Аннотация

The article considers the results of qualified processing of industrially produced petrolatums in order to obtain hydrotreated ceresins with improved quality indicators. It has been established that preliminary multi-stage deoiling of petrolatum allows to reduce the sulfur content by 2-3 times. It has been shown that increasing the hydrogen pressure to 4.5 MPa during hydrotreating at a temperature of 260 °C allows to obtain ceresins whose properties are not inferior to commercial samples.
