Investigating Efficient Tar Management from Biomass and Waste to Energy Gasification Processes.

摘要

This effort evaluates enhancements to future development of deployable waste-to-energy (WTE) systems that meet Department of Defense (DoD) needs for efficiency, footprint and reliability. Waste materials and biomass are an energy resource which can be gasified and combusted in electricity generation. Coproduced gasification tars and gas cleanup complicate utilization and reduce conversion efficiency while posing environmental risk. The classical approach breaks tars down completely to carbon monoxide and hydrogen and then combusts these molecules or uses them in liquid fuel production. Literature shows, however, that many of these tars are flammable liquids that would burn in internal combustion engines (via the liquid fuel injection system) with better thermodynamic yield than burning the reformation product of the liquids.
