Enabling Gasification of Blended Coal, Biomass and Plastic Wastes to Produce Hydrogen with Potential for Net Negative Carbon Dioxide Emissions


Projects funded under this FOA must perform R&D to address a technology gap that would achieve objective(s) as described in the following area of interest (AOI):
  Co-gasification of Coal, Biomass and Plastic Wastes for Production of Hydrogen and Fuels with Negative Carbon Potential.
This AOI seeks R&D that accomplishes the required element and one or more of the optional elements listed below:

  •  [Required] Experimental analysis of a gasification process using the coal/plastic/biomass feedstocks as prescribed later under this AOI. Experimental process conditions and feedstock blend(s) proposed in the testing campaign must be justified as being commercially relevant.
  • [Optional] Experimental analysis of slag characteristics such as melting behavior, crystallization behavior, interaction with refractory, and viscosity along with ash fusion temperatures when gasifying the above.
  •  [Optional] Experimental analysis of pre-treatment requirements for combinations of waste plastics, coal and biomass. Such pre-treatment may include, but is not limited to, adjusting size, shape or density for consistent feeding of the blended feedstock.
  •  [Optional] Experimental analysis of contaminants, impurities, and catalyst poisons that may inform process requirements to clean up and upgrade the hydrogen content of the raw syngas resulting from blended feedstock co-gasification.

Applicants are encouraged to standardize on the following mixture of plastics when adding plastics to coal and biomass feedstocks. The mixture of plastics is based on findings in a report from the Army Research Laboratories (ARL-TR-7394, 2015, . . . Applicants may elect to study a different mixture of plastics as a blend stock with coal and biomass; however, deviations from the suggested mixed plastics must be justified as having commercial relevance.
