    Abstract: Describe are preferred formulations for Avgas meeting the requirements for use in aircraft, including requirements established under ASTM standards and by the Federal Aviation Administration. In one embodiment, a binary mixture of 1,3,5-trimethyl benzene (mesitylene) and isopentane is used to provide a MON of at least 100, and more preferably at least 102. In other embodiments, the amounts of mesitylene and/or isopentane may be changed, and other fuel components are included. These various Avgas formulations are thereby adjusted to meet a variety of requirements as to octane rating, RVP, cold start, and other fuel characteristics.

    Abstract: A process for converting C2-5 alkanes to higher value C5-24 hydrocarbon fuels and blendstocks. The C2-5 alkanes are converted to olefins by thermal olefination, without the use of a dehydrogenation catalyst and without the use of steam. The product olefins are fed to an oligomerization reactor containing a zeolite catalyst to crack, oligomerize and cyclize the olens to the fuel products which are then recovered. Optionally, hydrogen and methane are removed from the product olefin stream prior to oligomerization. Further optionally, C2-5 alkanes are removed from the product olefin stream prior to oligomerization.

    Abstract: Described are preferred compositions for a motor fuel. Such motor fuels may be particularly well suited for use in the motor of an aircraft. In particular, compositions of the present disclosure may comprise alicyclic alkanes, straight or branched chain alkanes, and aromatics. In a preferred embodiment, the fuel comprises cyclopentane, isooctane, and one or more aromatics selected from xylene, toluene, and trimethylbenzenes. The present disclosure describes a full spectrum of unleaded fuels with various motor octane (MON) values to address a wide range of aviation fuel needs in the global marketplace.

    Abstract: Disclosed is a process for converting C2-5 alkanes to higher-value C5-24+ hydrocarbon fuels and fuel blendstocks including reacting the C2-5 alkanes in a thermal olefination reactor operating at a temperature, pressure and space velocity to convent the alkanes to olefins and in the absence of both a dehydrogenation catalyst and steam. At least a portion of the product olefin stream is oligomerized using a zeolite catalyst to crack, oligomerize and cyclize the product olefins to form the fuel products, which are then recovered. The process is useful in removing sulfur and nitrogen-based compounds in a single step process, while reducing total costs of processing and eliminating the need for additives used in the field.
