摘要
A novel type of four-impinging-jets reactor (FIJR) has been proposed and tested successfully for the oxidative desulfurization of kerosene as a typical light fuel oil. The FUR is characterized by a high-intensity mixing chamber located at the bottom of the reactor and equipped with four impinging jets. The influences of various operating and design parameters such as feed flow rate, internozzle distance, jet diameter, and jet Reynolds number on the performance of the FUR have been carefully investigated. As a result of both the impinging process and shear forces exerted on the phases, the rate of desulfurization in FIJR increased significantly compared to that obtained by a conventional reactor system such as stirred-tank reactor (STR). This can be attributed to a decrease in the mass-transfer resistance, complex flow pattern within the reaction chamber, energy released as the result of impinging-jets collision, and high intensity mixing at the impingement zone of FIJR. Moreover, about 92% sulfur removal of kerosene has been obtained in FIJR.
