Abstract

Zeolite-containing materials of various structural types (MFI, MEL, MTW) were prepared by the hydrothermal method using organic templates based on quaternary polymethylenediammonium salts. The materials were characterized by X-ray diffraction analysis, low-temperature nitrogen adsorption–desorption, temperature-programmed ammonia desorption, IR spectroscopy, scanning electron microscopy, X-ray fluorescence analysis, transmission electron microscopy, solid-state ²⁷Al NMR spectroscopy, and IR spectroscopy of adsorbed pyridine. The effect of the template on the structure of the material obtained was revealed.

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
