The activity, selectivity, and stability of microporous highly dispersed zeolites (H-Y, H-ZSM-5) and granulated hierarchical zeolites (H-Yh and H-ZSM-5h) were studied in the synthesis of quinolines by the Skraup reaction. Texture, porous structure, morphology of crystals, acidic properties were characterized by XRD, XRF, N2 adsorption-desorption, SEM, NH3-TPD methods. It was found that quinoline, 2- and 4-methylquinolines are the main products in the reaction of aniline with glycerol in the presence of the studied catalysts. H-ZSM-5h and H-Yh catalysts are more efficient than catalysts H-ZSM-5 and HY and provide a yield of quinolines to 72.4 (H-ZSM-5h) and 60.2 % (H-Yh) at 450 °C, 0.2 h−1, the molar ratio of aniline:glycerol=1 : 3. The high activity and selectivity of hierarchical zeolites are due to the presence of meso- and macropores, as well as nanocrystals of 15–100 nm size. It was reported that hierarchical catalysts exhibit higher stability in the reaction compared with microporous zeolites.
