Process for conversion of acyclic C5 compounds to cyclic C5 compounds and formulated catalyst compositions used therein

A process for producing cyclopentadiene, the process comprising a step of contacting an acyclic C5 feedstock with a formulated catalyst composition under acyclic C5 conversion conditions effective to convert at least part of the acyclic C5 feedstock to produce an effluent comprising cyclopentadiene, wherein the acyclic C5 feedstock comprises acyclic C5 hydrocarbons and optionally hydrogen, a light hydrocarbon or a mixture thereof, and the formulated catalyst composition consists of:

• (i)a microporous crystalline metallosilicate;
• (ii) a metal of Group 10 of the Periodic Table or a compound thereof, and optionally, a metal selected from the group consisting of rare earth metals, metals of Groups 8, 9, or 11 of the Periodic Table, mixtures or combinations thereof, or a compound thereof, and
• (iii) a binder selected from the group consisting of one or more of silica, titania, zirconia, metal silicates of Group 1, Group 2, or Group 13 of the Periodic Table or mixtures thereof,
• and additionally
• (iv) an alkali metal of Group 1 of the Periodic Table, or a compound thereof;
• and/or
• (v) an alkaline earth metal of Group 2 of the Periodic Table or a compound thereof, wherein the formulated catalyst composition is made into one or more of an extrudate, a spray dried particle, an oil drop particle, or a spherical particle, followed by impregnating the extrudate and/or particle with the Group 10 metal, and/or the optional Groups 8, 9, or 11 metals.
