Abstract:

Catalytic aqueous phase reforming (CAPR) of the biomass has a great potential for the production of H2 and hydrocarbons. This study reports synthesis of novel nanoscale bifunctional catalytic material and its utilization in CAPR process for the conversion of waste biomass into H2 and hydrocarbons. Synthesis of catalyst involved the dissolution of a metal salt precursor in ethanol/water solution containing surfactants such as Brij-76 or pluronic 123 followed by gelation using propylene oxide. As prepared gels were aged, dried, and calcined at 400-600oC. After synthesizing mesoporous support, immobilization of Ni/Ru inside the mesopores was accomplished by wet-incipient method followed by reduction in H2 environment. The catalyst was characterized using a Uv/Vis spectrophotometer, X-ray diffraction, FTIR, SEM, and TEM. The concentration of Ni/Ru in the catalytic material was analyzed with the energy dispersive spectroscopy. The results obtained on the synthesis of catalyst, characterization, and H2 and hydrocarbon production from waste biomass will be presented.
