Abstract

The possibility of using a composite material (hereinafter referred to as composite) based on silica gel modified with particles of Fe(III) compounds for the highly efficient purification of contaminated transformer oils and batches of oils for long-term storage is investigated. The KSKG silica-derived composite modified with particles of Fe(III) compounds with an iron content of about 7 wt % (SiO₂-7Fe-Amk-600) is found to be more effective when compared with pure KSKG silica gel for removing both acid activators for sludge formation and oil-degradation products from transformer oils. The preservation of the basic properties of oil after its purification on the SiO₂-7Fe-Amk-600 composite and storage for 2 years in contact with this composite indicates the possibility of using the new SiO₂-7Fe-Amk-600 composite as a stabilizer for the original and purified transformer oils.

评估含铁复合材料在净化变压器油中的适用性

摘要

研究了使用以Fe（III）化合物的颗粒改性的硅胶为基础的复合材料（以下称为复合材料）来高效净化受污染的变压器油和批量油以进行长期存储的可能性。发现与纯KSKG硅胶相比，用铁含量约为7 wt％的Fe（III）化合物颗粒改性的KSKG二氧化硅复合材料（SiO ₂ -7Fe-Amk-600）更有效用于变压器油污泥形成和油降解产物的酸活化剂。在SiO ₂上纯化后的油的基本性能保持-7Fe-Amk-600复合材料以及与该复合材料接触存放2年表明，有可能使用新型SiO ₂ -7Fe-Amk-600复合材料作为原始和精制变压器油的稳定剂。
