摘要

Very large differences can be observed in n-butene transformation at 623K over two H-ferrierite samples with Si/Al ratios of 10.2 (HFER10) and 18.8 (HFER19). At short TOS, the selectivity to isobutene is higher on HFER19 than on HFER10; with both zeolites, this selectivity increases with TOS, which can be related to an effect of coke deposit. The selectivity increase is more significant with HFER10 which becomes the most selective sample at long TOS. With HFER19, the yield in all the products decreases, the decrease being less significant for isobutene. In contrast, with HFER10, after a significant initial decrease, the isobutene yield increases with TOS becoming higher than on the fresh sample. Proposals are made to explain this large difference in the behaviour of the HFER samples.
