Co-generation of synthesis gas and C2+ hydrocarbons from methane and carbon dioxide in a hybrid catalytic-plasma reactor: A review

Preliminary Testing of Hybrid Catalytic-Plasma Reactor for Biodiesel Production Using Modified-Carbon Catalyst

“…There is synergetic effect between plasma system (containing high energetic electrons, excited atoms, and neutral particles) with heterogeneous surface catalysis roles. The synergism is possible in activating the reactants in the discharge zone or even to assist cracking the covalent bonding of reactants before the main reaction takes place and finally giving a positive effect on the reaction mechanism and rate [30,31].…”

“…This type of reactor is also potential for reactions of organic and inorganic chemicals because of its non-equilibrium. The hybrid catalytic -Dielectric Barrier Discharge (DBD) plasma reactor is very promising because of high conversion rates, shorter reaction time, and more efficient power requirement [31]. Meanwhile, the catalyst placed in the discharge zone is an alternative solution to improve the selectivity of reaction to produce biodiesel [32].…”

“…This phenomenon is caused by the ability of plasma to influence the reaction through collisions of high energetic electrons from electrode and electrons pairs from the chemical bonding. During the plasma process, the energetic electrons interfere the electrons pairs of covalent bonding of the reactants that would be excited or dissociated so that the activation energy required during surface reaction in the catalyst surface could be reduced [22,23,31]. Without the role of plasma, the time of reaction required to form FAME would be longer as studied by Ketchong et al [24].…”

Carbon dioxide reforming of methane in kilohertz spark‐discharge plasma at atmospheric pressure

“…1 However, there exist some major drawbacks for the catalytic CDR reaction: the high temperature required and the rapid deactivation due to coke and sulfur poisoning. A desirable alternative is the use of nonthermal plasma, in which the collision of energetic electrons with gas molecules can produce radicals to induce chemical reactions, resulting in very high methane conversion at relatively low temperature in comparison with the conventional catalytic process.…”

Influence of Discharge Voltage-Current Characteristics on CO2 Reforming of Methane using an Elongated Arc Reactor

“…그러나 촉매를 이용한 CO 2 개질은 탄소 침적의 문제로 인해 공정의 운전조건이 제한적이라는 단점 이 지적됨에 따라, 최근에는 이러한 문제로부터 자유 로운 플라즈마를 이용한 CO 2 개질공정에 관한 연구가 활발히 진행되고 있다 (Hwang et al, 2008;Istadi and Amin, 2006;Li et al, 2004;Oberreuther et al, 2003;Zhang et al, 2002;Huang et al, 2000). (Kim et al, 2008).…”
