WebAll the preliminary measurements of the Rh-3/5/Si02 (denoted as Rh-3-SILP) catalyst discussed so far were initially studied at 100 °C and 10 bar syngas pressure (H2 CO 1 1) over a period of up to 36 h. This time on stream was further extended to 180 hours to test the long-term stabihty of the Rh-3-SILP dehydroxylated catalyst system (Fig. 3).

WebAbstract: Water-soluble rhodium-phoshpine complex HRhCO(TPPTS) 3 and TPPTS were supported by hydroxyapatite(HAP). The catalysts were characterized by FTIR, solid state 31 P CP-MAS NMR, SEM, ICP-OES, and N 2 adsorption-desorption measurements. The catalysts showed special isomerization performance for 1-hexene, 2-hexene and 3-hexene.
