Researchers push gasification pyrolysis as a means to more affordably process wood and other substances into biofuel
Germany is now setting its sights on biofuels. Researchers at the Karlsruhe Institute of Technology (KIT) are working on a process to create relatively affordable biofuels out of common plant wastes, such as waste wood.
They hope the technology will yield fuel that costs €0.50 a liter or $2.49/gallon USD. However, it is dependent on the proper infrastructure being established, says the team.
The new process breaks down wood, straw, or other plant waste by a process known as bioliq. It yields a number of fuel products that could be refined, to produce gasoline, as well as other useful chemical byproducts.
The key obstacle the team foresees to syngas biofuels is the transportation of plant waste and the costs incurred. The team plans to split the pyrolysis process from the gasification. The pyrolysis would occur at numerous smaller plants, which would then deliver biosyncrude to a central plant for gasification. This structure would be more feasible than a design featuring a two phase central plant, they say.
