Hydrogen-Rich Gas Production with the Ni-La/Al2O3-CaO-C Catalyst from Co-Pyrolysis of Straw and Polyethylene

Ni-based catalysts have been extensively investigated because of their superior catalytic performance. In this study, the Ni-La/Al2O3-CaO-C catalyst was prepared by homogeneous precipitation, employed in co-pyrolysis soybean straw with polyethylene to produce hydrogen. The optimal experimental conditions were identified discussing carrier synthesis ratio, feedstock and addition La. Additionally, stability evaluated. It established that produced using a molar raw ingredients ratio 5:5, optimum action obtained when La added. Co-pyrolysis (PE) catalyzed generated 55.45 vol% H2 under ideal circumstances. After six applications, yield 33.89 vol%, compared 27.5 for Ni/Al2O3-CaO-C catalyst. results indicate exhibits activity than Ni/Al2O3-CaO-C.
