在交流（AC）放电等离子体和催化集成技术（PACT）反应器中，在铁和镍电极上进行模型烃（正己烷）的转化，以在室温和大气压下即时产生氢气和低碳烷烃和烯烃，用于汽车尾气净化的可能应用。金属电极对反应有催化作用，铁电极对加成反应的催化活性明显高于镍电极。碳-碳键的裂解是主要反应。己烷的催化脱氢是氢的来源。与空速相比，外加电压对功耗的影响占主导地位。能量效率将随着进料分子的停留时间的减少而增加，并且随着施加的电压的增加而降低。PACT反应器消耗的能量中最多有38%用于裂解单个碳-碳键。
Conversion of a model hydrocarbon (n-hexane) was carried out over iron and nickel electrodes in an alternating current (AC) discharge plasma and catalysis integrated technologies (PACT) reactor to instantly produce hydrogen and light alkanes and alkenes, at room temperature and atmospheric pressure, for possible application in automotive exhaust gas purification. Catalytic effects of metal electrodes are involved in the reactions, with iron electrodes showing obviously higher catalytic activity on addition reactions compared with nickel electrodes. Cracking of carbon–carbon bonds is the dominant reaction. Catalytic dehydrogenation of hexane is the source of hydrogen. Compared with space velocity, applied voltage has dominant effects on power consumption. Energy efficiency will increase as the residence time of feed molecules decreases and decrease as applied voltage increases. A maximum of 38% of the energy consumed by the PACT reactor was used for cracking single carbon–carbon bonds.
