High temperature CO 2 and SO sequential capture in a bubbling fluidised bed was investigated using natural limestone synthetic composite pellets. Calcination conducted under oxy-combustion conditions, while carbonation sulphation occurred an air-combustion atmosphere. The goal of /SO is to desulphurise the flue gas first, followed by cyclic calcination. Here, fresh sorbent first used calcinatio...

The GC monitoring of green house gases is a challenging task because the concentration of organic species such as methane are relatively low (ppm to ppb) and their analysis requires some level of preconcentration. Since methane is highly volatile, it is not easily retained on conventional sorbents. In this paper we present multiwalled carbon nanotubes (MWNTs) as an effective sorbent for a micro...

The study outlines a novel and traceable procedure for inactivating zinc polluted soil (an Anthrosols) adjacent to former (Zn) ore mine “Orzel Bia?y” in Bytom (Poland), where the total content of Zn amounted 3988.0 mg kg?1. This pollution level initiated an inactivation process involving two natural mineral sorbents, i.e., zeolite (Z) bentonite (B), as well their five blends (ZeoBen) expressed ...

This paper presents the results of evaluation possibility using a selected sorbent natural origin, mineral (opoka rock), for removal biogenic compounds from aqueous solutions. The analyzed opoka rock contains approximately 70% calcium carbonate (CaCO3) and 26 to 27% silicon dioxide (SiO2) has been classified as heavy rock. experiment focused on sorption organic components, including phosphorus ...

In the conditions of progressive contamination surface sources water supply and inefficient wastewater treatment when using existing technologies, research problem justification use sorption materials for retention specific pollutants, in particular heavy metal ions radionuclides, is urgent. The parameters that determine efficiency sorbents are indicators their sedimentation rate. purpose exper...

Carbon capture is among the most sustainable strategies to limit carbon dioxide emissions, which account for a large share of human impact on climate change and ecosystem destruction. This growing threat calls novel solutions reduce emissions an industrial level. by amorphous solids reasonable options as it requires less energy when compared other techniques has comparatively lower development ...
