A model for the dynamic behavior of both reactant and product in heterogeneous catalysis for the evaluation of rate Parameters is presented, An analytical solution is obtained for the case in which only adsorption equilibrium and first order irreversible reaction are involved. The treatment of the overlap of reactant and product in effluent stream and the ease of non-linear adsorption are described.

For the first order reaction on a fractal surface, the reaction rate constant is assumed to be time dependent, and the kinetic expression takes the form: CA=CA0 exp (-k’t2/d), where k’ is a constant and dw is the fractal dimension of the trajectory. For two types of fractals, Sierpinski gasket and percolation cluster, Monte Carlo simulations show that the expression can effectively describe the kinetics of the first order reaction on the fractals.

During the last 2 years, heat flow data increased significantly in China as a result of implementation of many comprehensive geodynamic (including geothermal) projects and GGT project in China. In this paper, a total of 366 reliable heat flow data is collected from published and in press sources in the Compi-ilation of Heat Flow Data in the China Continental Area (2nd edition). Statistic analysis of these data shows that the heat flow values in China continental area vary from 20 to 140 mWm-2. The mean value appears to be 66 mWm-2.

Since heat flow bears valuable information on energy balance between various processes occurred at depths, heat flow data attract more and more attention of earth sciences communities. In China, 3 heat flow values from the Mesozoic basin of NE China were reported in 1966, but the quality and accuracy seemed to be unsatisfactory. The first portion of 25 reliable heat flow data was published by

Polyacrylonitrile (PAN)-based activated carbon fibers (ACFs) are amorphous graphitic carbon, consisting of sp2 hexagonal carbon layers with different sizes of pores ranging from micropores to macropores. The microstructure, including graphite-like microcrystal, surface chemistry, pore size distributions and so on, of PAN activated carbon fibers prepared by different activation methods were investigated by element analysis (EA), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and infrared spectra. The XRD patterns show that PAN-ACFs activated by different methods are of amorphous diffraction characteristic but composed of very small graphitic crystallites. The surface functional groups were analyzed by XPS and FT-IR spectra. The samples activated by potassium hydroxide posses less oxygen functional groups, and the samples activated by potassium hydroxide possess less oxygen functional groups. This is attributed to the different activation mechanisms.
