摘要：

A mechanism has been found that explains the distribution of products obtained in the isomerizations of long‐chain alkanes on ZSM‐22 and SAPO‐11 catalysts so well that it should now be possible to tailor reactions for the synthesis of branched hydrocarbons. The reactions occur at the external surface of the catalyst according to a lock‐and‐key model (shown on the right); thus, the classical concept of shape‐selective catalysis within micropores is substantially extended.
