| 英文摘要 | one-step transformation of isobutyl alcohol to aromatics (benzene, toluene, and xylene) has been studied in a gas phase, fixed-bed reactor system over several purely acidic zeolites and zeolite-supported metal catalysts. zsm-5 zeolites give higher aromatics yields (similar to 42 wt %) among the evaluated zeolites, and the si! al ratios (si/al = 13-43) of zsm-5 slightly influence their catalytic performances. during the transformation of isobutyl alcohol, large amounts of short alkanes (mainly propane and butane isomers) are also generated on the acidic zsm-s. to improve the conversion to aromatics, several metal species (zn, ga, mo, la, ni, ag, and pt) are supported on the zsm-5. the enhancements in aromatics yields (similar to 60wt %) are observed only on the zn/zsm-5 catalysts. the incorporation of zn species preferentially decreases the strong-strength bronsted acidity and, thus, suppresses the cracking to c-3 fragments. moreover, mainly the zn species at the exchange sites facilitate the recombinative desorption of h-2 and, hence, enhance the reactions toward aromatics. through these effects, zn/zsm-5 catalysts exhibit the remarkably promoted formation of toluene and xylene and inhibit the generation of undesired alkanes products. |
