Transition metal phosphide hydroprocessing catalysts: A review
Abstract. The diminishing quality of oil feedstocks coupled with increasingly more stringent environmental regulations limiting the content of sulfur in transportation fuels have given rise to a need for improved hydroprocessing technology. This review begins with a summary of the major improvements in hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) catalysts and processes that ha…

A general method for determining the role of spectroscopically observed speci…
Abstract. A kinetic method is described to determine the role of adsorbed intermediates in heterogeneous reaction mechanisms. The method, denoted as analysis of coverage transients (ACT), involves comparing the time response of a spectroscopically observed species in an inert gas and a reactive gas to differentiate between adsorption–desorption processes and reaction. The method is applie…

Mechanistic study of propane selective oxidation with H2 and O2 on Au/TS-1
Abstract. The selective oxidation of propane to acetone and 2-propanol with H2 and O2 was studied on Au/TS-1 by kinetic and spectroscopic analysis. A kinetic study using a factorial design at conditions where the catalyst was stable and gave propane conversions of 90%, resulted in a power-rate law expression of the form roxyg. = koxyg.(H2)0.74(O2)0.36(C3H8)0.29. In situ Au L3-edge X-ray ab…

Epoxidation of propylene with H2 and O2 in the explosive regime in a packed-b…
Abstract. The vapor-phase epoxidation of propylene with H2 and O2 over a highly dispersed Au/TS-1 catalyst was carried out in a packed-bed catalytic membrane reactor. The membrane reactor allowed the use of high concentrations of H2 and O2 (40% each) that were well within the explosive regime, and the production rate of propylene oxide was improved by 100–200% compared with that from a co…
