| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 102 === The porous media and catalytic packed bed were utilized to reform propane into syngas, and the Pt/Al2O3 catalyst is located between two porous media silicon carbide. The experiment of the partial oxidation of propane is performed to find the optimal reforming of concentration. The results show that the reaction temperature of Case A-30 PPI is relatively lower than that of Case B-65 PPI, but the concentrations of CO and H2 for Case A are higher than that for Case B. In the case of propane flow rate of 3 L/min, O2/C=0.55, Case A-30 PPI reaction chamber temperature is about 800 0C, which is lower 200 0C comparing to Case B-65 PPI. However, the concentration of H2 and CO are 28.54 % and 21.88 % respectively in Case A, which are higher than those of 24.65 % and 19.74 % in Case B respectively.
Adding steam to propane of autothermal reforming, with S/C increase from 0 to 1. Compared with S/C=0, S/C=1 in H2 concentration slightly increased from 27.41% to 30.11%, CO concentration from 20.59% down to 12.46 %. In the case of O2/C=0.7, S/C=0-0.75, the conversion efficiency of propane were up to 100 %. The yield of hydrogen can reach to 100 %. The thermal efficiency can reach to 81.87 % in O2/C=0.55, S/C =0. Hydrogen flow rate can be up to 15.18 L/min as O2/C=0.65, the S/C =1, and the output power of 2.46 kW.
