本文报道了利用等离子体重整烃类或醇类与CO2或H2O的混合物来获得氢气。等离子体在工作于大气压和低温（即，约100°C）。该反应器在操作中具有很大的通用性和低的制造成本。结果是甲烷，甲醇和乙醇的重整。甲烷将高达70%转化为CO和H2，而不形成任何种类的上级烃。对于这两种醇，100%转化为相同的产品被发现为流量比甲烷的情况下高得多。工作报告的反应器和电源的操作条件，使等离子体的点火和稳态操作的描述。
This work reports about the use of plasmas to obtain hydrogen by reforming of hydrocarbons or alcohols in mixtures with CO2or H2O. The plasma is activated in a dielectric barrier discharge (DBD) reactor working at atmospheric pressure and low temperatures (i.e., about 100°C). The reactor presents a great versatility in operation and a low manufacturing cost. Results are presented for the reforming of methane, methanol and ethanol. Methane transforms up to a 70% into CO and H2without formation of any kind of superior hydrocarbon. For the two alcohols 100% conversion into the same products is found for flows much higher than in the case of methane. The work reports a description of the reactor and the operational conditions of the power supply enabling the ignition of the plasma and its steady state operation.
