“…Those slags play a major role in the design of CO 2 -emissionreduced power plants in which coal is gasified with the help of an appropriate reactor (Integrated Gasification Combined Cycle [20,21]). Due to extremely high temperatures in this gasification step, ash particles from the coal occur in liquid form (slag) and represent a danger for the subsequent gas turbine process.…”

a b s t r a c tA new method based on the Young-Laplace equation for measuring contact angles and surface tensions is presented. In this approach, a first-order perturbation technique helps to analytically solve the Young-Laplace equation according to photographic images of axisymmetric sessile drops. When appropriate, the calculated drop contour is extended by mirror symmetry so that reflection of the drop into substrate allows the detection of position of the contact points. To keep a wide range of applicability, a discretisation of the drop's profile is not realised; instead, an optimisation of an advanced image-energy term fits an approximation of the Young-Laplace equation to drop boundaries. In addition, cubic B-spline interpolation is applied to the image of the drop to reach subpixel resolution. To demonstrate the method's accuracy, simulated drops as well as images of liquid coal ash slags were analysed. Thanks to the high-quality image interpolation model and the image-energy term, the experiments demonstrated robust measurements over a wide variety of image types and qualities. The method was implemented in Java and is freely available [A.F. Stalder, LBADSA, Biomedical Imaging Group, EPFL,

“…It was reported that MDEA can deliver performance comparable with the physical absorption processes when the pressure of the gas stream is not very high. 10 Once the sulfur is removed, the clean syngas can be sent to the power generation block for combustion. Because CO is still in the syngas stream, carbon in the coal is not captured in this scenario and will be emitted from the combustor exhaust in the form of CO 2 .…”

“…Use of porous ceramics enables low-cost and maintenance-free continuous processing of gas separation filters. Therefore, it is expected that application of these filters to energy and environmental engineering, e.g., carbon dioxide capture and storage (CCS), 53) integrated coal gasification combined cycle (IGCC), 54) and so on, will intensify. Instruments designed for particle dispersion have been developed on the basis of dispersion data.…”

The interaction between solid surfaces was evaluated by scanning probe microscopy using a colloidal probe. The dispersant provided a repulsive force between the solid surfaces at less than 30 nm. On the other hand, the binder provided a bridging force between the solid surfaces for retraction at less than 500 nm. Because of the complicated nature of the forces acting between the surfaces, the separation distance between ceramic particles (SDP) was calculated. Moreover, the relation between the agglomeration/dispersion of Al 2 O 3 particles and the calculated SDP were discussed. As an extension of these results, Al 2 O 3 pastes were prepared for tape casting from a viewpoint of the SDP. The tape casting of nanoparticles, which is generally difficult, was successful. On the basis of these fundamental studies applied to environmental functional materials, porous ceramics having oriented pores were prepared by an extrusion method. The obtained porous ceramics demonstrate high capillary action and are used for the relaxation of an urban heat island. Porous ceramics having nano-sized pores were prepared by a slip casting method. The porous filter has CO 2 gas separation ability by using surface diffusion.
