Abstract
A process for the isomerization of mono-olefins in aliphatic hydrocarbon streams is carried out at 40 to 300° F. under low hydrogen partial pressure in the range of about 0.1 psi to less than 70 psi at 0 to 350 psig in a distillation column reactor containing a hydrogenation catalyst which serves as a component of a distillation structure, such as supported PdO encased in tubular wire mesh. Essentially no hydrogenation of the mono-olefins occurs.
