Ammonia Borane Complex Thermolysis-Borazine Capture Utilizing Solid Sorbents

Abstract

Thermolysis has been employed by many to generate hydrogen from ammonia borane (AB) complex. Even though, AB pyrolysis begins at temperatures below 140° C, to release all of the hydrogen contained in ammonia borane, temperatures in excess of 500° C are required. The overall process is exothermic, but requires heat to be added to activate the AB complex. One of the main drawbacks of AB thermolytic process is the involvement of competing reactions leading to the formation of certain undesirable by-products such as borazine and polymeric aminoboranes. Borazine introduction to PEM fuel cell as an impurity can limit the lifetime and performance of fuel cell's catalysts and electrodes. Hence, it is highly crucial to purify the H2 gas stream from borazine. In this paper, the borazine scrubbing capability and efficiency of different solid sorbents will be discussed.
