Abstract
The present study deals with the catalytic decomposition of sulfones which are the oxidized sulfur compounds generated from a fuel subjected to an oxidation- desulfurization step so that to recover the hydrocarbons present in sulfones through the release of SO2 gas. Raw kerosene (2296 ppm) was oxidized (using hydrogen peroxide in a batch oxidative desulfurization technique), separated and analyzed for the sulfur content of 2004 ppm in the top phase and 985 ppm in the bottom phase. Both phases (containing the oxidized sulfur compounds) was fed separately and continuously to the trickle bed reactor loaded with the prepared Layered double hydroxide (LDH) catalyst at 250, 325, 400, and 475 ˚C,100 psi and liquid hourly space velocity (LHSV): 1 hr-1. Results showed that LDH catalyst was superior in achieving 75% of sulfones removal at 475 ˚C after 150 min compared to MgO catalyst achieving 49% using the top phase. In contrast 84% of sulfur compounds were removed when the bottom phase was introduced to the reactor under the same operating conditions. Catalyst stability during 21 hours of operation gives evidence to a promising fuel recovery process and to integrate the oxidative desulfurization. No previous study is found for the recycle of the sulfones from high sulfur content kerosene fuel in a trickle bed reactor and in both phases.
