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.
