Abstract
The promotion of biogas energy has been constrained by the presence of H2S. Classical H2S photodegradation is typically carried out with oxygen present, but this is inappropriate for biogas desulfurization and must be prevented. Thus, the current study was to examine the UV degradation of H2S without O2 from a mathematical perspective. This paper was performing a theoretical investigation of UV degradation of H2S without oxygen. First, the Homotopy perturbation approach was used to construct a theoretical computer model on H2S photodegradation. This model included models for the distribution of gas flows, radiation kinetics in the photoreactor, mass balance, and degradation rate. Then, to verify the mathematical model, the effects of the initial H2S concentration and gas retention duration on the photodegradation rate were examined. To validate the mathematical model, the effects of factors on the initiative H2S mass and gas retention time toward the photo-degradation rate were investigated. The primary photodegradation products were identified as elemental S and H2.
