摘要：

Isomerization of n-butane over bifunctional Pd-impregnated catalyst pellets consisting of molecular sieve SAPO-31 or SAPO-11 and a silica binder has been investigated. Pd/SAPO-31 converts n-butane to iso-butane at temperatures of 700-725 K with good selectivities (more than 70% at conversion levels of 35-40%). The high activity is attributed to the outstanding properties of medium pore SAPOs for catalyzing the skeletal isomerization of intermediate butenes, which is considered to be the critical step in the reaction sequence.
