A Mini-Pilot HTL Reactor for Production of Fuel Intermediates from Biomass Wastes

Short Introductive summary

Hydrothermal liquefaction (HTL) is a thermochemical process that takes advantage of the water in the feedstock, at process conditions where the heat of evaporation for water is avoided and hence pre-drying is not necessary. A continuous lab-scale HTL mini-pilot system Was installed at the end of 2019. The mini-pilot has a capacity of maximum 2 L/h slurry feed and is able to operate at state-of-the-art conditions, i.e. up to 500 °C and 350 bar. The reactor is built with a research focus, for studying operational issues, such as fate of inorganics, corrosion and the effect of depressurization on those. The system has the possibility to include stress loaded corrosion samples for material and weld testing under real HTL environment. To facilitate this objective, a relatively large compartment was needed to insert the samples, therefore, a CSTR reactor was selected. The mini-pilot is equipped with dual piston pumps and a two-stage depressurization system to study the depressurization effect on the product composition and distribution. Details about the reactor system as well as the first results will be discussed.

Presenter's biography

I am working on thermochemical processing technologies such as hydrothermal liquefaction, pyrolysis and gasification. Earlier, as a student researcher and master student, I got insight into cellulosic bioethanol technology.
