Disclosed is a process for the conversion of acyclic C5 feedstock to a product comprising cyclic C5 compounds, including cyclopentadiene, and catalyst compositions for use in such process. The process comprises contacting the feedstock and, optionally, hydrogen under acyclic C5 conversion conditions in the presence of a catalyst composition to form said product. The catalyst composition comprises a microporous crystalline metallosilicate, a Group 10 metal or compound thereof, and a Group 11 metal or compound thereof.
