| Abstract: | Alkylation of benzene with ethanol has been done in a
laboratory scale reactor with ZSM-5 diluted with silica as a catalyst. The
experiments have been done at the different reaction temperatures using
different catalysts in the reactor to study the change of activity and
selectivity of the desired product. The feed and products were analysed by gas
chromatography. Alkylation of benzene with ethanol yielded ethylbenzene as the
primary product and small amount of diethylbenzene isomers. For unmodified
H-type of ZSM-5 catalyst, higher conversion of benzene and the selectivity for
ethylbenzene go through a maximum between 400 and 450 ºC with a SiO2/Al2O3 ratio of around 100. The
SiO2/Al2O3
ratios were varied between 34 and 331. Modified B- and Mg- types of ZSM-5
zeolites are also examined. |
