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 comprises a Group (10) metal, and, optionally, a Group (11) metal, on a catalyst support with a Group (1) alkali metal silicate and/or a Group (2) alkaline earth metal silicate.

Methods and systems for recovering dicyclopentadiene from pygas are provided. Methods can include heating pygas to generated heated pygas, recovering a C 5 fraction from the heated pygas, and dimerizing cyclopentadiene from the C 5 fraction to form dicyclopentadiene. Methods can further include recovering the C 5 fraction from the pygas in a depentanizer column. Other methods can include heating pygas including dicyclopentadiene to form cyclopentadiene and hydrogenating cyclopentadiene in the pygas to form cyclopentane.
