Supportive conversations conversation improvement considerations

Industrial application of the Au catalysts would be feasible if 10% conversion of propene could be achieved. However, there still remains a number of serious problems low PO 4elds (<2%), low selectivities at high reaction temperature, deactivation with time-on-stream and low H2 efficiency (<30%). The first two problems could be somewhat improved when titania-modified silica and titanosilicates were used as supports for Au nanoparticles. The initial conversion of propene was increased to ca. 5% from 2% or below, when the reaction temperature was raised to 423 K from 353 K or below without considerable loss in PO selectivity [40,402]. To date, only small improvements in the deactivation of Au catalysts with time-on-stream have been reported,...
