Hydrogen-free upgrading on ZSM-5 type zeolite catalyst – efficient way to obtain low-freezing diesel fuel

Abstract

The process of hydrogen-free upgrading of diesel fraction on ZSM-5 type zeolite catalyst was implemented at the laboratory catalytic unit under the conditions of varying the process temperature. The composition and characteristics of the feedstock diesel fraction and the obtained upgrading products were investigated. The obtained diesel fraction upgrading products were tested for compliance with the standards. The directions of hydrocarbon transformations in the process of upgrading on a zeolite catalyst were considered. The influence of the upgrading process temperature on the composition and characteristics of the obtained products was estimated. For the first time, the optimal technological parameters for the implementation of the upgrading process on a zeolite catalyst from the perspective of the production of arctic diesel fuel were determined.
