    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 said 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 said 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;(b) hydrogenating said normally liquid intermediate product of step (a) in the presence of a hydrogenation catalyst to form a normally liquid high energy density fuel.

    摘要： A method for producing substantially linear hydrocarbons by oligomerizing a lower olefin at elevated temperature and pressure which comprises contacting the lower olefin under oligomerization/polymerization conditions with constrained intermediate pore siliceous acidic zeolite, e.g., ZSM-22, -23 or -35, having Bronsted acid activity; wherein the zeolite has acidic pore activity and wherein the zeolite surface is rendered substantially inactive for acidic reactions. The zeolite surface can be inactivated by contact with dicarboxylic acid, e.g., oxalic acid. The olefin oligomers may be used as alkylating agents to prepare biodegradable alkylbenzenes and alkylphenylsulfonates.
