Abstract
In order to determine the influence of pore geometry on reaction rate and selectivity in dehydration, the dehydration of ethanol and n-butanol to olefins and ethers over various zeolite catalysts was studied. The commercial zeolites, Linde-X, Linde-A, and Norton Zeolon in sodium form were base-exchanged with lithium, potassium, magnesium, calcium, barium and, in one case, hydrogen. Both reaction rate and selectivity were found to be strongly influenced by sieve type and by the size and charge of the exchanged cation. Selectivity between the formation of alcohol and ether was also strongly dependent on the length of the alcohol chain, and, for some sieves, on temperature.
