Process for preparing acetic acid by gas-phase oxidation of saturated C4-hydrocarbons and their mixtures with unsaturated C4-hydrocarbons

摘要

Shell catalyst for the production of acetic acid by gas phase oxidation of saturated and/or unsaturated 4 carbon (C) hydrocarbons consists of an inert, non-porous support and an outer coating of catalytically active mixed oxide comprising: (a) titanium dioxide (TiO2), zirconium dioxide (ZrO2), tin dioxide (SnO2) and/or aluminum oxide (Al2O3); and (b) 0.1-1.5 wt. % vanadium pentoxide (V2O5) with respect to (a) and per m2/g specific surface area of (a). An Independent claim is also included for the production of acetic acid using this catalyst.
