Equilibration of Linear and Branched Alkanes with Deuterium

EQUILIBRATION OF LINEAR AND BRANCHED ALKANES WITH DEUTERIUM  

Most studies of the methane-deuterium reaction have been performed in static systems, which do not clearly reveal changes of activity with time in a flow-system, however, films of metals in Groups 5 and 6, and nickel, increase in activity with 

TABLE 6.1. Rates of Methane Exchange with Denterinm at 423 K and Apparent Arrhenius Parameters (E, In A) for Metals in Various Physical Forms 

The rates are those for methane removal and have been measured at various reactant pressures, so that tiiey and the apparent Arrhenius parameters on which they are based have no absolute significance. 

Activation energies are generally rounded to two or three significant figures, but rate may have been calculated from more accurate values.
