Abstract: Many different processes are used to treat raw natural gas to pipeline quality. The sulfur is commonly present as an impurity in fossil fuels. Magnetic field is applied in a fluidized bed which contains nano activated carbon to investigate hydrogen sulfide elimination, in this paper. Sulfur removal in this way is presented experimentally and theoretically. The rate of mass transfer is introduced as function of gas temperature, amount of balls covered by nano carbon tubes, initial concentration of hydrogen sulfide, gas flow rate and also, magnetic field. The experimental data are presented and compared with the model results. The effect of hydrogen sulfide in the inlet sour gas on the mass flow rate in investigated in this paper. In addition, the effect of porosity percentage of catalytic bed on the hydrogen sulfide content of outlet gas is evaluated in this paper. The outlet concentration below 4 ppm is acceptable result due to commercial rules. The experimental data are in higher values of hydrogen sulfide comparing with the ones from modeling data.

Abstract: Division of coalbed methane (CBM)-enriched units primarily depends on the analysis of the main controlling factors of CBM occurrence. The main controlling factors analyzed in this article are sedimentary sequences related to the forming and alteration of CBM, tectonic movement, and burial and hydrocarbon-generation histories. The parameters were measured for independent quantities such as CBM content, gradient, coefficient of extraction difficulty and geological structure complexity. Correlation analysis was conducted between the measured parameters of CBM-bearing systems and the main controlling factors. When the controlling factors are sedimentary sequences and the sedimentary systems tract, the division of CBM-enriched units is based on the coal-forming environment, coal mass distribution and coal characteristics. When the controlling factor is the tectonic matching between the orefield, mining area and mining wells, the division of CBM-enriched units is based on tectonic movement. When burial and hydrocarbon-generation histories are the controlling factors, the division of CBM-enriched units is based on metamorphic traits.
