説明
To obtain basic data for methanol onboard reformer design, a kinetic study for the decomposition of methanol over Raney nickel alloy catalyst was carried out in a flow reactor at atmospheric pressure. The initial methanol decomposition rate, ri at a methanol partial pressure, PMeOH, in the range of 2070kPa, was<BR>ri= αPMeOH/ (1+βPMeOH) 2<BR>where α and β are constants.<BR>It was suggested that methanol adsorbed on the catalyst in an undissociative mode. The rate expression for methanol decomposition was assumed on the basis of the postulated mechanism, which involves the undissociative adsorption of methanol as the first step and hydrogen withdrawal from adsorbed methoxy radical as the rate-determining step.<BR>Kinetic analysis was performed for the reaction data obtained in the temperature range of 556628K by using integral reactor. The results calculated by the assumed rate expression agreed well with the experimental data. For the dehydration of methanol, occurring in parallel with the decomposition, the rate was found to be of first order with respect to the partial pressure of methanol.
