Disclosed is a process for the conversion of acyclic Cfeedstock to a product comprising cyclic Ccompounds, such as for example, cyclopentadiene, and catalyst compositions for use in such process. The process comprising the steps of contacting said feedstock and, optionally, hydrogen under acyclic Cconversion conditions in the presence of a catalyst composition to form said product. The catalyst composition comprising a crystalline aluminosilicate having a constraint index of less than or equal to 5, and 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.

Disclosed is a process for the conversion of acyclic Cfeedstock to a product comprising cyclic Ccompounds, 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 Cconversion 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.

A process for converting paraffins, especially light paraffins, e.g. C-Cparaffins, to higher boiling range paraffinic liquid hydrocarbons comprises endothermically dehydrogenating the light paraffin combined with a thermally coupled, exothermic reaction such as olefin oligomerization to supply heat for the endothermic conversion.
