Abstract
Heteropolyacids (HPAs) supported on the activated carbon (SiW12/C and PW12/C) have been used to study the formation of methyl tert-butyl eth er (MTBE). Compared to the conventional commercial catalysts, Amberlys t-15 resin and HZSM-5, HPAs supported catalysts have been proved to ha ve much higher catalytic activity under lower temperature, especially selectivity to MTBE is up to 100%. It may be due to the high acid stre ngth of HPAs as well as the specialty of heteropolyanion.
