About the Lab
Professor Ji Hoon Han's research lab specializes in sustainable biorefining and carbon utilization, focusing on the catalytic conversion of lignocellulosic biomass and biomass-derived oxygenates into advanced biofuels and high-value chemicals. The lab develops integrated process strategies that maximize resource efficiency by co-producing liquid hydrocarbons, hydrogen, and chemical intermediates while minimizing environmental impacts. Key research directions include electrocatalytic oxidation of biomass derivatives, life cycle assessment of bio-based processes, and the design of scalable infrastructure for carbon dioxide utilization and storage. The lab emphasizes techno-economic feasibility and sustainability assessment to support the transition toward low-carbon, circular bioeconomies.

15We develop and evaluate an integrated catalytic conversion strategy, which utilizes both the hemicellulose and cellulose fractions of lignocellulosic biomass to produce liquid hydrocarbon fuels (butene oligomers). In this strategy, the cellulose and hemicellulose fractions are simultaneously converted to levulinic acid (LA), using LA-derived γ-valerolactone (GVL) as a solvent. The LA is then converted to GVL, which is subsequently converted to butene, and then to butene oligomers. To generate th
The electrocatalytic oxidation technology of biomass-derived oxygenates such as glycerol presents a promising method of coproducing renewable chemicals and hydrogen in an electrochemical reactor system that uses oxidation chemistry and existing proton exchange membrane technology to electrocatalytically convert oxygenates into value-added chemicals and hydrogen. In this paper, we first demonstrate the techno-economic feasibility of the electrocatalytic glycerol oxidation technology with our expe
An integrated assessment method for co-production pathways can give reliable results to decision makers for sustainable development of biorefineries.
Much of the previous research on carbon capture and storage (CCS) has focused on individual technologies for disposing of CO 2, such as capture, storage, sequestration, or transport. Moreover, recent research work considers utilization of CO 2 as fuels, chemicals, or nutrients for bioreactors. To efficiently manage CO 2 and the economic benefits achieved by this process, the CO 2 transport and processing infrastructure supporting CCS will have to be constructed at a macro-scale. This paper intro
A cradle-to-gate life cycle assessment provides comprehensive insights into diverse environmental impacts and possible improvements in producing two formic acids.
Our work aims to identify critical factors that could become equally important in a coincident sustainability assessment of new green energy vehicle technologies with utilization of food waste as an alternative renewable resource to fossil fuels.
