Selective conversion from cyclohexene to methylcyclopentene can occur via skeletal isomerization reaction under mild temperature and near atmospheric pressure with the existence of a catalyst structure as described herein. The catalyst structure includes a porous zeolite as the support and one or more loaded metals to further modify its acidity and pore structures. Industrially available cyclohexene feedstock can be effectively converted to a high value-added product methylcyclopentene with over 90 wt % conversion and 95 wt % selectivity, which is highly profitable for potential application in the fine chemical industry.

A method for converting cedarwood oil into high density fuels including, hydrogenating cedarwood oil in the presence of at least one hydrogenation catalyst to generate hydrogenated cedarwood oil, removing the hydrogenation catalyst from the hydrogenated cedarwood oil, purifying the hydrogenated cedarwood oil to produce a first high density fuel, isomerizing the first high density fuel in the presence of at least one acid catalyst catalyst to generate a hydrocarbon mixture including adamantanes, and distilling the adamantane mixture to produce a second alkyl-adamantane high density fuel.

The present invention relates to a chemical conversion process, preferably an isomerization process, for at least one hydrocarbon in the presence of an ionic liquid. The chemical conversion is performed in a dispersion, with dispersion of the hydrocarbon (phase (B)) in the ionic liquid (phase (A)) in the dispersion, the volume ratio of phase (A) to phase (B) being in the range from 2.5 to 4:1 [vol/vol].

A process for making high density fuels having the potential to increase the range and/or loiter time of Navy platforms. Derivation of these fuels from a sustainable source will decrease the carbon footprint of the Department of Defense (DoD) and reduce reliance on nonsustainable petroleum sources. Fuels based on ziza-anes have volumetric net heats of combustion up to ca. 18% higher than conventional Navy jet fuel (JP-5). Moreover, ziza-anes can be generated from sustainable biomass sugars via fermentation.
