为实现高能效、低能耗的车载制氢，在绝热滑动弧等离子体反应器中，以空气为氧化剂，对甲醇氧化热解重整（OPR）进行了探索。考察了氧气/甲醇（O2/C）比、水蒸气/甲醇（S/C）比和比能量输入（SEI）对OPR的影响。推导了OPR中热解重整与氧化重整的反应速率比α。甲醇的OPR强烈依赖于O2/C比，甲醇转化率迅速增加。在OPR中，在O2/C比低于0.20时，甲醇转化主要通过氧化重整（部分氧化）发生，而在O2/C比高于0.20时，甲醇转化主要通过氧化重整和促进的热解重整发生，这由OPR的总反应的焓变证实。O2/C比越高，能源效率越高，能源成本越低; S/C比越高，SEI越大，能源效率越低，能源成本越高。在O2/C = 0.30、S/C = 0.5、SEI = 24 kJ/mol的条件下，甲醇转化率为88%，能量效率为74%，能量消耗为0.45 kWh/Nm 3。
To achieve on-board hydrogen production with high energy efficiency and low energy cost, the oxidative pyrolysis reforming (OPR) of methanol using air as an oxidant in a heat-insulated gliding arc plasma reactor is explored. Effects of dioxygen/methanol (O2/C) ratio, steam/methanol (S/C) ratio and specific energy input (SEI) on the OPR are investigated. The reaction rate ratio (α) of pyrolysis reforming to oxidative reforming in the OPR is deduced. The OPR of methanol strongly depends on the O2/C ratio, with which methanol conversion increases rapidly. In the OPR, methanol conversions occur mainly by the oxidative reforming (partial oxidation) at the O2/C ratios below 0.20, but by the oxidative reforming and the promoted pyrolysis reforming at the O2/C ratios above 0.20, which is confirmed by the enthalpy change for the overall reaction of OPR. Higher O2/C ratio results in higher energy efficiency and lower energy cost, however, higher S/C ratio or largerSEIleads to lower energy efficiency and higher energy cost. Under conditions of O2/C = 0.30, S/C = 0.5,SEI= 24 kJ/mol, energy efficiency of 74% and energy cost of 0.45 kWh/Nm3with methanol conversion of 88% are achieved.
