Abstract
The invention relates to nano zirconium hydroxide, a preparation method thereof and an n-butane skeletal isomerization catalysis method using the nano zirconium hydroxide. The nano zirconium hydroxide has a spherical and / or sphere-like morphology, and the particle size distribution is 10-30nm. The nano zirconium hydroxide is especially suitable for being used as a catalyst carrier, is especially suitable for being used as a carrier of an n-butane isomerization catalyst, and can improve the conversion per pass of n-butane and the selectivity of isobutane.
