摘要
With the aim of directly producing a high-quality syngas with a ratio of H_(2)/CO=2,bi-reforming of CH_(4)with the ideal stoichiometric ratio of CH_(4)/CO_(2)/H_(2)O=3/1/2 is carried out in a gliding arc-based warm plasma catalytic reactor.The gliding arc plasma is a typical warm plasma(WP),which provides favorable conditions for CO_(2)activation,and it is found that the highest conversions are obtained in the case of reaction using the WP alone.A comparison of reactions using the WP alone(the WP case),the conventional catalyst alone(the CC case),and the WP plus catalyst(the WPC case)reveals that the WPC case can overcome the disadvantages of both the WP and CC cases.In the WPC case,CH_(4),CO_(2),and H_(2)O react at the ideal stoichiometric ratio of CH_(4)/CO_(2)/H_(2)O=3/1/2.In addition,higher reactant conversions and energy efficiencies are obtained in the WPC case than in the WP case.A high-quality syngas with H_(2)/CO=2 is obtained,with similar conversions of(89±1)%for all of CH_(4),CO_(2),and H_(2)O and an energy efficiency of 71%.
