| 英文摘要 | solid bases were prepared by calcining as-prepared zn-al hydrotalcites at different temperatures. the evolutions of their structure and basicity were characterised using x-ray diffraction, thermogravimetric analysis, infrared spectroscopy of co2 adsorption and temperature programmed desorption of methanol. with an increase in the calcination temperature, the as-prepared zn-al hydrotalcites were firstly converted into dehydrated zn-al hydrotalcites and next converted into zn-al oxides. the basic sites of these solid bases changed from oh groups to mn+- o2- (m = zn or al) pairs and isolated o2- ions. these solid bases were evaluated in transesterification reactions used for biodiesel production. the dehydrated zn-al hydrotalcites obtained at 473 k exhibit the highest activity, with a biodiesel yield of approximately 76% at 413 k, 1.7 mpa and 1.0 h(-1). this catalyst exhibits no deactivation after about 150 h. the structure-reactivity relationship of the catalyst is also discussed. |
