Abstract: Biomass is one of the most promising energy feedstocks because of its unique properties: renewable, carbon-neutral and environmental friendly. Different from other thermochemical biorefineries, advanced hydrothermal liquefaction (HTL) biorefineries can use pressurized hot water to directly convert wet biomass & waste streams (e.g., black liquor and hog fuel) into marketable bio-crude oil and other types of bioproducts. Corrosion data about alloy performance in pressurized hot water with the presence of catalysts and corrodants are scarce, making costeffective selection of alloys of construction difficult. To meet the industrial demands, thermodynamic calculation, static autoclave tests and advanced microscopic characterizations have been performed to investigate corrosion modes and extents of candidate alloys under such unique conversion conditions. This paper introduces some most recent results obtained.
