Abstract

The oxidative desulfurization (ODS) of real diesel fuel was evaluated in a modified design oscillatory helical baffled reactor (OHBR). Peracetic acid was produced from hydrogen peroxide and acetic acid and used as an oxidant. Following that, we used a new design from nano-catalyst (uncoated and coated). The experimental work of oxidative desulfurization process was utilized in an oscillatory helical baffled reactor under moderate conditions: residence times (3-9) min, oxidation temperatures (50-80) oC, oscillation of amplitude (2-8) mm, and oscillation of frequency (0.5-2) min with 0.4g of nano-catalyst with constant pressure. The objective of this manuscript is to obtain the ODS kinetic parameters and concentration profile of the sulfur compounds in real diesel fuel. The model developed was according to the properties of the real diesel fuel, types of nano-catalyst, and operation conditions inside the OHBR based on the experimental observations. Here, the optimal kinetic model and the half-life period of the nano-catalysts for the pertinent reactions have also been examined.
