Abstract:
Processes for catalytically synthesizing ethylbenzene from ethanol and benzene comprises (1) reacting a first mixt. comprising ethanol and benzene with at least one catalyst chosen from binder-contg. alkylation catalysts and binder-free alkylation catalysts in an alkylation reactor to form a second mixt. comprising residual benzene, ethylbenzene, diethylbenzene, and water; (2) passing the second mixt. successively through a benzene recovery tower, an ethylbenzene recovery tower, and a polyethylbenzene recovery tower to give sepd. water, sepd. benzene, sepd. ethylbenzene, and sepd. diethylbenzene; and (3) reacting a third mixt. with at least one transalkylation catalyst in a transalkylation reactor, wherein the third mixt. comprises at least some of the sepd. benzene and at least some of the sepd. diethylbenzene at ratio 2:1-10:1.
