Abstract

SILP (supporting ionic liquid phase) catalysts for peroxide thiophene oxidation were obtained on silica gel, they included imidazole cations with sulfonic acid group and phosphotungstate anions. The composition of the active phase and the surface structure of the catalysts are characterized by a set of modern physicochemical methods, including mass spectrometry using the SALDI technique. It was found that the organic cation structure affects the stability of heteropolyanions, decomposition processes in the SILP and the catalytic properties of the samples. SILP catalysts are effective in desulfurization of the diesel fraction and provide fuel with an S content of less than 10 ppm.

磷酸钨多相催化剂SILP氧化脱硫的研究：离子液体的作用

摘要

在硅胶上获得了用于过氧化物噻吩氧化的SILP（负载型离子液体）催化剂，其中包括带有磺酸基的咪唑阳离子和磷钨酸根阴离子。活性相的组成和催化剂的表面结构通过一系列现代物理化学方法来表征，包括使用SALDI技术进行质谱分析。发现有机阳离子结构会影响杂多阴离子的稳定性，SILP中的分解过程以及样品的催化性能。SILP催化剂可有效去除柴油馏分，并提供S含量小于10 ppm的燃料。
