Hydrogen-rich Gas Production from Propane using Plasma-assisted Reforming
E-mail:
The reforming characteristics and optimal operating condition for syngas (synthesis gas) production were studied by using gliding arc plasma with a catalytic reactor. Parametric screening studies were undertaken for variations of the following variables: vapor flow ratio, CO2 flow ratio, reactant flow rate, and input electric power. When these variables were 0.65, 0.14, 14 L/min, and 1.37 kW, respectively, the production of hydrogen-rich gas was maximized with an optimal propane conversion rate of 62.6 %. Under these optimal conditions, the following syngas concentrations were determined: H2, 44.4 %; CO, 18.2 %; CH4, 11.2 %; C2H2, 2.7 %; C3H6, 1.9 %; C2H4, 0.6 %; and C3H4, 0.4 %. The carbon dioxide conversion rate was 29.2 % and the H2/CO ratio was 2.4.
