Process for Conversion of Acyclic C5 Compounds to Cyclic C5 Compounds and Catalyst Composition for Use Therein

摘要

Disclosed is a process for the conversion of acyclic C5 feedstock to a product comprising cyclic C5 compounds, 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 C5 conversion 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.

1. A process for conversion of an acyclic C5 feedstock to a product comprising cyclic C5 compounds including cyclopentadiene, said process comprising the steps of contacting said feedstock and, optionally, hydrogen under acyclic C5 conversion conditions in the presence of a catalyst composition to form said product, wherein said catalyst composition comprises a microporous crystalline aluminosilicate having a constraint index of less than or equal to 5, and a Group 10 metal in combination with a Group 1 alkali metal and/or a Group 2 alkaline earth metal and, optionally, a Group 11 metal.
