Abstract

A saturated hydrocarbon charge containing both butane and isobutane is subjected to selective hydrogenolysis in the presence of a catalyst comprising a specific carrier and 0.1 - 10 % b.w. of rhodium. Butane is thus selectively converted to ethane and propane, while isobutane is preserved or formed and can be recovered from the reaction product.
