Palladium-based Sorbents for Trace Metals
Palladium-based sorbents are among the most promising candidates for the high-temperature, one-step capture of trace elements from coal-derived fuel gases, which will reduce the footprint, cost, and complexity of pollution mitigation. In a separate but related research effort to RTI's warm gas cleanup, NETL will focus on testing and developing palladium sorbents for the capture and removal of trace metals like mercury, arsenic, selenium, phosphorus, and cadmium (co-capture). Capacity for capture will be determined in simulated fuel gases through the use of laboratory-scale packed-bed reactors and at larger scales in slipstreams of real fuel gas at an actual gasification facility. Warm gas cleanup research promotes the utilization of abundant domestic coal in a clean and environmentally friendly manner. Technology developed under this project will allow gasification to meet stringent EPA regulations for trace metal emissions.

CO2 Capture and Sequestration Technology Development
DOE has a significant program in CCS. For gasification, commercial technologies are available for pre-combustion CO2 capture, for near-term applications. Mid-term and longer-term technologies under development include:
- Solid sorbents
- Physical solvents
Further information in this area is available at the Innovations for Existing Plants (IEP) Program's CO2 emissions control R&D homepage and more specifically, the pre-combustion CO2 control page.
