Deep desulfurisation performance of thiophene with deep eutectic solvents loaded carbon nanotubes composites

One source of air pollution is the combustion of sulfur compounds in fuel oil. Reducing sulfur content in fuel oil has become a hot issue demanding timely solutions. Using ionic liquids (ILs) and deep eutectic solvents (DESs) to remove sulfides in fuel oil has achieved good results presently. However, since DESs are liquid and their transportation and separation are inconvenient, a new way is proposed that the DESs are loaded on the carbon nanotubes (CNTs) with large specific surface area and good chemical stability. A series of composites materials (DESs/CNTs) were prepared. Finally, they are applied to the removal of sulfides in fuel oil. This loading method, which imparts introduced unique Physico-chemical properties of the DESs to the carrier materials, preserves both advantages while overcoming some of the problems with DESs. The interaction between DESs and CNTs is mutual promotion. Therefore, this study has important theoretical significance and industrial application value. Unde...

大气污染的来源之一为燃料油中含硫化合物的燃烧。降低燃料油中的硫含量已成为亟待解决的热点课题。目前，采用离子液体（ionic liquids，ILs）与深共熔溶剂（deep eutectic solvents，DESs）脱除燃料油中硫化物的技术已取得良好成效。然而，由于深共熔溶剂呈液态，其运输与分离存在诸多不便，本研究据此提出一种新方案：将深共熔溶剂负载于比表面积大、化学稳定性优异的碳纳米管（carbon nanotubes，CNTs）之上。随后制备了一系列DESs/CNTs复合脱硫材料，并将其应用于燃料油硫化物的脱除工艺。该负载方式可赋予载体材料深共熔溶剂独特的理化性质，在兼顾二者优势的同时，解决了深共熔溶剂自身存在的部分弊端。深共熔溶剂与碳纳米管之间存在相互促进的协同效应。因此，本研究具备重要的理论意义与工业应用价值。Unde...
