摘要：
沼气作为生物质能源中的一种,已广泛用于内燃机电站发电。但是沼气中H2S对内燃机的腐蚀,严重制约了内燃机的可靠使用。本文通过湿法脱硫技术对某淀粉厂消化沼气进行处理,并对脱硫前后的内燃机部件消耗进行了比较,证明了该方法的有效性和可行性,脱硫后的沼气中硫化氢浓度低于200mg/Nm3,对沼气内燃机的应用具有良好的保护作用。

Abstract: As one of the biomass energy
Biogas has been utilized as fuel in the power plants powered by internal
combustion engine broadly to generate electricity.The H2S content in biogas is
corrosive to the internal combustion engine and so constricts reliability of
the internal combustion engine.The paper discusses on treatment by wet
desulfurization technology to digester biogas from starch plant.After corrosive
comparison to main components in internal combustion engine resulted in the
desulfured or un-defulfured biogas,it is proved that the technology is
effective and feasible.After desulfuring,H2S content gets lower than
200mg/Nm3,the utilization of the technology is protective to biogas internal
combustion engine.
