Abstract
Abstract A shape-selective metal-containing catalyst composition comprises a porous crystalline silicate which has a Constraint Index between 1 and 12 and which contains boron in tetrahedral coordination in the crystal lattice of the silicate and a metal from Group VIII of the Periodic Table of Elements, the catalyst composition containing less than 0.1% by weight of elemental aluminum on an ash basis.
