In this paper, we have shown modification of
high-silicon zeolite ZSM-5 by zirconium, and the results
of ethanol conversion on this catalyst. Effect of process
parameters on the selectivity of ethanol dehydration
products was analyzed. In addition, a mechanism of
aromatic hydrocarbons formation including reactions
of dehydrogenation, dehydrocyclization and alkylation
of intermediates was discussed. It was found that with
increasing temperature a selectivity decreased for reactions
of isomerization and increased selectivity for aromatic
products and products of cracking reactions. The data also
confirms that hexene-1 is an intermediate in the conversion
process of ethanol and the catalyst system with 1% Zr-ZSM-5
has a bi-functionality. Catalytic properties of the system
in the conversion of hydrocarbons are determined by the
presence on their surface of both Broensted and Lewis acid
sites.
