| 英文摘要 | the transesterification of soybean oil with methanol to biodiesel using lanthanum doped zinc aluminate with spinel structure as catalyst is studied. the catalyst was characterized by x-ray diffraction (xrd), n-2 adsorption/desorption, temperature programmed desorption of co2 (co2-tpd) and infrared spectroscopy of co2 adsorption (co2-ir). the results of co2-ir show that the basic sites of la doped zinc aluminate are surface isolated o2- anions and oh- groups. the results of co2-tpd show that the total amount of basic sties of the catalyst improves with the increase of the la doping amount until which is to 18.5 wt%. doping la also enlarges the pore volume and diameter of zinc aluminate. it gets the largest pore volume (0.30 cm(3) g(-1)) and pore diameter (7.9 nm) when doped with 5.5 wt% la. zinc aluminate doped with 5.5 wt% la (5.5% la/znal2o4) exhibits the highest activity, with which the biodiesel yield exceeds 95% at 160 degrees c, 2.0 mpa and 0.9h(-1). furthermore, the transesterification reaction of about 500h in a fixed-bed reactor was carried out over 5.5% la/znal2o4 catalyst. no deactivation and leaching of catalyst components were happened on the catalyst in reaction.
