Ts. Sobokhoeva et al., Catalysts for isomerization of aromatic hydrocarbons based on natural zeolites from the Baikal region, RUS J AP CH, 72(3), 1999, pp. 457-461
A method is proposed for preparing a catalyst for isomerization of C-7-C-9
aromatic hydrocarbons, based on natural zeolites and containing no noble me
tals. The adsorption and acidic characteristics of catalysts based on clino
ptilolite and chabazite were studied by X-ray photoelectron and IR spectros
copy and by gas-liquid chromatography.
