摘要:

针对柴油中所含硫是形成大气 SOx 酸雨的有害源之一的问题,开展了以硫化物为核心的柴油深度脱硫技
术研究。为了加快柴油氧化脱硫反应速度,提高脱硫率,笔者以自制合成的新型季铵盐 Gemini 表面活性剂(简记
为 DAEQ9–Cl)作为相转移催化剂,用过氧化氢–乙酸作为氧化体系,以南充炼油厂直馏柴油为研究对象,考察了
H2O2/CH3COOH/DAEQ9–Cl体系催化氧化柴油脱硫的适宜反应条件及脱硫效果。实验表明,在柴油氧化脱硫反应中,
DAEQ9–Cl 是一种优良的相转移催化剂,柴油中的硫含量降为 28µg/g,脱硫率为 96.2%。本研究对治理环境污染开展
环境保护有推广价值。

Abstract:

Aimed at the sulfur components in diesel fuel, which is one of factors that causes the formation of acid rain in
atmosphere, we investigated the deep desulfurization technology for sulfides removal. In order to speed up the diesel oil oxida-
tion desulfurization reaction and improve the desulfurization rate, homemade synthesis of new Quaternary Ammonium Gemini
surface active agent (abbreviated DAEQ9–Cl)as a phase transfer catalyst, hydrogen peroxide-acetic acid as the oxidation sys-
tem, Nanchong refinery straight-run diesel for the study, the suitable reaction conditions and catalytic oxidation desulfurization
effect of H2O2/CH3COOH/DAEQ9–Cl system diesel desulfurization was investigated. Experimental results show that, in the
oxidation of diesel desulfurization reaction, DAEQ9–Cl is a kind of fine phase transfer catalyst, sulfur content in diesel oil down
to 28 µg/g, the desulfurization rate of 96.2%. This study is significant for controlling environment pollutions and environmental
protection.
