Synthesis of Ni/SBA-15 For CO2 Reforming of CH4: Utilization Of Palm Oil Fuel Ash As Silica Source

In this study, Ni/SBA-15 was synthesized using Palm Oil Fuel Ash (POFA) as the silica source and was applied in the CO2 reforming of CH4 (CRM). The preparation of POFA sodium silicate (POFA-Na2SiO3) was carried using sodium hydroxide (NaOH) fusion method under several parameters including NaOH/POFA...
