Under Pressure: The thermochemical conversion of biomass to fuels and platform chemicals is on its way to industrialization. Biomass is readily abundant and inexpensive, and the conversion to fuels is nearly carbon-neutral, sustainable, and renewable. The focus of this work is on catalytic fast pyrolysis and hydropyrolysis, which occur at moderate temperatures and heating rates. Specifically, we study the effects of pressure and catalyst choice on the pyrolysis product yields as a means to improve the catalyst deoxygenation capacity and reduce the excessive production of char and coke. The pyrolysis bio-oils typically lacks high heating values; to improve energy content the authors investigated the viability of adding high-pressure hydrogen to the pyrolysis reactor. Co-feeding hydrogen at high pressure over a Ni-ZSM-5 catalyst increases selectivity to mono-aromatic hydrocarbons, with a parallel enhancement of the yield to saturated products. Additionally, the coke and char yields are drastically reduced, while methane selectivity increases significantly. The authors gratefully acknowledge Victoria Probert for the cover design.
