Preparation And Characterization Of Koh Impregnated Calcined Fishbone Catalyst For Biodiesel Production From Waste Cooking

KOH/Calcined fishbone catalyst was prepared through wet impregnation process by impregnatingrn5, 10 & 15 wt% of KOH catalyst with calcined fishbone. The catalyst prepared by impregnatingrn10 wt% of potassium hydroxide in calcined fishbone as a support was found to show the bestrncatalytic activity among the prepared catalysts. The characterization of KOH/Calcined fishbonerncatalyst, supported catalyst and raw fishbone was conducted by XRD and FTIR analysis. Therneffects of various reaction variables on the yield of biodiesel were investigated. The highest yieldrnof biodiesel over KOH/Calcined fishbone catalyst was 97.46%. It was obtained at the optimumrncondition of methanol to oil ratio of 10.56, catalyst dosage of 3.96 wt%, reaction time of 2.7 h andrnthe reaction temperature at 65rnC. The physiochemical and fuel properties of biodiesel were studiedrnand it is within the biodiesel standard specification. The produced biodiesel under the optimalrnreaction condition was characterized by using FTIR and GC-MS analysis. The selected catalystrnhas been reused successfully for three catalytic cycles.
