Prospect of African Bush Mango, kapok, Sesame, and Avocado Seeds Oils as a Feedstock for Biodiesel Production over CaSO4/Al2O3 Catalyst
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 2
Abstract
Oils extracted from the seeds of African bush mango (Irvingiag abononsis), Sesame (Sesamum indicum), Avocado (Persea americana) and Kapok (Ceiba pentandra) were transesterified with CaSO4/Al2O3 catalyst to biodiesel. High biodiesel yield was obtained from African Bush Mango Oil (90.54±2.01%) with the lowest yield from the Sesame (85.90±3.14%). The fatty acid methyl esters profile indicates methyl-9,12- octadecadienoate and methyl-11-octadecenoate as the major compounds in the produced biodiesels. The physico-chemical properties of the produced biodiesels (kinematic viscosity, flash point, cloud point, acid value etc) conform to the ASTM standard specification, except cetane value which is below the standard specification. The oil content of the seeds, Avocado (18.56 %), Kapok (32.90%), Sesame (56.77 %), and African Bush Mango (54.00%) was appreciable, indicating the viability of the seeds as source of oil for biodiesel production. The result obtained shows the efficacy of CaSO4/Al2O3 as a catalyst for biodiesel production.
