Abstract
Pseudoadiabatic axial temperature profiles may be observed, within windows of appropriate operating conditions, in fixed-bed catalytic reactors cooled A pilot-plant scale experimental facility was specifically designed and systematically used to carry out the reaction of conversion of methanol to gaso The data collected were used to confirm that the pseudoadiabatic operation is a useful condition for fixed bed reactors and to implement the reactor si Optimized kinetic and heat-transfer parameters were then employed with a two-dimensional pseudohomogeneous model to recalculate axial and radial temper Agreement between the simulation results and the experimental cross-sectionally averaged temperature profiles was very good within the pseudoadiabatic The hydrocarbon product distribution and the reactor throughput under pseudoadiabatic operation were comparable, or in some cases, even superior to pre
