MODIFIED HETEROSILICATES (Fe, B)-CATALYTIC CHARACTERISTICS AND IR SPECTRA

Article abstract of DOI:10.1007/BF00866574

The catalytic characteristics (in the aromatization of propane and propylene) and acidic characteristics (IR spectra in diffuse scattered light) of modified crystalline heterosilicates (Pt, Zn, Ga) were studied.It was shown that new centers, capable of substantially increasing (by 2-7 times) the yield of aromatic hydrocarbons from propane, are formed when Zn and Ga are introduced into ferri- and borosilicates.In the case of propylene the aromatizing characteristics of the modified heterosilicates show up particularly clearly in the region of relatively low temperatures.Key words: Heterosilicates, IR spectroscopy, acidic properties, modification, aromatization.
