Abstract:Mesoporous silica structure SBA-15 and Al-containing SBA-15 (AlSBA) were synthesized and tested their activity in catalytic cracking of waste fatty acid mixture (palm oil based) in a fixed-bed micro-reactor. The catalytic activity of AlSBA was improved and more selective towards gasoline fraction present in the organic liquid product (OLP) as compared to mesoporous siliceous material SBA-15. Even though the hydrothermal stability of AlSBA was poorer but the sample with Si/Al ratio of 20 was found to be comparable with SBA-15. The hydrothermal stability of AlSBA was higher than AlMCM-41 with similar cracking activity and thus AlSBA is a more potential cracking catalyst.
