Abstract
Conversion of lignocellulosic biomass to fuels and chemicals is a potential way to ease our fossil fuel addiction. Catalytic fast pyrolysis, hydrodeoxygenation, and partial oxidation, the three important processes in a biorefinery, are of my interests. Catalytic fast pyrolysis is a one-pot process by which solid biomass (e.g., cellulose) can be directly converted to liquid fuels (e.g., aromatics) in an inert environment. Pyrolysis temperature, heating rate, and zeolite design are keys to manipulate product distribution. Hydrodeoxygenation extracts oxygen from biomass framework to yield hydrocarbons through hydrogenation, releasing water as the byproduct either under high or ambient H2-pressured conditions. Sulfided and phosphided nickel catalysts are effective in lignin hydrodeoxygenation, and a detailed hydrodeoxygenation mechanism was explored. Partial oxidation under an autothermal mode allows rapid conversion of biomass waste, e.g., glycerol, into syngas at millisecond contact times. Thermally stable perovskite is a promising candidate in oxidative, high-temperature environments for biomass partial oxidation to syngas. An integrated study of computational chemistry, reaction engineering, and catalyst design of aforementioned research fields is currently ongoing, and is deemed to be critical for the practice of lignocellulosic biorefinery.
