A process for selectively opening cyclic paraffins (naphthenic rings) with substantially no subsequent cracking of the acyclic product has been developed. The process comprises contacting a cyclic paraffin feedstream with a catalyst at ring opening conditions to produce an acyclic paraffin product. The catalyst comprises a Group VIII metal, such as platinum, a modifier component, such as niobium or ytterbium, a molecular sieve, such as UZM-16 and a refractory inorganic oxide such as alumina. The Group VIII metal and modifier component are preferably deposited on the refractory inorganic oxide.
