Computer Simulation of Laser Radiation Influence at Internal Flows of Reactive Hydrocarbons

Numerical model is proposed for thermal synthesis of hydrogen and valuable unsaturated hydrocarbons from light alkanes by laser radiation. The chemical synthesis of these products occurs in internal laminar flows of multicomponent gas through radical reactions. Our computational algorithm is based on the fractional steps method for splitting physical processes. It has been verified on analytical solutions, including a novel medium-temperature one. The numerical model has been validated through comparison with experimental data from ethane pyrolysis with radical chain reactions. We have calculated the laser radiation effect on the conversion of ethane in a flat pipe. The efficiency of laser radiation in intensifying the chemical processes of hydrocarbon pyrolysis has been shown. The numerical model we designed can be used in development of modern hydrogen energy technologies.
