In this work, catalytic cracking of waste fish oil (WFO) to bio-fuel for ă diesel engine was studied over hybrid catalysts (Sodium carbonate ă Na2CO3/Magnesium oxide). The experiments were conducted using a fix-bed ă reactor. The effect of catalyst-to-WFO ratio and the amount of each ă catalyst were studied over the yields of bio-oil and acid value AV, of ă the bio-oil following central composite design (CCD). The statistical ă analysis showed that catalyst significantly affected the bio-oil yield ă and acid value. A higher bio-oil yield over 70 wt% with a lower acid ă value (2.7 mg(KOH)/g(oil)) were identified at catalyst-to-WFO of 1:7 by ă using the same amount of sodium carbonate and magnesium oxide. The ă optimum bio-oil was analyzed and properties have been investigated and ă compared to diesel fuel physical properties.
