OLIGOMERS OF CYCLOPENTADIENE AND PROCESS FOR MAKING THEM

摘要

The invention provides a two-step process for converting cyclopentadiene dimer to a high density fuel mixture comprising the steps of: a) reacting the cyclopentadiene dimer in the presence of a solid catalyst comprising a porous crystalline material having a Constraint Index of from about 0.1 to about 12 under oligomerization/isomerization conditions to convert at least a portion of the cyclopentadiene dimer to a normally liquid intermediate product containing cyclopentadiene trimer, cyclopentadiene tetramer, and the isomerized and oligomerized products derived from the reaction of at least three cyclopentadiene monomer units; and b) hydrogenating the normally liquid intermediate product of step a) in the presence of a hydrogenation catalyst to form a normally liquid high energy density fuel.
