Dehydrocyclization of hexane to benzene over zirconia-supported chromia
Abstract
A dehydrogenation catalyst for alkanes was obtained by exposing Zr(OH)4 to 0.05M-(NH4)2CrO4, followed by calcination in air at 600–800 °C and reduction at 550 °C; this catalyst converted hexane into benzene with a selectivity of up to 84%.
