About the event

The Gene and Linda Voiland School of Chemical Engineering and Bioengineering is hosting a seminar presented by Jenny Voss, M.Sc. Student, Voiland School of Chemical Engineering and Bioengineering, Washington State University.

Jenny Voss is originally from Grays Harbor County located along the Pacific Ocean in southwest Washington. She earned a Bachelor’s Degree in Chemical Engineering (minor in chemistry) accompanied by two petroleum sector internship appoints at BP Alaska Co. and Phillips66 Ferndale refinery from the Washington State University in Pullman, WA in May of 2015. The following fall semester she began her research efforts toward a Doctorate degree in chemical engineering with Professor Norbert Kruse as an ARCS Fellow. Her research focuses on the catalytic reaction of H2 and CO2 into chain lengthened hydrocarbons and alcohols for use as transportation fuels and fuel additives over bimetallic cobalt-copper catalysts promoted with the alkali metal potassium. Catalytic high pressure reactor studies were favored to determine the influence of K on the catalytic activity of Co-Cu catalysts. While in Pullman, Jenny was appointed as a GPSA representative on the President’s University Budget Committee aimed at the allocation of Student Activity Fees to dozens of registered organizations and essential university facilities. She won second place best poster at the Research Exposition Expo sponsored by GPSA in the spring semester of 2017. Shortly afterwards in the summer of 2017, her research focus shifted toward determining the 3-Dimensional atom-by-atom elemental mapping of these K-promoted Co-Cu catalytic nanoparticles using Atom Probe Tomography at the Environmental Molecular Sciences Laboratory (EMSL) located on the Pacific Northwest National Laboratories (PNNL) campus residing in Richland, WA. Her move to EMSL was motivated by the award of the NSF GRFP, DOE SCGSR and PNNL-WSU Distinguished Student program appointments. She has presented her work at the annual AiChE (2016) and bi-annual APTM (2018) conferences and published one peer reviewed journal article up-to-date. Notably, Jenny greatly enjoys going hiking in the wilderness, athletics, spoiling her niece and nephew, and taking her dog with her to events whenever she gets an opportunity to do so.

Catalytic reaction of H2 and CO2 over K-promoted bimetallic CoCu catalysts.

The recycling of CO2 into alcohols for use as transportation fuel additives has gained recent interest over the years in efforts to reduce anthropogenic carbon footprint on the environment. Higher alcohols are valuable for use as fuel additives to improve octane number, engine efficiency and reduce exhaust emissions. Herein this presentation, she will explore the influence of a K-promoter on the CoCu catalytic system aimed at the hydrogenation of CO2 into alcohols. Her research focuses on the developing activity-structure relationships of the K-CoCu catalytic system. Catalytic high pressure tests give insight into the influence of K on the behavior of CoCu catalysts. The research herein found a K-promoter tuned selectivity from that of mainly CH4 to chain-lengthened hydrocarbons and alcohols. The influence of K on the structure of the Co-Cu system is gleaned using techniques such as, X-ray Diffraction, Temperature Controlled Decomposition, Transmission Electron Microscopy, and 3D Atom Probe Tomography. The Co-Cu catalyst were found to consist of patches of metallic cobalt and copper co-existing within the same particle. Ultimately, her research aims to provide to the research community a tool for strategically design future catalysts for directly recycling CO2 into higher alcohols.
