| Summary: |
Biohydrogen is a renewable source of clean fuel and energy which can be derived from
biomass. One of the suitable candidate as a source of biomass is palm kernel shell (PKS). An
effective approach to produce hydrogen rich gas is via catalytic gasification as the catalyst may
promote high content of product gases and eliminate tar. The potential of using Ceria (Ce02) and
Titania (TiOi) supported catalysts for the production of biohydrogen from PKS were explored
using Fe and Cu as the active metals with 2.5, 5, 7.5 and 10 wt% metal loading. The catalysts
were prepared by incipient wetness impregnation method for 4 hours, dried at 120°C and
calcined P+ ^flO °C for 16 h The nhvcicrichernieal nrrvnerties nf these catalvsts were characterized
using XRD, N2 adsorption-desorption isotherm, TPR and FESEM. Catalysts screening was
performed in dry PKS gasificationusing Temperature Programmed Gasification (TPG) system at
temperature range of100 - 700 °C in 5% 02/He ata flow rate of 10 ml min"1 with PKS weight of
0.3 g and PKS to catalyst ratio of 3. The gaseous products formed namely H2, CO2, CO and CH4
were detected by mass spectrometer, following its m/z = 2, 44, 28, and 16 respectively. |
