Expansion of pulse responses from temporal analysis of products (TAP) for more accurate data analysis

Abstract

TAP pulse responses are normally analysed using moments, which are integrals of the full TAP pulse response. However, in some cases the entire pulse response may not be recorded due to technical reasons, thereby compromising any data analysis due to moments generated from incomplete pulse responses. The current work discloses the development of a function which mathematically expands the tail of a TAP pulse response, so that the TAP data analysis can be accurately conducted. This newly developed analysis method has been applied to the oxidative dehydrogenation of ethane over Co–Cr–Sn–WO_x/α-Al₂O₃ and Co–Cr–Sn–WO_x/α-Al₂O₃ catalysts as a case study.
