We can provide expertise in both "direct" and "indirect" thermal conversion methods. Recent advances in catalytic processing are expected to enable the economic conversion of refuse derived feeds into liquids that can be blended with gasoline and diesel fuels.
The "indirect" route uses catalyst technology to convert synthesis gases (syngas) into chemical intermediates, including methanol and dimethyl ether (DME), which are then converted into hydrocarbons used as "drop-in" transportation fuels.
The "direct" route generates liquids by catalytic cracking of cellulosic feeds, and results in the production of both aromatic liquids and fuel-gases.
Single and dual fluidized bed technologies are available.
"GTI’s gasification process is an excellent technology for many industrial applications requiring fuel-gas or synthesis gas to produce high-value liquids, or electric power. The inherent fuel flexibility of fluidized bed gasifiers permits the use of low-cost "opportunity feedstocks" including all ranks of coal, petroleum coke, biomass, and municipal solid wastes, either alone or in combination. The GTI gasification technology has been developed and tested with over 25 different feedstocks from around the world, including various forms of biomass, municipal wastes, metallurgical cokes, and all ranks of coal from lignite through bituminous. The GTI gasification process can provide a means for industry to cost effectively cope with rising fuel costs and environmental restrictions. "
