| Title: The modeling and simulation of SDS promoting CO2 hydrate formation in coal surface | |
| Abstract: Geological sequestration of CO2 has been reported to be a viable mean to migrate the global temperature rising. Coal as the porous structure is becoming an effective media to store CO2 as hydrate formation method. However, there is one critical problem prohibiting the forming rate of the hydrates is that the principle of the surface reaction existing among gas(CO2)-water-coal keeps unclear whilst it is very significant for deciding the controlling factors which will affect the reaction rate and also will become more complicated once considering adding the additional promoting reaction surfactant. Sodium dodecyl sulfate (SDS) was selected as the promoting agent in CO2 hydrate formation in coal which were reported can be used to accelerate the hydrates formation rate. The surface reaction principle among gas(CO2), water, SDS, and coal was carried out and aimed to provide the deep understanding for CO2 hydrate formation surface reaction in coal. Firstly, the surface reaction principle was analyzed theoretically. Secondly, the reaction kinetic mathematical equations controlling surface reaction between gas (CO2)-water-coal with SDS were established further. The lattice simulator was employed to compute the surface reaction process and the initial parameters values and the boundary conditions were designed. The simulation results were compared to the experimental tests results in the presence of SDS under different controlling conditions and found two results fitting well. It verified the surface kinetic models and equations established are effective and can be used to control reaction parameters to accelerate the surface reaction. The conclusions also provide a deeper understanding for CO2 hydrates formation reaction in the surface of the coal. | |
