Abstract 1. A METHOD FOR DEHYDROGENATING A DEHYDROGENATABLE HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF NORMAL PARAFFIN HYDROCARBONS CONTAINING 2 TO 30 CARBON ATOMS PER MOLECULE, ALKYLAROMATIC HYDROCARBONS WHERE THE ALKYL GROUP CONTAINS 2 TO 6 CARBON ATOMS, AND NAPHTHENES, COMPRISING CONTACTING THE HYDROCARBON, AT DEHYDROGENATION CONDITIONS, WITH A CATALYTIC COMPOSITE CONSISTING ESSENTIALLY OF A TIN COMPONENT IN COMBINATION WITH A PLATINUM COMPONENT ON A CARRIER MATERIAL AND PREPARED BY THE METHOD WHICH COMPRISES: (A) IMPREGNATING A HIGH SURFACE AREA, POROUS CARRIER MATERIAL WITH A SOLUTION OF COMPLEX CHLOROSTANNATE (II) CHLOROPLATINATE ANIONIC SPECIES, SAID SOLUTION BEING STABILIZED IN CONTACT WITH SAID CARRIER MATERIAL WITH AN AQUEOUS HALOGEN ACID; AND THEREAFTER, (B) DRYING AND CALCINING THE IMPREGNATED CARRIER MATERIAL.
