Theory of the technology

A TCG berendezésekor követett alapelvek

It incorporates several new technological developments and design features such as:
modular construction and shop fabrication;
no requirement for refractory brick;
no requirement for separation and injection of oxygen;
no sensitivity to moisture content in the feedstock;
no requirement for pulverization or slurry injection of feed;
flexibility in feedstock alternatives including varying proportions of coal, pet coke, biomass, sewer sludge or other organic waste in different proportions;
utilization of a unique ionized water treatment system;
capability of recycling un-reacted carbons back into the reactor chamber, and a near-zero air emissions and liquid discharge.

In addition, some of the carbon dioxide generated in the gasification process can be captured and recycled as feedstock. Further the potential exists to readily integrate this system into a portable, flexible gas-to-liquids bio-refinery. There is substantial commercial potential in the TCG unit.

During the last years, many novel design aspects have been further developed that culminated in a US patent filed on April 11, 2006, application No: 60 / 791,401.

The „TCG-UC System” covers the whole problem area, offering the total solution from the grinding machine, via the TCG Unit, to the „SECU” - SynGas-Electricity energy Conversion Unit (Gas motors or Turbines,) - to the „LFU” - Liquid Fuel Unit (Fischer-Tropsh or Diesel Liquefaction) with a specific readyly available additional equipments.

A solid carbonaceous material synthesis (100 million BTU/h) gas generation plant (gasifier) was built on a test site. This commercial scale reference plant was completed in mid-August 2007. Currently conducting operational start-up activities at the University of Toledo, Ohio. The plant is designed to utilize carbonaceous feedstock from coal to biomass including wood chips, rice straw, ethanol plant DDGS, and municipal and industry waste products (i.e. organic sludge, industry waste, petroleum coke) for synthesis gas production. The plant feed system is designed to handle blended feedstocks, including coal mixed in any proportion, with the above mentioned materials.

The unique capability of the plant for utilizing a mixed fuel of coal and biomass in any proportion may provide synthesis gas composition from H2:CO=1:1 to H2:CO=1:3 which is most desirable for production of synthesis fuel, such as ethanol, mixed alcohols, diesel, gasoline, and jet-fuel.

The quantity of the components of SynGas depending on the pressure and temperature in the pyrolysis chamber and the time length while that the feed materilal is staying in it.
