(632a) Processing Carbonaceous Feedstock Using Ionic Liquids for Sustainable Carbon Engineering
One promising alternative is to develop a hybrid feedstock system. This hybrid energy system by combining biomass with other carbonaceous feedstocks in a single conversion platform would reduce supply fluctuations, mitigate GHG emissions, and be more politically palatable. However, current research has mostly focused on thermochemical conversion of single type of feedstock at high temperature and elevated pressure, which requires high energy consumption. Developing low energy, environmental benign, feedstock agnostic technologies, is critically important to address concerns of energy security and process economics. Ionic Liquids (ILs) as a class of novel environmental benign solvents are receiving increased attentions. Many researches have focused on ILsâ?? applications in lignocellulosic biomass dissolution for biofuels production, while the work on blending biomass with other feedstock sources to reduce the supply cost and improve the conversion efficiency is limited. This works looks into the feasibility of processing woody biomass mixture with other carbonaceous feedstocks using IL solvents for production of clean energy and high valuable materials. Various types of ILs and feedstocks, and process conditions are investigated. The IL processed carbonaceous materials are further characterized for their compositional, physiochemical and rheological properties changes to advance process optimization and development towards an economic feasible carbon engineering technology by employing wide range of regional feedstocks.
