摘要

Ethylene and 1,3-butadiene are important organic chemical raw materials.Petroleum hydrocarbon cracking is the most widely used method for ethylene fabrication worldwide.In this study,the use of a ZrO_(2) catalyst,which can be easily synthesized,for the efficient conversion of bioethanol to ethylene and 1,3-butadiene was analyzed.X-ray diffraction,transmission electron microscopy,temperature-programmed desorption,and Fouriertransform infrared spectroscopy analyses were used to evaluate the surface properties of ZrO_(2).The selectivity of ZrO_(2) toward ethylene and 1,3-butadiene was as high as 98.2%.Catalyst selectivity toward dehydration or dehydrogenation products depends on the nature of the weak acid-base catalytic sites,whereas high-strength base and intermediate-strength acid catalytic sites selectively yield ethylene.
