Fast, non-extractive, and ultradeep desulfurization of diesel in an oscillatory baffled reactor

Sulfur compounds are major contaminants in diesel fuels and cause significant negative impacts on the environment, human health, petroleum product quality. Oxidative desulfurization (ODS) has gained attention due to relatively mild operating conditions. However, ODS requires improvements terms of productivity, reaction time, conversion. This study reports development a highly efficient, rapid process, an oscillatory baffled reactor (OBR), allow continuous, safe dibenzothiophene (DBT) removal. DBT conversion was studied as function temperature, residence oscillation frequency, amplitude. By optimizing conditions, up 94 % could be removed without further extraction 3 min, at 80 °C, 4 Hz, 6 mm. is substantial increase over comparable processes this temperature furthermore been conducted that scales predictably, hence it probable performance can realized industrial scale.
