New Publication – Round Robin results of biomass liquefaction oils

Feb 2021

Solid biomass can be liquefied using a range of technologies including fast pyrolysis, hydrothermal liquefaction (HTL), and solvothermal liquefaction. More information can be found here:

In the frame of IEA Bioenergy Task 34, a round robin study was performed to evaluate the analysis of biomass liquefaction oils (BLOs) from fast pyrolysis and hydrothermal liquefaction (HTL), receiving data from 14 laboratories in seven countries in order to assess the current status of analytical techniques for the determination of nitrogen, sulphur, and chlorine content in biomass liquefaction oils and to evaluate potential differences in origin (i.e., fast pyrolysis versus HTL). The BLOs were produced from a range of feedstocks including pine, mixed softwoods, forest residues, microalgae, miscanthus, and wheat straw to cover a variety in nitrogen, sulfur, and chlorine content and speciation.
