  • Patent number: 10087121
    Abstract: A process to efficiently convert organic feedstock material into liquid non-oxygenated hydrocarbons in the C5 to C12 carbon skeleton range is disclosed. The process can utilize gaseous, liquid or solid organic feedstocks containing carbon, hydrogen and, optionally, oxygen. The feedstock may require preparation of the organic feedstock for the process and is converted first into a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is then cleaned and conditioned and extraneous components removed, leaving substantially only the carbon monoxide and hydrogen. It is then converted via a series of chemical reactions into the desired liquid hydrocarbons. The hydrocarbons are suitable for combustion in a vehicle engine and may be regarded a replacement for petrol made from fossil fuels in the C5 to C12 carbon backbone range.

  • Patent number: 9637433
    Abstract: A mobile system and method that reform flare gas, methane, or natural gas, using air without steam, to directly produce methanol, a clean burning gasoline blend, component, and/or substitute are disclosed. The system first reforms the air-methane mixture at ambient atmospheric pressure, then compresses the resulting CO-hydrogen-nitrogen gas mixture to 600 psi, and feeds it through a methanol reactor which reacts the gas mixture directly into methanol. The nitrogen is returned by the system back to the atmosphere. Methanol is a clean burning gasoline substitute, and can be used to displace significantly costlier and dirtier petroleum-based fuel, while solving a critical problem with flaring. For example, the over 120 billion cubic feet per year that was flared in North Dakota in 2014 could be converted into over 6 million tons of methanol.

  • Patent number: 9290422
    Abstract: A hybrid plant and method for producing liquid fuel product from hydrogen and carbon monoxide containing streams produced by gasifying solid carbonaceous feedstock and steam reforming of light fossil fuels. When a gasification unit in the hybrid plant is operating at reduced capacity or is not operational, oxygen that would have been used in the gasification unit is diverted to a light fossil fuel conversion unit containing an autothermal reformer to increase H2-rich syngas flow to a liquid fuel production unit and maintain liquid fuel production at near nameplate capacity.

  • Patent number: 9278891
    Abstract: A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production.

  • Patent number: 9242866
    Abstract: An activated carbon manufacturing system can efficiently heat a wood material or carbide to promote a drying process, a carbonization process and an activation process in manufacturing activated carbon, and can reduce the environmental load involved in the manufacture of activated carbon. Specifically, a drying process of a wood material is achieved by heating the wood material with saturated steam at an appropriate temperature, and an initial carbonization process of the wood material is achieved by heating the wood material with superheated steam. Therefore, the wood material can be heated with high heat transfer efficiency, so that the heat loss can be reduced, and neither a drying device nor a first carbonizing device produces a gas containing a harmful constituent in the heating processes, so that the adverse effect on the environment can be reduced.
