Pore structure and acid properties of high-silica zeolites synthesized with different templates and their catalytic performance in conversion of the propane–butane fraction

Resumo

The effect of the template on the physicochemical properties of zeolitic catalysts and on the yield and selectivity of formation of aromatic hydrocarbons in conversion of the propane–butane fraction was examined. The zeolitic catalyst sample synthesized with an alcohol fraction as template is characterized by the highest values of the acid site concentration, adsorption capacity, micropore volume, and specific surface area. Therefore, this catalyst ensures the highest, compared to the other samples, conversion of the propane–butane fraction and yield of aromatic hydrocarbons.
