions disclosed herein and their reaction products will neither melt nor char at temperatures in excess of 100c . 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 .
