Hydrothermal liquefaction (HTL) is an important thermochemical technology which uses hot pressurized water to convert wet biomass or biowaste feedstocks into biocrude oils and other marketable bio-chemicals. However, the widespread commercialization of HTL technology could be challenging due to the corrosion of process core equipment, especially the refining reactors. The presence of hot pressurized water, aggressive catalyst, and organic products can lead to serious corrosion damage and even stress corrosion cracking risks on HTL reactors. Lignocellulosic biomass comprises three primary components: cellulose, hemicellulose, and lignin. These components exhibit distinct behaviors during HTL conversion, leading to variations in the chemical environment and properties of the resulting products. This study aims to compare the corrosion modes and extents of a typical austenitic alloy (UNS R20033) under HTL of three typical biomass model compounds (cellulose, xylan, and alkali lignin) to facilitate the development of corrosion mechanisms in biomass HTL environment.

The conversion of forestry/agricultural residues (lignocellulosic biomass) to biofuels or bioproducts has received increasing interest over the past years because of the demand for green products and the fact of abundant residual/waste streams in forestry and agricultural sectors. Forestry/agricultural residues/waste streams are advantageous bioresources to produce biofuels or bio-based chemicals since they do not compete with food resources.¹ Typical conversion technologies involve biochemical and thermochemical processes. Biochemical conversion processes, mainly referring to fermentation of wet carbohydrate materials into bioethanol and anaerobic digestion to generate biogas at ambient operation conditions,² is quite slow and sensitive to operating conditions (pH, temperature, etc.).³
