Organizations have invested and continue to invest considerable resources in Information and Communication Technology (ICT). Much of this investment is made on the basis of guarantee than an expected return will occur. This study presents the results of an empirical study of the impact of ICT investment on performance at the South African Post office (SAPO). Six years of historical data, from 2...

The dynamics of retained and deactivating species in a SAPO-18 catalyst during the methanol-to-olefins reaction have been followed using combination ex-situ in-situ techniques differential integral reactors.The were analyzed extraction, FTIR UV-vis spectroscopies combined with online product analysis (gas chromatography mass spectrometry). composition extracted soluble was determined gas chroma...

SSZ-13 materials have been synthesized with varying amounts of Al to produce samples with different concentrations of Brønsted acid sites, and consequently, these SSZ-13 materials contain increasing numbers of paired Al heteroatoms with increasing Al content. These materials were then characterized and tested as catalysts for the methanol-toolefins (MTO) reaction at 400 °C and 100% methanol con...
