Basic research of the thermochemical conversion (pyrolysis, gasification, combustion) of biomass particles.

Continuous determination of the concentrations of O2, CO, CO2, H2O, H2, OGC, NO, NO2, HCN, NH3, HCl, SO2 and various hydrocarbon compounds during the thermal conversion steps.

Determination of the release of inorganic aerosol forming elements (e.g., S, Cl, K, Na, Zn and Pb) by coupling the reactor with an inductively coupled plasma mass spectrometer (ICP-MS).

Methods & Expertise for Research Infrastructure

The reactor concept was designed for the description of thermal conversion processes (gasification, combustion, pyrolysis) of single biomass particles. With the reactor, targeted investigations under the desired atmosphere (usually mixtures of N2 and air or N2) up to a temperature of 1050 °C are possible. A very wide range of analysis devices can be connected to the reactor, whereby release data from inorganic aerosol-forming elements (eg S, Cl, K, Na, Zn and Pb) are generated by a connection to an inductively coupled plasma mass spectrometer (ICP-MS).
So far the reactor has been used for the determination of the time-resolved release of relevant aerosol forming elements from different biomass pellets at 3 different temperatures. These data lead to an improved understanding of the release of inorganic ash forming elements and is the basis for model development. Moreover, the reactor has proven its applicability to describe pyrolysis processes of single particles.

The single particle reactor is a self-development, where trained staff is needed to carry out the test runs. Research objectives as well as other tests can be adapted individually if necessary. Specific conditions of use on request.
