Zeolites as the modern catalysts for the high octane gasoline component production

Processes of isobutane with butenes alkylation with the purpose of obtaining the high octane gasoline component (alkylate), being environmentally detrimental due to use of concentrated H2SO4 or HF acids as catalysts, are nevertheless of great industrial importance supplying the world market with approximately 80 mln tons of alkylate yearly. The perspective of zeolite catalysts as the substitutes of the above concentrated acids in the modern alkylation process has been considered. The most effective today's solid alkylation catalyst of the narrow acid spectrum has been found. Such acidity spectrum is considered to be responsible for the essential prolongation of the effective catalyst lifetime.
