Disclosed is a process for the conversion of acyclic C 5 feedstock to a product comprising cyclic C 5 compounds, such as, for example, cyclopentadiene, and catalyst compositions for use in such process. The process comprises the steps of contacting said feedstock and, optionally, hydrogen under acyclic C 5 conversion conditions in the presence of a catalyst composition to form said product. The catalyst composition comprising a microporous crystalline aluminosilicate having a constraint index in the range of 3 to 12, a Group 10 metal, and, optionally, a Group 11 metal, in combination with a Group 1 alkali metal and/or a Group 2 alkaline earth metal. |
