Method of measuring wettability of brown coal, in particular chemically modified, in order to assess the possibility of its biofluidification

摘要

The purpose of the notification is to measure the susceptibility of brown coal, in particular chemically modified coal, in order to assess the potential for its bioliquidation, which is that the coal is crushed into powder and then made from coal powder into a tablet,the reconstituted tablet is then coated with a liquid coloured with a contrast dye and, immediately after application, the 3-D image of the tablet is recorded with a part of the substrate using an infrared beam from the source of the optical radiation set of the coherent OCT.a pre-treatment of the recorded 3D OCT image of the droplet by the reduction of arc noise and further separation of the droplet and the substrate from the background on the OCT image by segmentation of that image through global projection. Next, an approximation of the drop base plane is madeconverts the binary image from Cartesian to cylindrical coordinates with the angular resolution of the 1st and vertical axis of the cylinder passing through the tip of the drop to obtain 360-cross for one 3D OCT image and traces the profile of the drop from the top to the bottom on the individual angular cross-sections, then an approximation of the profile of the drop is made by the second degree of multiplication from the height of 30 pixels above the ground, calculates the single moisture angle as the angle of intersection of the multiplicate with the line of the substrate on each section, finally calculates the mean moisture angle for all the corner sections of the drop depending on model 1,Which one? Y stands for the average angle of humidity of the test carbon sample, what? and the mean cosine of the moisture angles visible in all directions of the substrate with precision 1,r= AT/AP is the mean soil chromaticity factor of a given type of carbon expressed by the ratio of fields of the surface of the triangular AT and approximated AP.
