The kinetic models of chemical reaction of fluids on rough surfaces

The kinetic models of chemical reaction of fluids on rough surfaces have been established by the Mandelbrot's concepts of fractal geometry (dimensionless expression: 1-(1-chi)(1-betaDx/3)=t/t(1), chi-conversion ritio, beta-concentration level, D-s-fractal dimension, t(1)-reaction and time). The moldels are in good agreement with the experimental data of the coke-CO2 reaction (the calculated apparent active energy being 54.814 kJ/mol) and have clearer physical understanding as compared with the traditional shrinking unreacted core models which are the special forms of the fractal models under the conditions of regular geometry.
