Abstract
The present invention concerns, in the dehydroisomerization of at least one C.sub.4 -C.sub.5 n-paraffin, preferably n-butane, the use of a catalyst comprising a refractory oxide based support, preferably an alumina, at least one precious metal from group VIII, preferably platinum or palladium, optionally at least one element from group IVB such as titanium or zirconium, preferably titanium, optionally at least one element from the group formed by germanium, tin, lead, rhenium, tungsten and indium, and optionally at least one halogen such as chlorine. The present invention also concerns the regeneration of this catalyst.
