Equipment & Facilities
The IIC is a virtual organization that facilitates collaborative synergistic research among scientists and engineers across the Pacific Northwest National Laboratory campus and around the globe. In that context, IIC facilitates the deployment of a range of facilities controlled, managed and supported by other organizations (see our flier Experimental and Computational Capabilities for 21st Century Catalysis Research [pdf, 364kb]). Among these is a powerful and extensive portfolio of leading-edge experimental and computational resources for catalysis research located in the Environmental Molecular Sciences Laboratory (EMSL), a DOE BER-supported national scientific user facility on the PNNL campus. These resources are available for collaborative, independent, and proprietary research by the external scientific community of universities, other federal laboratories, and industry, as well as the internal PNNL staff. Access to these facilities is governed by a proposal process administered by EMSL. For more information, potential users should access the EMSL website. A summary of EMSL capabilities typically relevant in catalysis is given below. More detailed listing can be found on the EMSL website.
In numerous other locations across the PNNL campus, the catalysis science and engineering facilities include a range of reactor systems for scale-up (bench-to-pilot scale):
- Chemical Engineering Laboratory
- Chemical Process Development Laboratory
- Process Development Laboratory-East
Additional applied catalysis research work, including catalyst synthesis, bench-scale testing, and catalytic process development, is conducted throughout the Laboratory:
- Chemical and Biological Process Development
- Advanced Processing and Applications
- engine emission test Applied Process Engineering Laboratory (APEL)
- Mobile Process Engineering and Demonstration Unit
- Physical Sciences Laboratory
- Combinatorial Catalyst Lab at PSL
- Advanced Photon Source. PNNL is a member of the Advanced Photon Source PNC-CAT beamline (Sector 20) at the Argonne National Laboratory. The experimental capabilities of the beamline include in-situ X-ray absorption fine structure (XAFS), X-ray scattering, reflectivity, and imaging. The X-ray scattering will include application of the diffraction anomalous fine structure (DAFS) and X-ray resonant inelastic scattering (XRIS) techniques.
