Research of diesel fuels dewaxing process via mathematical model

Abstract

Abstract. The aim of the work is to carry out the research of diesel fuels dewaxing process. The study is based on fundamental mathematical model of the process, which takes into account poisoning of the metal centers and acid sites due to coking. Formed mathematical model was implemented for monitoring calculation with the aim of improving the efficiency of dewaxing catalyst loaded to the industrial reactor. Three operational modes were recorded for dewaxing unit. Optimization calculation of temperature at summer mode revealed that temperature in the dewaxing reactor could be decreased to 325°C without fuel quality loss.
