Catalytic Biomass Reforming for Hydrogen and Hydrocarbon Production

摘要

This paper reports synthesis of catalyst nanoparticles using sol-gel method involving the addition of metal salt precursor and a surfactant in ethanol followed by gelation using propylene oxide. As prepared gels were dried, calcined at 600°C and characterized using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The catalyst nanoparticles were used for thermochemical processing of liquefied biomass (750 mg/L) obtained after subcritical aqueous phase treatment of paper waste at 250°C to investigate H_2 and hydrocarbon generation. The nanoparticles were centrifuged and the processed liquefied biomass obtained after thermochemical processing was analyzed using TOC analyzer and GC-MS. The catalyst nanoparticles were capable of producing H_2 and oxygenated hydrocarbons from a liquefied biomass containing dissolved organic carbon at a concentration of 750 mg/L.
