HYDROGEN SULFIDE POISONING OF METHANOL SYNTHESIS Cu-BASED CATALYST (III) EFFECTIVENESS FACTOR OF POISONED CATALYST

The single component model and the multicomponent model of the effectiveness factor ζ_d, of the poisoned catalyst have been proposed and solved by the orthogonal collocation method. The center equilibrium dead zone was founded in catalyst pellets. The calculated values ζ_d, were respectively 0·1229-0·2907,0·1298-0·2445 and 0·0690-0·2155 for No. 1, No. 2 and No. 3 catalyst. The average of the absolute values of the relative deviations between the experimental values and the calculated values by model for ζ_d was less than 11 per cent. The models can be used to calculate the effectiveness factor of the poisoned catalyst.
