Jul 29, 2009

Appl. No.:

12/511796

Inventors:

Michael E. Wright - Ridgecrest CA, US
Benjamin G. Harvey - Ridgecrest CA, US
Roxanne L. Quintana - Ridgecrest CA, US

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

C07C 2/22

US Classification:

585523, 585 14, 585510, 585511, 585512, 585517, 585518, 585520, 585521, 585522

Abstract:

A renewable biofuel based on a highly efficient batch catalysis methodology for conversion of 1-butene to a new class of potential jet fuel blends. By tuning the catalyst and then using the dimer produced, the carbon use is about 95% or greater.

International Classification:

C10L 1/04
C10G 63/04

US Classification:

208 17, 208 66

Abstract:

An effective method for producing high density fuel candidates from pinenes is provided. MMT-K10 is an efficient catalyst for the reaction, although significant amounts of p-cymene and camphene produced as byproducts limit the overall yield to about 80%. Nafion is also an excellent catalyst for pinene dimerization and was capable of producing dimers in up to 90% yield. Pinene dimers synthesized with these heterogenous catalysts have a density and net heat of combustion comparable to JP-10. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.

Inventors:

Benjamin G. Harvey - Ridgecrest CA, US

International Classification:

C10L 1/16
C07C 2/00

US Classification:

585 14, 585502

Abstract:

A process for making diesel and turbine fuels including, providing an effective amount of branched olefins, adding active heterogeneous acid catalyst(s) to said branched olefins to produce a solvent-free mixture, heating said solvent-free mixture greater than about 100 C. for a desired amount of time depending on various conditions, to produce Cdimers/catalyst mixture, removing said catalysts from said dimers/catalyst mixture, and adding hydrogenation catalyst(s) to said dimers under hydrogen atmosphere to produce a mixture of stable fuels.

International Classification:

C07C 2/08

US Classification:

585 16, 585255

Abstract:

A renewable biofuel based on a highly efficient batch catalysis methodology for conversion of 1-butene to a new class of potential jet fuel blends. By tuning the catalyst and then using the dimer produced, the carbon use is about 95% or greater. This latter point will be particularly important in the future, where the source of raw materials (i.e., biomass/biofeedstock) is limited.
