Experimental studies of the course of CO2/CH4 exchange sorption on hard coal subjected to confining pressure.

(Corresponding) Skoczylas N.

Topic:

Gas emissions control and utilization

Studies were carried out on exchange sorption of CO2/CH4 on four samples of hard coal differing in the degree of coalification. The samples were subjected to various confining pressures in the range from 1.5 MPa to 30 MPa. The author's conception of the measuring apparatus made it possible to...Read more

Effect of confining pressure on sorption parameters and structure of coal in terms of analyzing the possibility of underground CO2 storage with CH4 recovery.

(Corresponding) Pajdak A.

Topic:

Gas emissions control and utilization

An original apparatus was constructed, allowing observation of sorption processes occurring in hard coal briquettes. The investigations were carried out on four hard coals from Poland and France differing in the degree of coalification. The coal briquettes were subjected to confining pressure with...Read more

Laboratory studies of coal permeability under conditions corresponding to in situ, in terms of assessing the possibility of underground CO2 storage with CH4 recovery

(Corresponding) Kudasik M.

Topic:

Gas emissions control and utilization

Investigations of processes accompanying the exchange sorption of CO2/CH4 under confining pressure in the range of 1.5 MPa to 30 MPa have been carried out. The research was carried out on innovative apparatus for testing filtration, sorption and CO2/CH4 exchange sorption processes under isobaric...Read more

Utilization of alkaline converted ash blends from lignite and biomass combustion for carbon capture

(Corresponding) Boycheva S., Dimitrov M., Zabov E., Winter F., Popova M.

Topic:

Gas emissions control and utilization

The replacement of fossil fuels by renewable biofuels is one of the ways to limit climate change and improve the quality of the atmospheric air. For existing solid fuel combustion plants, a partial replacement of coal with biomass from wood or agriculture waste is applied. In this paper the effect...Read more
