Secondary Hydrodesulfurization Reaction Kinetics Of Coke Oven Gas And Study Of Reactor Simulation

Methanol synthesis is a hot topic of today’s coal chemical industry, not only to achieve energy conservation, but also greatly enhance the economic benefits of coal chemical enterprises. Difficulty in each step of the process in the synthesis of methanol coke oven gas desulfurization requirements to enter the total sulfur content of less than0.1ppm synthetic tower hydrodesulfurization reaction and its kinetics can therefore study more in-depth discovery and address the constraints of the methanol synthesis bottlenecks.Although the two hydrogenation dry desulfurization process has been widely industrialized, but at home and abroad in the kinetics of methanol synthesis gas hydrodesulfurization almost empty, even with the dynamics of individual sulfide following:Firstconsider the sulfide individual single, not taking into account the interaction between the sulfide; the second experiment chosen gas laboratory in proportion dubbed gas, less component system simple, this is difficult to apply to industrialactual production.Hydrodesulfurization herein do take into account the dynamics of all sulfide in the coke oven gas desulfurization kinetics equation in the processing of the data will be put together to return to its parameters, taking fully into account the interaction between them, and used experimental gasKailuan Group Run coal Chemical Co., Ltd. methanol factory level hydrogenation of industrial gases, the experimental gas components more complex system closer to the actual production.Study of coke oven gas hydrodesulfurization dynamics system complex and difficult to identify a scientific and rational analysis method, this paper through a lot of research to determine the external standard method for the determination of sulfide component, hydrocarbons and inorganics three columns Contact bymethane concentration associated with the area normalization method, the comprehensive experimental early exploration collect kinetic data.Coke oven gas ideal gas, applied power function kinetic equation matlab coordinate alternation method as a tool for solving the kinetic parameters, the calculated and experimental values obtained absolute deviation does not exceed0.6ppm.Based hydrodesulfurization of coke oven gas dynamics, using a simple one-dimensional quasi-homogeneous model, two simulated industrial reactor, get results with the actual value of a more moderate, for example two industrial reactor temperature rise of22°C, the simulation results for18°C.For the front experimental industrial hydrodesulfurization two problems: First is the COS by the reaction reduced to a set value; second after each stage reactor equipment with a large amount of zinc oxide increased desulfurization tank investment and energy consumption. Both hydrogenation activity of one of the oil refining another adsorption activity of catalysts used in coke oven gas desulfurization experiments the catalyst performance was significantly better than the active catalyst.
