Methods for the production of renewable dimethyl JP10

摘要

A highly efficient method for the conversion of a natural product into the high density fuel RJ-4 with concomitant evolution of isobutylene for conversion to fuels and polymers, more specifically, embodiments of the invention relate to efficient methods for the conversion of the renewable, linear terpene alcohol, linalool into a drop-in, high density fuel suitable for ramjet or missile propulsion.

主权项

1. A method for manufacturing high density fuels, comprising:
reacting at least one terpene alcohol with at least one Ru-metathesis catalysts with a solvent or under solvent-free conditions to produce 1-methylcyclopent-2-enol and isobutylene; continuously separating said isobutylene by distillation; dehydrating said 1-methylcyclopent-2-enol with at least one heterogeneous dehydration catalyst to produce a mixture consisting of 2-methyl cyclopentadiene and 1-methyl cyclopentadiene; thermal dimerizing said methylcyclopentadienes to produce a mixture of methylcyclopentadiene dimers comprising greater than 50% 3,9-dimethyl-endo-tricyclo[5.2.1.02,6 ]deca-3,8-diene and about 30% 4,9-dimethyl-endo-tricyclo [5.2.1.02,6]deca-3,8-diene; hydrogenating said methylcyclopentadienes dimers with at least one hydrogenation catalyst to produce hydrogenated methylcyclopentadienes dimers; and isomerizing said hydrogenated methylcyclopentadienes dimers with at least one Lewis acid catalyst to produce high density fuels.
