Description
Summary:The concept of “waste-to-wealth” is spreading awareness to prevent global warming and recycle the restrictive resources. To contribute towards sustainable development, hydrogen energy is obtained from syngas (CO and H 2 ) generated from waste gasification, followed by CO oxidation and CO 2 removal. In H 2 generation, it is key to produce more purified H 2 from syngas using heterogeneous catalysts. In this respect, we prepared Pt/Al 2 O 3 catalyst with nanoporous structure using precipitation method, and compared its catalytic activity with commercial alumina (Degussa). Based on the results of XRD and TEM, it was found that metal particles did not aggregate on the alumina surface and showed high dispersion. Optimum condition for CO conversion was 1.5 wt% Pt loaded on Al 2 O 3 support, and pure hydrogen was obtained after removal of CO 2 gas.
