Computer-based model of crude oil gasification in a fluidized bed

Gasification is a high-temperature, low-cost, and environmentally friendly process with uses as an alternative method to convert the carbon-based fuels into a clean syngas for engineering applications. In this work, the authors developed a mathematical model of crude oil for evaluating the crude oil potential to produce a clean and high caloric value syngas. The influence of some critical parameters during crude oil gasification including equivalence ratio, excess oxygen ratio (EOR), and residence time on tar yield, syngas caloric value, and char conversion was investigated. Results showed that with increasing the EOR, the char was converted continuously due to a significant improvement in the nature of endothermic reactions involved. It is also found that when the EOR increases from 0.2 to 0.8, gas caloric value improves, slightly.
