C. Thomas et al., Deuterium tracer studies on hydrotreating catalysts. 3. Influence of nickel on the rates of H-2-D-2 and H2S-D-2 isotopic exchange, CATAL LETT, 58(1), 1999, pp. 33-35
The H-D isotopic exchange between H-2 and D-2 and between H2S and D-2 was c
arried out at 80 degrees C in a recycling reactor over a series of presulfi
ded Mo/Al2O3 catalysts containing different amounts of nickel. Whatever the
pretreatment procedure, it was found that the promoter had no significant
effect on the rate of H-D exchange or on the amount of exchangeable hydroge
n present on the catalysts.
