High-alkali coal is abundant and can cope with the current energy supply and demand gap.
However, the sustainable utilization of high-alkali coals is limited by their abundance of …

Alkali metal compounds are released during the thermal conversion of biofuels and fossil
fuels and have a major impact on the efficiency of conversion processes. Herein, we …

In this work, we present rigorous calibration and assessment of a surface ionization detector
(SID) for alkali monitoring in industrial process gases and compare it to an in situ laser …

Oxygen-carrying fluidized bed materials are increasingly used in novel technologies for
carbon capture and storage, and to improve the efficiency of fuel conversion processes …

A novel method for online speciation of potassium-and sodium-containing compounds has
been described and demonstrated. The method is based on a temperature-modulated …

To assure stable cesium injection for negative ion source, the surface ionization detector
(SID) is applied for diagnosis. Consisted of emitter and collector, the SID is operating based …

Chemical looping combustion (CLC) of biomass is a heat and power generation technology
with minimal associated costs for carbon capture, potentially resulting in negative CO2 …

High alkali content is an important feature of biomass, and it has a series of implications for
thermal conversion processes. This thesis focuses on the release of alkali during various …
