In situ performance of various metal doped catalysts in micro-pyrolysis and continuous fast pyrolysis

open access: yesFuel Processing Technology, 2016
Abstract Catalytic fast pyrolysis (CFP) of biomass is a promising route for the production of deoxygenated liquids suitable for further conversion to fuels and/or chemicals. In this work, CFP of pine wood in a micro-pyrolysis setup and a continuously operated bench-scale fast pyrolysis unit was performed to investigate the effect of catalyst type and

On the Friction and Wear Mechanisms of Electrified Steel Contacts in CO2: Unveiling the Role of Carbon‐Rich Tribofilms Under Dry Sliding Conditions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates friction and wear of AISI 52100 steel under dry sliding in CO2, air, and N2 atmospheres, with and without contact electrification. CO2 forms a stable carbon‐rich tribofilm that reduces friction by ∼30% and wear by ∼85%. High‐resolution TEM, EELS, and molecular dynamics reveal pressure‐dependent lubrication mechanisms, showing ...
