THE ROLE OF THE BINDER IN THE COMPOSITION OF CATALYSTS FOR THE HYDROISOMERIZATION PROCESS

The authors of the publication synthesized bifunctional catalysts based on mesoporous aluminosilicates (MAS) with different binder contents (80 and 65%, respectively) in two ways: the first method consisted in mixing the synthesized aluminosilicate with preliminarily activated bentonite, which was then promoted. Whereas, according to the second method, the synthesized mesoporous aluminosilicate was first promoted, only then mixed with bentonite. The synthesis of bifunctional bimetallic catalysts was carried out using the wet impregnation technique. Acid and physicochemical characteristics were studied using the DRIFT method, TPD-NH3 and the standard nitrogen adsorption/desorption method. It was found that the samples of catalysts with the ratio MAS:H-bentonite = 35:65, prepared according to the first method, have optimal acid characteristics and physicochemical properties.
