Abstract: A method is provided for effecting the removal of polychlorinated biphenyls from hydrocarbon oils, such as transformer oil, contaminated with more than 50 ppm of such polychlorinated biphenyls. There is utilized in the contaminated oil, while it is being agitated, dispersed metallic sodium, an aprotic ion-complexing solvent, for example, diglyme, and an oil-soluble electron carrier, such as naphthalene.
Abstract translation: 提供了一种方法，用于从含有多于50ppm的多氯联苯污染的烃油，如变压器油中除去多氯联苯。 在受污染的油中，被搅拌的时候，分散的金属钠，非质子离子络合溶剂，例如二甘醇二甲醚，以及油溶性的电子载体（如萘）被利用。

Abstract: Process for removing phenols from phenol-containing streams such as coal liquids by contacting the stream with a multivalent metal composition selected from the group consisting of oxides and/or hydroxides of one or more multivalent metals capable of forming a hydroxy metal phenate with the phenols of the stream; separating the hydroxy metal phenate from the treated stream; and heating the hydroxy metal phenate to its decomposition temperature, thereby forming phenols and oxides of the multivalent metal.

Abstract: A process fluid is purified of strongly acidic impurities, preparatory to treatment over a catalyst or over a hydrogen sulphide absorbing material, by contact with one or more alkali metal aluminates, preferably a beta alumi aluminate. Such aluminates have a high capacity for absorbing hydrogen halides. The process fluid is especially a naphtha hydrocarbon to be reacted with steam to give a gas of high methane content.
Abstract translation: 通过与一种或多种碱金属铝酸盐，优选β铝酸铝接触，将工业流体纯化为强酸性杂质，准备在催化剂上或硫化氢吸收材料上进行处理。 这种铝酸盐具有高吸收氢卤化物的能力。 过程流体特别是与蒸汽反应以产生高甲烷含量的气体的石脑油烃。

Abstract: LUBRICATING OIL FRACTIONS ARE TREATED WITH FINELY DIVIDED DISPERSIONS OF FREE ALKALI METALS OF ONE MICRON OR LESS TO REMOVE NON-BASIC AND WEAKLY BASIC NITROGEN COMPOUNDS AND THEREBY REDUCE THE COLOR AND INCREASE THE COLOR STABILITY OF THE OIL. FINELY DIVIDED SOODIUM IS PARTICULARLY EFFECTIVE. THE PROCES IS BEST CARRIED OUT BY DISTILLING THE OIL FROM A MIXTURE OF THE OIL AND THE METAL. HYDROFINING EITHER BEFORE OR AFTER THE ALKALI METAL TREAT OR BOTH FURTHER IMPROVES THE OIL.
