轻质油品非加氢脱硫技术*

日益严格的环保法规,对生产低硫、超低硫清洁油品技术提出了更高的要求。传统的加氢脱硫技术存在投资大、运行成本高等问题，因此开发成本低、操作条件温和的非加氢脱硫技术成为一种趋势。本文综述了目前轻质油品非加氢脱硫的相关技术,主要包括氧化脱硫、吸附脱硫和生物脱硫等技术的研究进展；简要介绍了萃取脱硫、络合脱硫、催化裂化脱硫、烷基化脱硫、膜分离脱硫及离子液体脱硫等技术;同时对轻质油品非加氢脱硫技术的应用前景进行了展望。

Nonhydrodesulfurization Technologies of Light Oil

Due to increasingly stringent regulations for the environmental protection purpose, the requirement for the production technology of the low sulfur and ultra-low sulfur clean oll is becoming rigor. The conventional hydrodesuffurization technologies have several problems, such as higher investment and operating cost. Consequently, the investigation of nonhydrogenation technologies is becoming popular, because these novel technologies have the advantages of lower investment and much milder operating conditions. Several nonhydrodesulfurization technologies and processes of light oil are reviewed in this paper, mainly including oxidative desulfurization, adsorptive desulfurization and biodesulfurization. In addition, the technologies of desulfurization by extraction, complexation, catalytic cracking, alkylation, membrane separation and ionic liquids are described briefly. The opinions with respect to the future application trend of nonhydrodesuffurization of light oil are proposed.
