Abstract
Biodiesel as an alternative fuel option has a high priority to scientists’ researches, even in the periods when petroleum has low prices, as there are great predictions for the end of the era of fossil fuel. Alkali transesterification of vegetable oils is the main process used commercially for the biodiesel production, and using waste cooking oils overcomes the issue of high feedstock prices and help in solving the waste oil treatment process. A rigorous model using detailed kinetic reactions for the alkali transesterification of waste cooking oil with Methanol and Alkali Catalyst (NaOH) was simulated using Aspen Plus software. The rigorousness of the model help in predicting more realistic and accurate results. Case studies were conducted to study the effect of different parameters on the process such as temperature, pressure, residence time, methanol to oil ratio, and catalyst (NaOH) percentage. Optimization of the process also carried out to find the best conditions for maximum profit and maximum yield.
