Petit C, Ferguson T, Park AHA, 2012, Carbon negative production of hydrogen from biomass using an alkaline thermal treatment: Kinetic and mechanistic studies for the investigation of the reaction pathways

Using biomass as a feedstock in place of fossil fuels for the production of energy and fuels can represent a sustainable alternative since this energy source is renewable, carbon neutral, and globally distributed. In this study, the one-step H2 production from biomass using an alkaline hydroxide (i.e., NaOH) under mild reaction conditions (i.e., 373 - 573 K, 1 bar) was investigated using a model biomass system. This method has great potential since it enables the production of a high-purity H2 stream with increased yield. Moreover, it is carbon negative since the carbon in the biomass is converted to a solid, environmentally benign carbonate. Owing to the suppressed CO formation in this process, the produced gas can be directly used in subsequent energy conversion systems such as PEM fuel cells without additional gas cleanup steps. The formation of gaseous products (i.e., H2, CH4, CO and CO2) during the reaction was monitored using gas chromatography, and the characterization of the derived solid products was carried out using 13C NMR and Raman spectroscopies, while investigating the effect of the reaction conditions (i.e., final reaction temperature, reactants ratio). The findings of this study provided important information regarding the mechanistic pathways of the alkaline thermal treatment of biomass for sustainable energy conversion.

Petit C, Park Y, Lin KA, Park AHAet al., 2012, Novel liquid-like nanoscale organic hybrid materials for CO2 capture

New solvents referred to as Nanoparticle Organic Hybrid Materials (NOHMs) are being developed for various energy and environmental applications, with a particular focus on CO2 capture. These nanoscale hybrid materials consist of an inorganic nanocore functionalized with a polymeric canopy, which acts as the solvating medium. Compared to the conventional amine-based solvents, NOHMs exhibit valuable properties such as negligible vapor pressure and high thermal stability. CO2 capture by NOHMs is expected to arise from two properties: the tunable chemistry of the canopy via selection of task-specific functional groups, as well as the specific structural arrangement of the polymer chains, favored by decreases in entropy. In this study, different NOHMs were synthesized and they were characterized using thermogravimetric analysis, spectroscopic tools (i.e., NMR, Raman, ATR FT-IR), and viscosity measurement techniques. The CO2 capture and CO2-induced swelling behaviors of NOHMs were evaluated and the mechanisms of CO2 absorption were investigated. The effects of the canopy structure (e.g., grafting density, polymer geometry), the canopy functionalization (e.g., presence of amine groups), and the presence of other flue gas components (e.g., N2, SO2, H2O) on the overall CO2 capture process were studied.
