| Abstract: | Alkylation of benzene with propene on a series of Beta zeolites under gaseous, liquid, vapor-liquid coexistence and supercritical conditions has been investigated. The highest yield of cumene and stability of the catalysts were observed when the reaction was carried out on Ga-modified H-Beta under supercritical conditions near the critical point, which may be ascribed to the effective dissolution and diffusion of the coke precursors deposited on the zeolites. |
