Abstract:
The process of dehydration of ethanol to ethylene at varied dimensions of an alumina ring catalyst was studied using the mathematical 2D model of the tube reactor to determine the equivalent size R-eq of the catalyst grain that, in turn, determine the efficiency η of the internal surface of the catalyst. The method was suggested for assigning grains with different dimensions to four structure groups depending on the procedure for preparation of samples with identical
R-eq. The system of criteria for identification of catalyst grains with the best characteristics for the given conditions was developed based on the suggested approach. Grain dimensions and the other parameters providing the highest ethylene yield at the lowest pressure drop and shortest contact time were determined.
