Investigation on Plasma-Driven Methane Dry Reforming in a Self-Triggered Spark Reactor

摘要: The performance of methane dry reforming in a self-triggered spark discharge reactor is evaluated terms conversion reagents, yield and selectivity desired products (syngas), energy efficiency. effects feed gas composition (CO2:CH4 ratio), flow rate input electrical power were investigated. process very good: under the best experimental conditions 1:1 at 100 mL · min−1, 20 W) (71% for CH4 65% CO2), (78% H2 86% CO), efficiency (2.3–2.4 mmol · kJ−1) are all quite high. formation ethane, ethylene, acetylene was also detected analyzed as function CO2:CH4 ratio. As ratio decreased below 1, both CO2 slightly increases, but syngas decreases favoring C2 hydrocarbons appearance carbon deposits. Increasing from 0.5 to 1.5 has virtually no effect on reagents production promotes CO reduces that hydrocarbons. determined be 1.0 considering lowest water byproduct optimal stability.
