The synthesis of SAPO-34 catalyst in the presence of activated carbon and the study of methanole transformation process into the olephines

Abstract

The paper deals with the results of transformation process of methanol into the low molecule in the presence of silicoalumophosphate (SAPO-34) catalyst synthesized via sonochemical method with adding activated carbon. The studies on physico-chemical properties of synthesized catalyst with up-to-date analysis methods are presented as well. It was revealed that without adding the water into the raw, the C2-C4 olephine yield in the first hour of process comprises 66– 69 % mass, while applying raw-water mixture, the parameter increases up to 80–82 % mass. It is explained with the fact that the water increases the efficient service life of the catalyst due to the partial prevention of coke formation.
