The process is notably “non-Fischer-Tropsch” meaning that it does not require oxygen to be admitted into the reactor for supplying thermal energy by partial combustion, which is normally required to split methane. This freedom from high temperature operation and the other demands of an oxygenation process means that higher carbon efficiency is achievable This is made possible with mechanochemistry and “sonic catalysis” that employ kinetic energy to promote the breakdown of methane molecules, the reformation of the resulting carbon-hydrogen fragments, and the rejuvenation of the catalyst surface. A number of liquid fuels can be produced which are easily transported and fully marketable without further processing. Within the range of output products is a liquid solvent which can be used as a substitute “fracking” fluid, which is recoverable as recycled feedstock for further conversion—thus eliminating the problem of water treatment. The reactor can be made more compact, lighter, modular, skid-mounted and fully transportable to the well-head where the gas-to-liquid conversion process reduces the release of natural gas and enables the monetization of stranded or flared gas.09-18-2014

20140128654Reactor and Alkylation Process Using the Reactor - The present disclosure provides a reactor for at least two liquid materials, comprising an enclosed reactor housing; a feeding tube having liquid material inlets for receiving corresponding liquid materials respectively; a distribution tube communicating with the feeding tube and extending into the reactor housing, the distribution tube being provided with a plurality of distribution holes in the region thereof extending into the reactor housing; a rotating bed in form of a hollow cylinder, which is disposed in the reactor housing via a fixing mechanism, thus dividing inner cavity of the reactor housing into a central area and an outer area, the rotating bed being capable of rotating driven by a driving mechanism; and a material outlet provided in a lower portion of the reactor housing for outputting product after reaction. The distribution tube extends into the central area spaced from inner surface of the rotating bed, so that materials can enter into the outer area from the central area through the rotating bed and can be output via the material outlet.05-08-2014
