EVOLUTION AND ROLE OF THE DEWAXING PROCESS IN OIL REFINING

Abstract

Currently, the dewaxing process is used throughout the oil industry. There is a lot of research and interest in this process as necessary in the production of fuels for cold regions, as well as lubricating oils. For dewaxing, mesoporous high-silica zeolites with different structures have been used for a long time, offering sufficient activity in the process. Dewaxing can be divided into several types and is actively used not only in the oil industry, but also in biology and medicine. In this article, an overview of the dewaxing process development stages and the most popular research on this topic was made, various indicators and physicochemical parameters were considered.
