Tested of catalytic activity zeolites zsm-5 and beta in skeletal isomerisation reaction of n-butene to isobutene. Methods of temperature-programmed desorption of ammonia, low-temperature nitrogen adsorption investigated the variation of acid and textural characteristics of the studied samples. It is established that, depending on the concentration of acid sites zeolites exposed or substantial coking or intensively catalyzed cracking hydrocarbon products. A crucial role in increasing the yield of isobutene, presumably, plays the growing influence of steric factor in the accumulation of coke.
