Research Interests

Kim Magrini is a principal research scientist and group manager in the National Renewable Energy Laboratory's (NREL) National Bioenergy Center (NBC). She manages NREL's Catalysis and Thermochemical Sciences Group, which focuses on the development of catalytic approaches to biofuels production from syngas and pyrolysis. She has 25 years of research and management experience in academic, industrial, and national laboratory environments and has more than 80 peer-reviewed publications, 1 patent, and 110 presentations at national and international meetings. Her research areas include catalyst development for syngas conditioning, hydrogen production, thermochemical fuels and chemicals production from pyrolysis liquids and vapors, power production, and rapid comprehensive characterization of soils and chars using pyrolysis molecular beam mass spectrometry. She is currently leading a team to produce hydrocarbon fuels via catalytic upgrading of biomass pyrolysis vapors using a Davison Circulating Riser (DCR) reactor system. When not at NREL she can be found flying her Piper Turbo Arrow around Colorado.

Figure of NREL's pyrolyzer/Davison Circulating Riser (DCR) comprised of the biomass pyrolyzer on the left and the three reactors of the DCR unit, which makes hydrocarbon fuels from the biomass pyrolysis vapors. Above the system schematic is a process diagram that shows how biomass feedstock moves through the pyrolyzer to make vapors that are fed into the DCR reactors. Liquid products are collected in a product tank located under the DCR stripper reactor.

Figure of bright red, green, yellow, blue, and dark blue splashes on a bright blue background, with pink, blue, and yellow lines undulating from left to right. The figure shows a chromatogram of the DCR products that are analyzed with a two-dimensional gas chromatograph/mass spectrometer system. The product types are shown in similar colored areas: green and red are paraffins, yellow is 3-ring aromatics, red only is 1-ring aromatics, pink is phenolics, dark blue is 2-ring naphthalenes, and blue represents 2-ring aromatics.
